gebo-imagemagick-action v0.0.9

gebo-imagemagick-action

An ImageMagick-dependent gebo action image converter

ImageMagick

Version 6.7.7-10 was already installed in my Ubuntu 14.04 distribution. I have found, however that unit tests pass inconsistently, especially when converting BMPs to PNGs or GIFs. The following command will install version 6.7.7-10 (as of 2014-10-4). It appears to work even though the tests report errors.

sudo apt-get install imagemagick

Compiling from source

Compiling the source seems to eliminate the BMP-to-GIF errors, though the PNGs remain when testing the library functions exclusively. When all tests are run, the problems disappear.

sudo apt-get remove imagemagick

To install the current 6.8.9-8 from source:

sudo -i
cd
apt-get install build-essential checkinstall && apt-get build-dep imagemagick -y
wget http://www.imagemagick.org/download/ImageMagick-6.8.9-8.tar.gz
tar xvf ImageMagick-6.8.9-8.tar.gz
cd ImageMagick-6.8.9-8/
./configure --prefix=/opt/imagemagick-6.8 && make
checkinstall
ln -s /opt/imagemagick-6.8/bin/animate /usr/bin/
ln -s /opt/imagemagick-6.8/bin/compare /usr/bin/
