More precisely : # # _ '#@cli :: subsection' defines a new command subsection in the displayed help. # _ '#@cli command_name : arguments_format1 : arguments_format2 : ... : (qualifier)' # starts a new command description. # _ '#@cli : description' add a new description line to the current command description. # _ '#@cli : $ command_line' defines a new example of use of the current command. # _ '#@cli : $$ _pagename' tells the command has a dedicated page in the web tutorial. # #*** Specific rules for the universal plug-in 'gmic-qt': # # - A comment line starting with '#@gui' will be parsed by the plug-in to define the filters tree. # - A comment line starting with '#@gui_xx' will define a filter only for a specific language 'xx' # (e.g. 'en','fr'...). # - A comment line starting with '#@gui_xx hide(/Filter or folder name)' will hide the existing # filter of folder for the locale 'xx'. # - More precisely, the syntax of a '#@gui' comment line is : # # '#@gui Folder name' # # or # # '#@gui Command name : command, preview_command (zoom_factor)[*|+] [: default_input_mode] # '#@gui : parameter1 = typedef(arguments1...), parameter2 = typedef(arguments2...)' # '#@gui : parameter3 = typedef(arguments3...), # # where : # # 'command' is the G'MIC command name called to process the image. # # 'preview_command' is the G'MIC command name called to process the preview. # # Note that you can optionally specify a float-valued factor>=0 between parentheses at the end of # the 'preview_command' to force the default zoom factor used by the preview for this filter. # Use (0) for a 1:1 preview, (1) for previewing the whole image, (2) for 1/2 image and so on... # You can put an additional '+' sign after the parenthesis to specify the rendered preview # is still accurate for different zoom factors. Use '*' instead to tell the plug-in that the preview filter # must get the entire image rather than a thumbnail. # # # 'default_input_mode' set the default input mode for that filter. It can be # { x:none | .:active (default) | *:all | +:active & below | -:active & above | v:all visible | i:all invisible } # # 'parameter = typedef' tells about the names, types and default values of the filter parameters. # # 'typedef' can be : # # _ 'bool(default_value={ 0 | 1 | false | true })': # Add a boolean parameter (0 or 1) (as a checkbutton). # # _ 'button(_alignment)': # Add a boolean parameter (0 or 1) (as a button). # # _ 'choice(_default_index,Choice0,..,ChoiceN)': # Add a integer parameter (as a combobox). # # _ 'color(R,_G,_B,_A)': # Add R,G,B[,A] parameters (as a colorchooser). # # _ 'point(_X,_Y,_removable={ -1 | 0 | 1 },_burst={ 0 | 1 },_R,_G,_B,_[-]A,_radius[%])': # Add X,Y parameters (as a moveable point over the preview). # # _ 'file(_default_filename)', 'file_in(_default_filename)' or 'file_out(_default_filename)': # Add a filename parameter (as a filechooser). # # _ 'float(default_value,min_value,max_value)': # Add a float-valued parameter (as a float slider). # # _ 'folder(_default_foldername)': # Add a foldername parameter (as a folderchooser). # # _ 'int(default_value,min_value,max_value)': # Add a integer parameter (as an integer slider). # # _ 'link(_alignment,_label,URL)': # Display a URL (do not add a parameter). # # _ 'note(_label)': # Display a label (do not add a parameter). # # _ 'text(_is_multiline={ 0 | 1 },_default text)': # Add a single or multi-line text parameter (as a text entry). # # _ 'separator()': # Display an horizontal separator (do not add a parameter). # # _ 'value(value)': # Add a pre-defined value parameter (not displayed). # # Type separators '()' can be replaced by '[]' or '{}' if necessary (for instance if parentheses are required in # an argument of the typedef, e.g in a text). You can also replace 'typedef' by '_typedef' to tell the plug-in not # being responsive, i.e not to update the image preview when the corresponding parameter is modified. # Prepend a '~' character to the argument type (like '~typedef') to make it randomizable. # After the closing separator, you may specify a 'visibility state' character for the parameter, which can be # { _0:Hidden | _1:Grayed-out | _2:Visible (default) }, opt. followed by a propagation character that tells # if this visibility state must be propagated to neighboring non-valued interface widgets # (s.a. separator(), link() or note()). # This propagation character can be: # { +:propagate forward | -:propagate backward | *:propagate in both directions }. # # Use '_none_' as a special command or preview_command to tell the plug-in that the entry requires no G'MIC call. # # A G'MIC command can set new values for each filter parameter, through the status (see command ''status''). # To do so, the returned status must follow the syntax : # '{params1}{params2}{..}{paramsN}' where N must be exactly equal to the number of parameters # for the current filter. Optionally, you can append to each {param} its visibility state suffix ( e.g: {param}_1 ). # # A G'MIC command can also specify the output blending mode, the opacity and the position of each of the output image # (i.e. layer in the plug-in). To do so, set the image name to something like: # 'mode(grainmerge),opacity(50),pos(30,50),name(name)'. # # - Blending mode name should be the same as the argument of the 'blend' command. # - Opacity is a float number in [0,100]. # - X and Y positions are integers. # - 'name' is the layer name. # # Pre-defined plug-in variables: # # - _persistent : Variable that is shared between successive calls to the G'MIC interpreter, for a single filter. # - _preview_enabled: Boolean that tells if the preview is enabled or not. # - _preview_width: Width of the preview image. # - _preview_height: Height of the preview image. # - _preview_area_width: Width of the preview widget area. # - _preview_area_height: Height of the preview widget area. # - _preview_x0: X-coordinate of the upper-left corner of the preview (expressed in the image space). # - _preview_y0: Y-coordinate of the upper-left corner of the preview (exressed in the image space). # - _preview_x1: X-coordinate of the lower-right corner of the preview (expressed in the image space). # - _preview_y1: Y-coordinate of the lower-right corner of the preview (expressed in the image space). # - _randomized: Boolean that tells if the filter parameters have been randomized with the "Randomize" button. # # Values of variables $_preview[x/y][0/1] vary only when preview mode is set to * (full preview). # #----------------------------------------------------------------------------------------------------------------------- #--------------------------------- # #@cli :: Global Options # #--------------------------------- # This command is run when the cli tool 'gmic' is invoked without arguments on the command line. cli_noarg : v 0 use_vt100 g=$_vt100_g c=$_vt100_c n=$_vt100_n r=$_vt100_r _cli_noarg=1 version +e "\n[gmic] No commands, options or data provided." gmic_help="gmic help" if !${-is_macos}" && "!${-is_windows} gmic_help.=" | less" if $_vt100 gmic_help.=" -r" fi fi if {*,u}>0 +e "[gmic] (type "${c}"'"$gmic_help"'"$n" to print help, "${c}"'gmic demos'"$n" to launch demos)." else +e "[gmic] (type "${c}"'"$gmic_help"'"$n" to print help)." fi file_update=${_path_rc}update$_version.gmic if "isfile(['"{/$file_update}"'])" update_old:="Y = date(0); M = date(1); D = date(2); date_current = Y*365 + M*31 + D; Y = date(0,'"{/$file_update}"'); M = date(1,'"{/$file_update}"'); D = date(2,'"{/$file_update}"'); date_file = Y*365 + M*31 + D; date_current - date_file" if $update_old>=14 +e "[gmic] Command update file is "$update_old" days old, type "$g"'gmic up'"$n" to update it." fi else +e "[gmic] Fetch update and documentation from the G'MIC server." l[] { up state=${g}Success!$n onfail state=${r}Failed!$n } +e "\r[gmic] Fetch update and documentation from the G'MIC server.

