I want to create a PNG file from a System.Drawing.Bitmap with the colours defined using CMYK.
I can create the PNG OK but how do I define ‘with CMYK’ ?
I’ve looked at the encoderparameters argument to the save method but it seems to me they don’t cover what I need ?
Any pointers/samples appreciated.
thanks
The PNG format was designed for transferring graphics for display on computer screens. PNG files may only transfer grayscale or RGB/RGBA image data; you can’t have a CMYK PNG file: http://www.w3.org/TR/2003/REC-PNG-20031110/#11IHDR
