convert, libpng and "Ignoring incorrect gAMA value" message
Posted: 2013-04-29T03:53:38-07:00
Hi all,
I use convert in FVWM-Crystal with a bash script to generate the icons used into the application menu. Those icons are generated from the application provided icons. fvwm-crystal.generate-menu
The call to convert is very basic:
"input_file" can be any kind of GNU/Linux icon files.
At Fvwm-Crystal restart, some of the converted files gave me warnings like:
I try to run convert on the generated files and most of the warnings was gone. After 2 more times, all warnings was gone. My fix for Fvwm-Crystal script is to run convert 3 more times on the converted files, and it seam to work very well in practice:
Is it some way to simplify this, some command I can use instead of those 4 convert calls that will convert the original icon files and give a "clean" result?