The second image of the "\ "list is denoted by '[1]', the third by '[2]' and so on."\n\ "* Negative indices are treated in a periodic way: '[-1]' refers to the last image of the list, '[-2]' to the "\ "penultimate one, etc. Thus, if the list has 4 images, '[1]' and '[-3]' both designate the second image of the list."\n\ "* A named image may be also indicated by '[name]', if 'name' uses the character set `[a-zA-Z0-9_]` and does not "\ "start with a number. Image names can be set or reassigned at any moment during the processing pipeline "\ "(see command ''name'' for this purpose)."\n\ "* G'MIC defines a set of various commands and substitution mechanisms to allow the design of complex "\ "pipelines and operators managing this list of images, in a very flexible way: You can insert or remove images "\ "in the list, rearrange image order, process images (individually or grouped), merge image data together, "\ "display and output image files, etc."\n\ "* Such a pipeline can define a new custom G'MIC command (stored in a user command file), and re-used "\ "afterwards as a regular command, in a larger pipeline if necessary." _section "Image Definition and Terminology" _text \ "* In G'MIC, each image is modeled as a 1D, 2D, 3D or 4D array of scalar values, uniformly "\ "discretized on a rectangular/parallelepipedic domain."\n\ "* The four dimensions of this array are respectively denoted by:"\n\ " - `width`, the number of image columns (size along the `x-axis`)."\n\ " - `height`, the number of image rows (size along the `y-axis`)."\n\ " - `depth`, the number of image slices (size along the `z-axis`). "\ "The depth is equal to '1' for usual color or grayscale 2D images."\n\ " - `spectrum`, the number of image channels (size along the `c-axis`). "\ "The spectrum is respectively equal to '3' and '4' for usual `RGB` and `RGBA` color images."\n\ \n\ "* There are no hard limitations on the size of the image along each dimension. For instance, the number of image "\ "slices or channels can be of arbitrary size within the limits of the available memory."\n\ "* The `width`, `height` and `depth` of an image are considered as _spatial_ dimensions, while the `spectrum` has a "\ "_multi-spectral_ meaning. Thus, a 4D image in G'MIC should be most often regarded as a 3D dataset of multi-spectral "\ "voxels. Most of the G'MIC commands will stick with this idea (e.g. command ''blur'' blurs images only along the "\ "spatial `xyz`-axes)."\n\ "* G'MIC stores all the image data as buffers of `float` values (32 bits, value range '[-3.4E38,+3.4E38]'. "\ "It performs all its image processing operations with floating point numbers. Each image pixel takes "\ "then 32bits/channel (except if double-precision buffers have been enabled during the compilation of the software, "\ "in which case 64bits/channel can be the default)."\n\ "* Considering `float`-valued pixels ensure to keep numerical precision when executing image processing "\ "pipelines. For image input/output operations, you may want to prescribe the image datatype to be different than "\ "`float` (like `bool`, `char`, `int`, etc.). This is possible by specifying it as a file option when using "\ "I/O commands (see section ''Input/Output Properties'' to learn more about file options)." _section "Items of a Processing Pipeline" _text \ "* In G'MIC, an image processing pipeline is described as a sequence of items separated by the "\ "__space__ character. Such items are interpreted and executed from the left to the right. For instance, "\ "the expression:"\n\ "~~~\nfilename.jpg blur 3,0 sharpen 10 resize 200%,200% output file_out.jpg\n~~~\n"\ "defines a valid pipeline composed of nine G'MIC items."\n\n\ "* Each G'MIC item is either a __command__, a list of __command arguments__, "\ "a __filename__ or a special __input string__."\n\ "* Escape characters '\\' and double quotes '\"' can be used to define items containing spaces or "\ "other special characters. For instance, the two strings `single\\ item` and `\"single item\"` "\ "both define the same single item, with a space in it." _section "Input Data" _text \ "* If a specified G'MIC item appears to be an existing filename, the corresponding image data "\ "are loaded and inserted at the end of the image list (which is equivalent to the use of `input filename`). "\n\ "* Special filenames `-` and `-.ext` stand for the standard input/output streams, optionally "\ "forced to be in a specific 'ext' file format (e.g. `-.jpg` or `-.png`). "\n\ "* The following special input strings may be used as G'MIC items to create and insert new "\ "images with prescribed values, at the end of the image list:"\n\ " - '[selection]' or '[selection]xN': Insert 1 or N copies of already existing images. "\ "'selection' may represent one or several images (see section ''Command Items and Selections'' to learn more "\ "about selections)."