Have you tried http://hackage.haskell.org/cgi-bin/hackage-scripts/package/pngload ? Hi Mark,
I just did:
import Codec.Image.PNG
png_file_to_2d_array file = do either_error_string_or_png <- loadPNGFile file either (\s -> error $ "(png_file_to_2d_array) " ++ s) (\png -> putStrLn (show (dimensions png)) ) either_error_string_or_png
and then calling it gives:
*** Exception: (png_file_to_2d_array) failed to parse chunk "IHDR", (line 1, column 1): unexpected 0x0 expecting valid colorType: supported Ct2,Ct6
Testing this code with the PNG file from [1] gives me (png_file_to_2d_array) "PNG_transparency_demonstration_2.png" (line 1, column 1): unexpected 0x2d I guess that proves that it's not just you, but not much else.
