I've configured PHP with gd, zlib and png. phpinfo() shows gd and zlib as supported but not png.
While calling ImageCreate() i did not receive any error, but ImagePNG() reports an error. I sent the header image/png of course. Png was installed correctly ('make test' worked fine).
While configuring i received in output:
checking for gdImageWBMP in -lgd... yes
Should I receive similiar for gdImagePNG?
Where could I make a mistake?
I also tried ImageWBMP(), it didn't report an error so gd is working fine. (WBMP image does not appear, thats a subquiestion: can I display WBMP in my (not WAP) browser?)
Thanks for your help!