\n\ " - 'width[%],_height[%],_depth[%],_spectrum[%],_values[xN]': Insert one or N images with specified "\ "size and values (adding '%' to a dimension means __\"percentage of the size along the same axis\"__, "\ "taken from the last image '[-1]'). Any specified dimension can be also written as "\ "'[image]', and is then set to the size (along the same axis) of the existing specified image "\ "'[image]'. 'values' can be either a sequence of numbers separated by commas ',', "\ "or a mathematical expression, as e.g. in input item '256,256,1,3,[x,y,128]' which "\ "creates a `256x256` RGB color image with a spatial shading on the red and green channels. "\ "(see section ''Mathematical Expressions'' to learn more about mathematical expressions). "\n\ " - '(v1,v2,..[:delimiter | axis_order])[xN]': Insert one or `N` new images from specified prescribed values. "\ "Value separator inside parentheses can be ',' (column separator), ';' (row separator), '/' (slice separator) or "\ "'^' (channel separator). For instance, expression '(1,2,3;4,5,6;7,8,9)' creates a 3x3 matrix (scalar image), "\ "with values running from 1 to 9. "\n\ " - '(\\'string\\'[:delimiter])[xN]': Insert one or N new images from specified string, by filling "\ "the images with the character codes composing the string. When specified, 'delimiter' tells about "\ "the main orientation of the image. Delimiter can be 'x' (eq. to ',' which is the default), "\ "'y' (eq. to ';'), 'z' (eq. to '/') or 'c' (eq. to '^'). "\ "When specified delimiter is ',', ';', '/' or '^', the expression is actually equivalent to "\ "'({\\'string\\'[:delimiter]})[xN]' (see section ''Substitution Rules'' for more information on the syntax)."\n\ " - '0[xN]': Insert one or N new `empty` images, containing no pixel data. "\ "Empty images are used only in rare occasions."\n\ \n\ "* Input item 'name=value' declares a new variable 'name', or assign a new string value to an existing variable. "\ "Variable names must use the character set `[a-zA-Z0-9_]` and cannot start with a number. "\n\ "* A variable definition is always local to the current command except :"\n\ " - When it starts by the underscore character '_'. In that case, it becomes also accessible by any command invoked "\ "outside the current command scope (global variable)."\n\ " - When defined in a _subcommand_ of the current command, a variable becomes also accessible in the parent command. "\ "A _subcommand_ of a command `foo` is a command whose name starts with `__foo_` (e.g. `__foo_sub`) and that is called "\ "from `foo`."\n\ "* If a variable name starts with two underscores `__`, the global variable is also shared among different threads "\ "and can be read/set by commands running in parallel (see command ''parallel'' for this purpose). "\ "Otherwise, it remains local to the thread that defined it."\n\ "* Numerical variables can be updated with the use of these special operators: "\ "'+=' (addition), '-=' (subtraction), '*=' (multiplication), '/=' (division), '%=' (modulo), '&=' (bitwise and), "\ "'|=' (bitwise or), '^=' (power), '<<=' and '>>' (bitwise left and right shifts). For instance, 'foo=1' 'foo+=3'."\n\ "* Input item 'name.=string' appends specified `string` at the end of variable 'name'."\n\ "* Input item 'name..=string' prepends specified `string` at the beginning of variable 'name'."\n\ "* Multiple variable assignments and updates are allowed, with expressions: 'name1,name2,...,nameN=value' or "\ "'name1,name2,...,nameN=value1,value2,...,valueN' where assignment operator '=' can be replaced by one of the "\ "allowed operators (e.g. '+=')."\n\ "* Variables usually store numbers or strings. Use command ''store'' to assign variables from image data "\ "(and syntax `input $variable` to bring them back on the image list afterwards)." _section "Command Items and Selections" _text \ "* A G'MIC item that is not a filename nor a special input string designates a 'command' "\ "most of the time. Generally, commands perform image processing operations on one or several available images "\ "of the list."\n\ "* Reccurent commands have two equivalent names ('regular' and 'short'). For instance, command names "\ "'resize' and 'r' refer to the same image resizing action."\n\ "* A G'MIC command may have mandatory or optional __arguments__. Command arguments must be specified "\ "in the next item on the command line. Commas ',' are used to separate multiple arguments of a single command, "\ "when required."\n\ "* The execution of a G'MIC command may be restricted only to a __subset__ of the image list, by "\ "appending '[selection]' to the command name. Examples of valid syntaxes for 'selection' are: "\n\ " - 'command[-2]': Apply command only on the penultimate image '[-2]' of the list."