graphic file format, which?
Which graphic file format is most likely to be readable on any modern operating system--.tif, .jpg, .bmp, what? (I don't want to save and email a raw file.) If .tif, then what flavor? (My scanner program, which I have to run out of Windows, since I can't get the scanner to work right in Linux, has got some formats that I never even heard of!) Oh, the scanner is fussy in Windows XP, also. Some of the programs it should work with, it won't. --doug

'Not surprised at that. I'd suggest jpg for any graphic file that has to be easily read by other systems. It's a lossey format, but sometimes you don't have a choice. I import Canon RAW files and save as tifs, then reduce to no larger than 1024x? and save as jpg for an image to send "out."

jpeg, to use in email. It looses some information, but you can adjust how much (and see the result) with gimp. If size is not important, but quality is, send as png. -- Cheers, Carlos Robinson

More precisely, for photographs or other imagery that has a wide range of colors following relatively smooth transisitons, jpeg's default compression scheme works very well. If you have sharp color transitions - like line art or something with text in it - or if you have an image that uses few color, you will get better results with a bitmapped format. I think that png is very good for that use, as long as you have a good png program. If you need to keep quality over size, png is always a better choice. It's worth noting that most of the Adobe programs, etc, do a horrible job of supporting png compression. If you grab something like pngcrush, etc, and run it on the png images your scanning program generates, you'll probably save some space. Alternativey, the Gimp supports png compression well, so it might be worthwhile to get the win32 version of the Gimp and either use it to TWAIN accuire scans, or scan to tiff and convert to png with Gimp. --Danny
