HOWTO:Add WebP (weppy) support to GIMP.

[ron999]

I used this method with Ubuntu Lucid Lynx 10.04 and GIMP 2.6.8.

First install some packages.
Paste this single command:-

sudo apt-get install \
build-essential \
checkinstall \
gimp

Then compile and install the WebP library libwebp.
Paste this single command:-

cd ~/ && \
wget http://webp.googlecode.com/files/libwebp-0.1.2.tar.gz && \
tar -xvf libwebp-0.1.2.tar.gz && \
cd libwebp-0.1.2 && \
./autogen.sh && \
./configure && \
make && \
sudo checkinstall --pakdir "$HOME/Desktop" --pkgname libwebp \
--pkgversion 0.1.2 --backup=no --default && sudo ldconfig

When it's finished...
check that libwebp is installed OK with this command:-

cwebp -version

ron@ubuntu:~$ cwebp -version
0.1.2

Now to fix GIMP.
The WebP plugin is from here:- http://registry.gimp.org/node/25366
Paste this single command:-

cd /tmp && \ 
export LIBS=-lwebp && \
wget http://registry.gimp.org/files/file-webp.tar_0.gz && \
tar -xvf file-webp.tar_0.gz && \
gimptool-2.0 --install file-webp.c

That's it.

When you start GIMP it should be able to open webp files.
And also Save As... WebP image (*.webp)

P.S.
How to revert changes.

To uninstall libwebp use Synaptic Package Manager.

To un-patch GIMP?
Delete the hidden folder /home/user/.gimp-2.6 then re-start GIMP.

That's great! (And I'm not just saying that because I wrote the plugin )

But there is a much easier way to install the plugin. I have setup a PPA on Launchpad that contains the packages libwebp and gimp-webp. You can find the PPA here: https://code.launchpad.net/~george-e.../+archive/webp

After adding the PPA, it's just a matter of:

sudo apt-get update ; sudo apt-get install gimp-webp

This is really amazing. I appreciate this. Thank you.

Using GNU/Linux Mint 14 based on GNU/Linux Ubuntu quantal 12.10.

Adding PPA repository, update and install... :

# apt-add-repository ppa:george-edison55/webp 
# apt-get update
# apt-get install gimp-webp

A problem stay ... The plugin file of gimp-webp is in /lib/gimp/2.0/plug-ins folder "instead"(?) of /usr/lib/gimp/2.0/plug-ins

The ("bad"/"trivial") solution is to copy the file in "good" folder :

# cp /lib/gimp/2.0/plug-ins/file-webp /usr/lib/gimp/2.0/plug-ins/

Is this problem known ?