\n\ " - 'command[0,1,3]': Apply command only on images '[0]', '[1]' and '[3]'."\n\ " - 'command[3-6]': Apply command only on images '[3]' to '[6]' (i.e, '[3]', '[4]', '[5]' and '[6]')."\n\ " - 'command[50%-100%]': Apply command only on the second half of the image list."\n\ " - 'command[0,-4--1]': Apply command only on the first image and the last four images."\n\ " - 'command[0-9:3]': Apply command only on images '[0]' to '[9]', with a step of 3 "\ "(i.e. on images '[0]', '[3]', '[6]' and '[9]')."\n\ " - 'command[0--1:2]': Apply command only on images of the list with even indices. "\n\ " - 'command[0,2-4,50%--1]': Apply command on images '[0]', '[2]', '[3]', '[4]' and on the second half of "\ "the image list."\n\ " - 'command[^0,1]': Apply command on all images except the first two."\n\ " - 'command[name1,name2]': Apply command on named images 'name1' and 'name2'."\n\ \n\ "* Indices in selections are always sorted in increasing order, and duplicate indices are "\ "discarded. For instance, selections '[3-1,1-3]' and '[1,1,1,3,2]' are both equivalent to "\ "'[1-3]'. If you want to repeat a single command multiple times on an image, use a "\ "'repeat..done' loop instead. Inverting the order of images for a command is achieved by "\ "explicitly inverting the order of the images in the list, with command 'reverse[selection]'."\n\ "* Command selections '[-1]', '[-2]' and '[-3]' are so often used they have their own shortcuts, respectively "\ "'.', '..' and '...'. For instance, command 'blur..' is equivalent to 'blur[-2]'. "\ "These shortcuts work also when specifying command arguments."\n\ "* G'MIC commands invoked without '[selection]' are applied on all images of the list, i.e. the "\ "default selection is '[0--1]' (except for command ''input'' whose default selection is '[-1]'')."\n\ "* Prepending a single hyphen '-' to a G'MIC command is allowed. This may be useful to recognize "\ "command items more easily in a one-liner pipeline (typically invoked from a shell). "\n\ "* A G'MIC command prepended with a plus sign '+' does not act __in-place__ but inserts its result as one or "\ "several new images at the end of the image list."\n\ "* There are two different types of commands that can be run by the G'MIC interpreter:"\n\ " - __Built-in commands__ are the hard-coded functionalities in the interpreter core. They are thus compiled as "\ "binary code and run fast, most of the time. Omitting an argument when invoking a built-in command is not permitted, "\ "except if all following arguments are also omitted. "\ "For instance, invoking 'blur 1,,1' is invalid but 'blur 1' is correct. "\n\ " - __Custom commands__, are defined as G'MIC pipelines of built-in or other custom commands. "\ "They are parsed by the G'MIC interpreter, and thus run a bit slower than built-in commands. "\ "Omitting arguments when invoking a custom command is permitted. For instance, expressions "\ "`flower ,,,100,,2` or `flower ,` are correct. "\n\ \n\ "* Most of the existing commands in G'MIC are actually defined as __custom commands__. "\n\ "* A user can easily add its own custom commands to the G'MIC interpreter (see section "\ " ''Adding Custom Commands'' for more details). New built-in commands cannot be added (unless you modify the "\ "G'MIC interpreter source code and recompile it)." _section "Input/Output Properties" _text \ "* G'MIC is able to read/write most of the classical image file formats, including:"\n\ " - 2D grayscale/color files: `.png`, `.jpeg`, `.gif`, `.pnm`, `.tif`, `.bmp`, ..."\n\ " - 3D volumetric files: `.dcm`, `.hdr`, `.nii`, `.cube`, `.pan`, `.inr`, `.pnk`, ..."\n\ " - Video files: `.mpeg`, `.avi`, `.mp4`, `.mov`, `.ogg`, `.flv`, ..."\n\ " - Generic text or binary data files: `.gmz`, `.cimg`, `.cimgz`, `flo`, `ggr`, `gpl`, `.dlm`, `.asc`, "\ "`.pfm`, `.raw`, `.txt`, `.h`."\n\ " - 3D mesh files: `.off`, `.obj`."\n\ \n\ "* When dealing with color images, G'MIC generally reads, writes and displays data using the usual "\ "sRGB color space."\n\ "* When loading a `.png` and `.tiff` file, the bit-depth of the input image(s) is returned to the status."\n\ "* G'MIC is able to manage __3D mesh objects__ that may be read from files or generated by G'MIC commands.

"\ "These 3D representations can be then processed as regular images (see command ''split3d'' for accessing "\ "each of these 3D object data separately)."\n\ "* Be aware that usual file formats may be sometimes not adapted to store all the available image "\ "data, since G'MIC uses float-valued image buffers. For instance, saving an image that was "\ "initially loaded as a 16bits/channel image, as a `.jpg` file will result in a loss of "\ "information.

