Correct. Can someone outline what is required for including a GIF image into a PDF document ... I need to know the appropriate objects plus what 'parts' of the GIF need to be included into the stream. Read the headers, then decompress the GIF file. Look into the situation with the Unisys patent on LZW - you may need to pay a license to write this code. Extract the colour palette to build an Indexed colour space. Then, recompress the GIF file using Flate encoding. Aandi To change your subscription: http://www.pdfzone.com/discussions/lists-pdfdev.html
