Root element defining a composition of one or several pages.
Define the outline / bookmarks of the document, typically the
structure of pages. But bookmarks may also point to particular
elements in a page.
Recursive list of OutlineItem.
An OutlineItem may be final or a parent of child OutlineItem.
If the OutlineItem has children, the open attribute controls whether
the children list must be folded or not.
An OutlineItem may have zero, one or several acssociated actions.
User visible name of the outline item.
Whether children outline items should be unfolded.
Abstract action element type
Abstract action element
Goto a destination page.
The x1, y1, x2, y2 attributes
may also be defined to zoom-in on a particular area of the page.
Turn all layers on or off.
Later SetAllLayersStateAction/SetLayerStateAction might change this state.
Turn a specific layer on off.
Later SetAllLayersStateAction/SetLayerStateAction might change this state.
Execute a Javascript action.
See https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/js_api_reference.pdf
The script must be put as the content of the element.
The XMP payload must be serialized in a XML-escaped way
Hierarchical definition of layers ("Optional Content Group" in PDF parlance)
Common to all pages, but their visibility in the layer tree can
be controlled with the displayOnlyOnVisiblePages attribute.
Whether to list, in the layer tree, layers that are referenced
by at at least one currently visible page(s).
Default is false, that is the layers are always listed.
Define a Layer ("Optional Content Group" in PDF parlance)
Arbitrary id, unique to the layer. Will be cross-referenced by
IfLayerOnType#layerId to define conditional visibility.
User visible name
Arbitrary id defining a group of mutually exclusive layers.
Layers referencing to the same #mutuallyExclusiveGroupId value
will be mutually exclusive.
Arbitrary id, unique to the page. Required if the page must
be referenced by a OutlineItem.
CRS WKT string, or EPSG:XXXX code.
Define the viewport where georeferenced coordinates are
available.
If not specified, the extent of BoundingPolygon will be used instead.
If none of BoundingBox and BoundingPolygon are specified,
the whole PDF page will be assumed to be georeferenced.
Define a polygon / neatline in PDF units into which the
Measure tool will display coordinates.
If not specified, BoundingBox will be used instead.
If none of BoundingBox and BoundingPolygon are specified,
the whole PDF page will be assumed to be georeferenced.
Those points define the mapping from PDF coordinates to
georeferenced coordinates. At least 4 of them must be
provided. They do not need to form a rectangle neither in
PDF coordinate space nor in georeferenced coordinate space.
However if the georeferenced area is referenced to by content,
they must be evaluated to a geotransform, without rotation
or shearing.
ID that can be referred to to automatically place content.
The georeferencing area ca be referenced to, only if the
control points define an affine geotransform, without rotation
or shearing, from PDF coordinate space to georeferenced
coordinate space.
ISO-32000 extension format is the georeferencing format
recognized by the Measure / Geographic location tool of Acrobat reader.
OGC Best Practice format is the georeferencing format
recognized by the Terrago Toolbar.
It seems that within a PDF file,
there should be only georeferenced areas encoded with the
OGC Best Practice so that the Terrago Toolbar accepts to
read them.
Defines the data axis to SRS axis mapping. List of
comma-separated axis number (starting at 1).
Used to interpret the GeoX and GeoY attribute meaning.
If not specified, the traditional GIS order is assumed.
x2 must be > x1 and y2 > y1
X value of the control point expressed in the SRS
Y value of the control point expressed in the SRS
Sequence of raster, vector, labels, content from other PDF document,
or conditionalized content of any of the above types.
The content is drawn in the order it is mentioned, that is the
first mentioned item is drawn first, and the last mentioned item
is drawn last.
Insert the content stream of the (first page of the) PDF, together with
its resources, without any extra rasterization.
Optional content groups or georeferencing potentially found in the
PDF to insert are ignored.
The dimensions of the inserted PDF are assumed to be the same
as the PDF where it is inserted.
Insert raster (or rasterized) content from a GDAL dataset.
There are two modes:
- one where the raster potential georeferencing is completely ignored,
and the image is put at the specified PDF coordinates.
I which case , x1, y1, x2, y2 are in PDF coordinate units and represent the
area where the image will be stretched. If not specified,
the whole PDF page is occupied.
x2 must be > x1 and y2 > y1.
- another one, when the georeferencingId attribute is defined, and
reference a georeferenced area. In that case, the raster geotransform
will be used to correctly place it in the georeferenced area.
GDAL dataset name
References a georeferenced area in the same page
through its Georeferencing#id
Only applies when method=JPEG.
If not specified, if the source raster is a JPEG file, its
codestream will be used directly. Otherwise, the image will
be compressed with a quality of 75%.
Only applies when method=DEFALTE
Insert vector content from a OGR dataset.
There are two modes:
- The coordinates of the vector features must be in PDF coordinate units.
This is when the georeferencingId attributes is not set.
- another one, when the georeferencingId attribute is defined, and
reference a georeferenced area. In that case, the vector georeferenced
coordinates will be used to correctly place it in the georeferenced area.
Note: OGR Feature Style strings containing a LABEL tool will not work with
this element, to display labels use a VectorLabel element instead.
OGR dataset name
OGR layer name
References a georeferenced area in the same page
through its Georeferencing#id
Whether objects should be drawn or not
Name of the attribute whose value is used to create a hyperlink
String overriding per-feature style
The LogicalStructure element should be put when the features
of the layer should be written in the logical structure of the
document, and thus visible in the "Model Tree" of Acrobat reader.
By default, all OGR fields are included.
Whether all fields should be excluded, but the one(s)
potentially mentioned in IncludeField.
Name of OGR field to include.
Whether all fields should be included, but the one(s)
potentially mentioned in ExcludeField.
Name of OGR field to exclude.
Name of the layer that will appear in the PDF reader.
If not specified, this will be the OGR layer name.
Name of the OGR field whose value should be display for each
feature in feature tree of the PDF reader.
If not specified, this will "feature{FID}".
Insert text labels for features from a OGR dataset.
The features must be associated with a OGR Feature Style string with
a LABEL tool.
Only LATIN-1 characters will be correctly output.
There are two modes:
- The coordinates of the vector features must be in PDF coordinate units.
This is when the georeferencingId attributes is not set.
- another one, when the georeferencingId attribute is defined, and
reference a georeferenced area. In that case, the vector georeferenced
coordinates will be used to correctly place it in the georeferenced area.
OGR dataset name
OGR layer name
References a georeferenced area in the same page
through its Georeferencing#id
String overriding per-feature style
Blend mode as defined in PDF reference version 1.7
page 520, Table 7.2 "Standard separable blend modes".
Conditionalize content display to the On status of a layer.
IfLayerOn elements can be nested. And in general, the nesting used
to define the layers should be used to define the conditional
content too, because toggling off a upper-level layer in Acrobat
does not change the state of its children.
For example:
<Layer id="A" name="A">
<Layer id="A.1" name="A.1""></Layer>
</Layer>
<IfLayerOnType layerId="A">
<IfLayerOnType layerId="A.1">
....
</IfLayerOnType>
</IfLayerOnType>
Should reference a Layer#id attribute.
