I got the below output when tried to compare 2 png images.
Cannot read: format 'png' not supported - formats bmp, ico, pnm, raw, sgi, tga available for reading
Could you please help me to know the reason.
Comment on Re^2: compare images with perl 5.6 or 5.8
The error means that when you compiled Imager, you didn't have libpng installed on your system, so png support was skipped. Install the full libpng ( some distros separate the development headers into something like libpng-devel. Just google
for libpng, compile it, install it, then rebuild Imager.
