--- Comment #10 from Tomaz Vajngerl <qui...@gmail.com> --- (In reply to V Stuart Foote from comment #7) > We do keep the original 1bpp image, placing it in the ODF archive's Pictures > directory. Yes, the original is available, but you don't put PNG inside PDF - so reading again would again produce a 8-bit RGB Bitmap. > For now though, the resulting PDF is simply larger bcz of embedding an 8bpp > bitmap into a stream. But do we need to generate PDF with 1bpp images? No - I don't think so. > Other than size of the PDF what is the justification?

The 8bpp grayscale will look better than 1bpp. It will look exactly the same - no matter if it's 1bpp or 8bpp. > And in this sample we're working with the full image on document > canvas--what happens when the original image has been masked, clipped or > otherwise edited (i.e. image filtered). An 8bpp or 24bpp image is going to > be required then, right? If the Bitmap is changed in any way (resized for example), it's converted to 24-bit RGB. If it's just metadata (crop for example) then it depends - not sure what happens with PDF. > So unless this is really easy, then reasonable to => WF Well, it's an issue, but low priority. -- You are receiving this mail because: You are the assignee for the bug.
