Hiya,

'pngcrush' (commandline option) can do this as well as 'imagemagic' (also commandline).

imagemagick: convert pic.png -background white -flatten +matte pic_new.png

Unless what you want to do is get it into indexed (palette) mode and remove the alpha channel from there.

png2pdf might be an option, it can take care of the alpha channel and give you a pdf, which you can embed into a pdf
(http://png2pdf.sourceforge.net)

Cheers,

Luis.

Hi Trevor,

if you export image as paint, then it is exported in ppm (portable pixelmap) format (uncompressed RGB without alpha channel). You can load ppm files with Rev too.

Hi Viktoras,

Thanks for the suggestion. I need PNG though as the files are for use in the Quartam PDF library.

Regards,
