WebP Import / Export
December 14, 2011 - 03:24 — george_edison
This plugin makes it possible to load and save files using the new WebP image format. (http://code.google.com/speed/webp/)
When saving images in this format, you will be able to specify a quality factor that can range from 0 to 100. The higher the number, the larger the file produced and the better the quality of the image.
Since at the time of writing there were no provisions for alpha channels in WebP images, all images loaded with this plugin will not have an alpha channel. As well, when saving images, you will be prompted to flatten the image if it contains an alpha channel.

Compiling under Mac OSX
Hi guys
I have tried to compile your Plugin under Mac OSX, but I fail.
Gimp has been installed through macports.
To compile the plugin I tried to follow the Readme file in the source folder but the first error I ran is that
gimptool-2.0 --install file-webp.c
des not work. It must be
gimptool-2.0 --install scr/file-webp.c
maybe you whant to chance the readme herer in the future.
But when I start it I get the error:
Undefined symbols for architecture x86_64:
"_read_webp", referenced from:
_run in file-webp-wWF6Se.o
"_export_dialog", referenced from:
_run in file-webp-wWF6Se.o
"_write_webp", referenced from:
_run in file-webp-wWF6Se.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have found out that this has something to do with the linking of the gcc or clang compiler (If I understand the google posts correctly) but I do not understand what I have to chance now to make it work.
It would be nice if somebody can help me with this.
regards
Size related issue
First, thanks to george_edison for the plugin.
I'm running into a size related problem with the following configuration.
Windows 7 64 bit
Gimp 2.8.0
64 bit version of Plugin
On 12MP images (4000x3000) the plugin works fine. But on a stitched 28.4MP (11336x2507) image the save feature would not work with the quality set to 100.
The GIMP Message is:
----------------------------------------------------------------
Saving 'Path:\Filename' failed:
WebP image plug-in could not save image.
----------------------------------------------------------------
Has anyone else seen this?
I Can Reproduce This
I was able to reproduce the error you described using Gimp 2.8 on Windows 8 x64. I'm afraid I have no idea what would cause this to fail - it might be a limitation of the Gimp or perhaps a limitation of the WebP encoder that the plugin uses.
Update for 2.8?
Any chance you'll have the time to update this plugin to work with GIMP-2.8?
Gimp 2.8 Support Complete
This plugin has been updated for Gimp 2.8 now. I have created installers for Windows now so installing the plugin is incredibly simple. Just download the ZIP file for your CPU architecture (download the 32-bit version if you're not sure what architecture you have) and launch the installer.
It works on 2.8 !
did you tried before ask a update ? On my computers works well with gimp- 2.8rc1
How to install.
Please don’t make it harder for future generations!
Dump the exe file here C:\Program Files\GIMP-2.0\lib\gimp\2.0\plug-ins and you are done.
Don’t try executing the EXE waste of time…
If the directory is different just search inside GIMPs main folder a folder named “plug” with ought quotation marks dump the exe inside it.
Here is the codec for your windows to be able to open the* .webp files you make with GIMP.
http://code.google.com/speed/webp/docs/webp_codec.html
(If I had any mistakes in English, cope with it :D, wasted 2 hrs of my life trying to figure out how to install this thing :SSSSSS) I’m a beginner in GIMP and looks like it’s not user friendly… But I’ll give it another chance!
Installation Now Automated
This is no longer necessary - I have created installers for both 32 and 64-bit editions of Windows. The installer will take care of everything for you now so you don't have to manually copy anything anywhere.
How to install better
the previous suggestion would somehow works but is not the best solution:
It is messy adds custom plugins in the place reserved for build in plugins
The correct place is C:/ Users/your-name-here/.gimp-2.6/plug-ins
(for 7 and Vista, for xp replace Users with "Documents and Settings")
sources?
A32 bit Windows executable is not very useful on my 64 bit Linux system. Can I find the sources somewhere, so I can compile it for my system?
