Save for the web in gimp
If you are like me, who migrated from Photoshop to gimp, you may miss the "save for the web" option that Photoshop has.
There is a plugin for gimp that will do almost exactly the same task. However, it seems that has not been distribuited for earlier versions. I couldn't find any installable package for Ubuntu earlier than version 5.0.
According to some post in a fourum:
"There's currently a "save for web" option in GIMP 2.3.15 unstable release that works quite nicely.". However, I have gimp 2.4.5-1 and there is not such option available.
Affortunately, there is still available the code at the "Gimp Plugin Registry":
http://registry.gimp.org/node/33if doesn't work, you can download it from my server:
gimp-save-for-web-0.28.5.tar.bz2In order to successfully compile that plugin, you need pkg-config, libgimp-2.0-dev, and its dependences (which are many dev libraries). In total you require to download, and install 38MB.
The compilation was smooth and without any errors.
To facilitate their installation, I prepared the .deb packages for Ubuntu Hardy, both versions, x86 and amd64-bit versions. You can download them here:
gimp-save-for-web_0.28.5-1_i386.debgimp-save-for-web_0.28.5-1_amd64.debIn order to install the one for your Ubuntu version, just download it and run:
$ sudo dpkg -i name_of_file.deb
Here are some of the screenshots of the "save for the web" plugin in my linux gimp:
