Advanced image handling in TYPO3 CMS uses the command line tools GraphicsMagick or ImageMagick. The tools need to be configured correctly depending on the version that is available on the system.
This module detects the available image handling versions and sets the system accordingly. If everything is correctly set up the image tests of the install tool section "Test setup" should be fine.
If ImageMagick or GraphicsMagick executables are located at some not standard place, add the absolute directory name here.