"\ "Dynamic arrays adapt their size to the number of elements they contain."\n\n\ "A dynamic array can be manipulated in a math expression, with the following functions:"\n\ "* 'da_size(_#ind)': Return the number of elements in dynamic array '[ind]'."\n\ "* 'da_back(_#ind)': Return the last element of the dynamic array '[ind]'."\n\ "* 'da_insert(_#ind,pos,elt_1,_elt_2,...,_elt_N)': Insert 'N' new elements 'elt_k' starting from index 'pos' "\ "in dynamic array '[ind]'."\n\ "* 'da_push(_#ind,elt1,_elt2,...,_eltN)': Insert 'N' new elements 'elt_k' at the end of dynamic array '[ind]'."\n\ "* 'da_pop(_#ind)': Same as 'da_back()' but also remove last element from the dynamic array '[ind]'."\n\ "* 'da_push_heap(_#ind,elt1,_elt2,...,_eltN)' and 'da_pop_heap(_#ind)' does the same but for a dynamic array viewed "\ "as a min-heap structure."\n\ "* 'da_remove(_#ind,_start,_end)': Remove elements located between indices 'start' and 'end' (included) "\ "in dynamic array '[ind]'."\n\ "* 'da_freeze(_#ind)': Convert a dynamic array into a 1-column image with height 'da_size(#ind)'."\n\ "* The value of the k-th element of dynamic array '[ind]' is retrieved with 'i[_#ind,k]' (if the element is a "\ "scalar value), or 'I[_#ind,k]' (if the element is a vector)."\n\n\ "In the functions above, argument '#ind' may be omitted in which case it is assumed to be '#-1'."\n\ "## Special operators:"\n\ "* ';': expression separator. The returned value is always the last encountered expression. "\ "For instance expression '1;2;pi' is evaluated as 'pi'."\n\ "* '=': variable assignment. Variables in mathematical parser can only refer to numerical "\ "values (vectors or scalars). Variable names are case-sensitive. Use this operator in conjunction with ';' to define "\ "more complex evaluable expressions, such as \n~~~\nt = cos(x); 3*t^2 + 2*t + 1\n~~~\n"\ "These variables remain __local__ to the mathematical parser and cannot be accessed outside the evaluated "\ "expression."\n\ "* Variables defined in math parser may have a __constant__ property, by specifying keyword 'const' before the "\ "variable name (e.g. 'const foo = pi/4;'). The value set to such a variable must be indeed a __constant scalar__. "\ "Constant variables allows certain types of optimizations in the math JIT compiler."\n\ \ "## Specific functions:"\n\ "* 'addr(expr)': return the pointer address to the specified expression 'expr'. "\n\ "* 'o2c(_#ind,offset)' and 'c2o(_#ind,x,_y,_z,_c)': Convert image offset to image coordinates and vice-versa. "\n\ "* 'fill(target,expr)' or 'fill(target,index_name,expr)' fill the content of the specified target "\ "(often vector-valued) using a given expression, e.g. `V = vector16(); fill(V,k,k^2 + k + 1);`. "\ "For a vector-valued target, it is basically equivalent to: "\ "`for (index_name = 0, index_name=0' (e.g., '46368' for 'N=24').

"\ "It is basically equivalent to: "\ "`for (iter_name = 0, iter_namebegin(foo = 0); ++foo\"')."\n\ "* 'copy(dest,src,_nb_elts,_inc_d,_inc_s,_opacity)' copies an entire memory block of 'nb_elts' elements starting "\ "from a source value 'src' to a specified destination 'dest', with increments defined by 'inc_d' and 'inc_s' "\ "respectively for the destination and source pointers."\n\ "* 'stats(_#ind)' returns the statistics vector of the running image '[ind]', i.e the vector "\ "`[ im,iM,ia,iv,xm,ym,zm,cm,xM,yM,zM,cM,is,ip ]` (14 values)."\n\ "* 'ref(expr,a)' references specified expression 'expr' as variable name 'a'."\n\ "* 'unref(a,b,...)' destroys references to the named variable given as arguments."\n\ "* 'breakpoint()' inserts a possible computation breakpoint (useless with the cli interface)."\n\ "* '_(comment) expr' just returns expression 'expr' (useful for inserting inline comments in math expressions)."\n\ "* 'run('pipeline')' executes the specified G'MIC pipeline as if it was called outside the currently evaluated "\ "expression."\n\ "* 'set(\\'variable_name\\',A)' set the G'MIC variable '$variable_name' with the value of expression 'A'. If 'A' is"\ " a vector-valued variable, it is assumed to encode a string."\n\ "* 'store(\\'variable_name\\',A,_w,_h,_d,_s,_is_compressed)' transfers the data of vector 'A' as a "\ "`(w,h,d,s)` image to the G'MIC variable '$variable_name'. Thus, the data becomes available outside the math "\ "expression (that is equivalent to using the regular command ''store'', but directly in the math expression)."\n\ "* 'get(\\'variable_name\\',_size,_return_as_string)' returns the value of the specified variable, as a vector of "\ "'size' values, or as a scalar (if 'size' is zero or not specified)."