I've put the down as an "enhancment" although I consider it to be a defect - it's certainly a wobbler and defect in the thinking if not the product. JPEG images included in writer documents are output to the printer using LZW compression. (The images is read via the psp_lzwfilter procedure, currentfile /ASCII85Decode filter /LZWDecode filter.) This is wasteful as a JPEG image can be put in the PostScript and the DCTDecode filter used to read. There is a reason I choose to use JPEG to compress my images in the first place. Had I though LZW would be the best, I would have used PNG to save the image. Attached are some examples that show the problem and demonstrate how to use JPEG data raw in PostScript. Note when LZW compressed the image include is 17.6 times bigger than is should be - a non-trivial amout. otz.bunny.jpeg - The picture otz.bunny.eps - The same picuture as an EPS, uses the actual JPEG data and DTCDecode otz.bunny.jpeg.sxw - Writer doc using the JPEG (JFIF) otz.bunny.eps.sxw - Writer doc using the EPS otz.bunny.jpeg.ps - print output from JPEG - BLOAT otz.bunny.eps.ps - print output using the EPS
