HI, I installed imageMagick 5.5.7 in my server and when i use a PNG not work.
when I try convert -list Format
I have this result :

PNG* --- Portable Network Graphics
See http://www.libpng.org/ for details about the PNG format.
The PNG 1.2 specification is available there and at
ftp://swrinde.nde.swri.edu/pub/png/documents/.
PNG24* --- 24-bit RGB PNG, opaque only
PNG32* --- 32-bit RGBA PNG, semitransparency OK
PNG8* --- 8-bit indexed PNG, binary transparency only

Thanks,

Did you build ImageMagick from source? If so either the PNG delegate library or development header files were not available when ImageMagick was configured. After you run the configure script check config.log to determine why the PNG delegate library failed to validate and fix the problem.

If your version of ImageMagick came from a binary distribution it simply means that whomever built it did not include PNG support.

yes in the log he don't find png.h
How can i install png.g?
thanks