\n\ "* 'name(_#ind,size)' returns a vector of size 'size', whose values are the characters codes of the name of image "\ "'[ind]' (or default image selected if 'ind' is not specified)."\n\ "* 'correlate(I,wI,hI,dI,sI,K,wK,hK,dK,sK,_boundary_conditions,_is_normalized,_channel_mode,_xcenter,_ycenter,"\ "_zcenter,_xstart,_ystart,_zstart,_xend,_yend,_zend,_xstride,_ystride,_zstride,_xdilation,_ydilation,_zdilation)'"\ " returns the correlation, unrolled as a vector, of the `(wI,hI,dI,sI)`-sized image 'I' "\ "with the `(wK,hK,dK,sK)`-sized kernel 'K' (the meaning of the other arguments are the same as in command "\ "'correlate'). Similar function 'convolve(...)' is also defined for computing the convolution between 'I' and 'K'."\n\ \ "## User-defined macros:"\n\ "* Custom macro functions can be defined in a math expression, using the assignment operator "\ "'=', e.g. \n~~~\nfoo(x,y) = cos(x + y); result = foo(1,2) + foo(2,3)\n~~~\n"\n\ "* Trying to override a built-in function (e.g. 'abs()') has no effect."\n\ "* Overloading macros with different number of arguments is possible. Re-defining a previously defined macro with "\ "the same number of arguments discards its previous definition."\n\ "* Macro functions are indeed processed as __macros__ by the mathematical evaluator. You should avoid invoking them "\ "with arguments that are themselves results of assignments or self-operations. "\ "For instance, \n~~~\nfoo(x) = x + x; z = 0; foo(++z)\n~~~\n returns '4' rather than expected value '2'."\n\ "* When substituted, macro arguments are placed inside parentheses, except if a number sign "\ "'#' is located just before or after the argument name. For instance, expression \n"\ "~~~\nfoo(x,y) = x*y; foo(1+2,3)\n~~~\n "\ "returns '9' (being substituted as '(1+2)*(3)'), while expression \n~~~\nfoo(x,y) = x#*y#; foo(1+2,3)\n~~~\n "\ "returns '7' (being substituted as '1+2*3')."\n\ "* Number signs appearing between macro arguments function actually count for __empty__ separators. They may be used "\ "to force the substitution of macro arguments in unusual places, e.g. as in \n~~~\nstr(N) = ['I like N#'];\n~~~\n"\ "* Macros with variadic arguments can be defined, by specifying a single argument name followed by `...`. "\ "For instance,\n~~~\nfoo(args...) = sum([ args ]^2);\n~~~\n "\ "defines a macro that returns the sum of its squared arguments, so `foo(1,2,3)` returns `14` and "\ "`foo(4,5)` returns `41`.\n"\ \ "## Multi-threaded and in-place evaluation:"\n\ "* If your image data are large enough and you have several CPUs available, it is likely that the math expression "\ "passed to a 'fill', 'eval' or 'input' commands is evaluated in parallel, using multiple computation threads."\n\ "* Starting an expression with ':' or '*' forces the evaluations required for an image to be run in parallel, "\ "even if the amount of data to process is small (beware, it may be slower to evaluate in this case!). "\ "Specify ':' (rather than '*') to avoid possible image copy done before evaluating the expression "\ "(this saves memory, but do this only if you are sure this step is not required!)"\n\ "* Expression starting with '+' are evaluated in a single-threaded way, with possible image copy."\n\ "* If the specified expression starts with '>' or '<', the pixel access operators 'i()', 'i[]', 'j()' and 'j[]' "\ "return values of the image being currently modified, in forward ('>') or backward ('<') order. "\ "The multi-threading evaluation of the expression is disabled in this case."\n\ "* Function 'critical(expr)' forces the execution of the given expression in a single thread at a time."\n\ "* 'begin_t(expr)' and 'end_t(expr)' evaluates the specified expression once for each running thread "\ "(so possibly several times) at the beginning and the end of the evaluation procedure."\n\ "* 'merge(variable,operator)' tells to merge the local variable value computed by threads, with the specified "\ "operator, when all threads have finished computing."\n\ "* Expressions 'i(_#ind,x,_y,_z,_c)=value', 'j(_#ind,x,_y,_z,_c)=value', 'i[_#ind,offset]=value' and "\ "'j[_#ind,offset]=value' set a pixel value at a different location than the running one in the image '[ind]' "\ "(or in the associated image if argument '#ind' is omitted), either with global coordinates/offsets "\ "(with 'i(...)' and 'i[...]'), or relatively to the current position `(x,y,z,c)` (with 'j(...)' and 'j[...]'). "\ "These expressions always return 'value'." _section "Adding Custom Commands" _text \ "* New custom commands can be added by the user, through the use of G'MIC __custom commands files__."