Actual Results: libpng error: Application uses deprecated png_write_init() and must be recompiled. gif2png: libpng returns fatal error condition Expected Results: creates efflogo.png Additional info:
That's gif2png's fault, not libpng's (it's using an obsolete function that has been deprecated since libpng 0.9). gif2png is not a part of libpng, and not shipped with Red Hat Linux, so there's nothing we can do about it. Recommendations: 1) Check wherever you got gif2png - maybe they've released a new version that fixes this problem. 2) Use ImageMagick's convert tool instead (syntax: convert filename.gif filename.png). It is included in Red Hat Linux, so you don't need a new download.
