Is there an easy way to convert from ARGB to ACMYK bitmaps while preserving the Alpha throughout process? Whenever I change the colorspace of the bitmap to ACMYK and save it as a PDF the image is 'flattened' and no Alpha remains... I have considered that the problem might be the PDF file format, but haven't done enough testing to conclude this. Hope you can help Thanks!

Hello, PDF format doesn't support CMYK with alpha. Alpha channel is discarded during saving to PDF format. Only TIFF format supports ACMYK pixel format for saving.