\n\ "* A command file is a simple text file, where each line starts either by "\ "\n~~~\ncommand_name: command_definition\n~~~\n or \n~~~\ncommand_definition (continuation)\n~~~\n"\n\ "* At startup, G'MIC automatically includes user's command file '$HOME/.gmic' (on __Unix__) or "\ "'%USERPROFILE%\\user.gmic' (on __Windows__). The CLI tool 'gmic' automatically runs the command "\ "'cli_start' if defined."\n\ "* Custom command names must use character set `[a-zA-Z0-9_]` and cannot start with a number."\n\ "* Any `# comment` expression found in a custom commands file is discarded by the G'MIC parser, "\ "wherever it is located in a line."\n\ "* In a custom command, the following '$-expressions' are recognized and substituted:"\n\ " - '$""\*' is substituted by a verbatim copy of the specified string of arguments "\ "(do not include arguments set to default values)."\n\ " - '$\"*\"' is substituted by the sequence of specified arguments, separated by commas ',', "\ "each being double-quoted (include arguments set to default values)."\n\ " - '$""#' is substituted by the maximum index of known arguments (either specified by the user or set to a default "\ "value in the custom command)."\n\ " - '$""[]' is substituted by the list of selected image indices that have been specified in the command "\ "invocation."\n\ " - '$""?' is substituted by a printable version of '$""[]' to be used in command descriptions."\n\ " - '$i' and '${i}' are both substituted by the `i`-th specified argument. Negative indices such as '${-j}' are "\ "allowed and refer to the `j`-th latest argument. '$""0' is substituted by the custom command name."\n\ " - '${i=default}' is substituted by the value of '$i' (if defined) or by its new value set to 'default' otherwise "\ "('default' may be a `$-expression` as well)."\n\ " - '${subset}' is substituted by the argument values (separated by commas ',') of a specified argument subset. "\ "For instance expression '$""{2--2}' is substituted by all specified command arguments except the first and the last "\ "one. Expression '$""{^0}' is then substituted by all arguments of the invoked command (eq. to '$""*' if all "\ "arguments have been indeed specified)."\n\ " - '$""=var' is substituted by the set of instructions that will assign each argument '$i' to the named variable "\ "'var$i' (for i in '[0...$""#]'. This is particularly useful when a custom command want to manage variable numbers "\ "of arguments. Variables names must use character set `[a-zA-Z0-9_]` and cannot start with a number."\n\ \n\ "* These particular `$-expressions` for custom commands are __always substituted__, even in "\ "double-quoted items or when the dollar sign '$' is escaped with a backslash '\\$'. To avoid substitution, place an "\ "empty double quoted string just after the '$' (as in '$\"\"1')."\n\ "* Specifying arguments may be skipped when invoking a custom command, by replacing them by commas ',' as in "\ "expression \n~~~\nflower ,,3\n~~~\n Omitted arguments are set to their default values, which must be thus explicitly "\ "defined in the code of the corresponding custom command (using default argument expressions as '$""{1=default}')."\n\ "* If one numbered argument required by a custom command misses a value, an error is thrown by the G'MIC "\ "interpreter."\n\ "* It is possible to specialize the invocation of a '+command' by defining it as "\ "\n~~~\n+command_name: command_definition\n~~~\n"\ "* A +-specialization takes priority over the regular command definition when the command is invoked with a "\ "prepended '+'."\n\ "* When only a +-specialization of a command is defined, invoking 'command' is actually equivalent to '+command'." _section "List of Commands" _text \ "All available G'MIC commands are listed below, by categories.

Image Gallery

"\n\n\ "

This gallery gives a quick overview of the kind of features and generic filters available in the "\ "G'MIC open-source image processing framework.

"\n\ "

All the images below have been processed by the CLI interface "\ "gmic"\ " of G'MIC, from a set of initial 2D color images."\n\ " Click on an image to enlarge it and display the G'MIC command-line "\ "used for the processing (note: to reproduce this, you may have to escape some characters, "\ "according to the type of shell you use!).

"\n\ "

Remember, G'MIC lets you define your own image pipelines through"\ "custom command files."\n\ " Your custom filters can be easily added afterwards in the plug-in for "\ "GIMP or Krita.

"\n\ "

For more details, visit the tutorial pages as well as the "\ "technical reference to get a full documentation on this "\ "software.
