I agree about avoiding BMP files - they're HUGE, expecially when
you import them into a M$ word file. I'm in the process of
plaigarizing some manuals, and one of the things they have
is "Visio," which, as it turns out, is a dream for doing
flowcharts and stuff; anyway, when I update a Visio flowchart,
it gives me a "save as" drop-down box with about a dozen different
formats, one of which is .bmp, and another is .wmf. So, I'm
looking at this chart, and the doc. it's supposed to go in
doesn't read .vsd files, so I export it as a .bmp file. Then
go back to word, insert the picture, and get a 360K document.
So I go back to Visio, save as a .wmf, import the .wmf into the
word doc (replacing the .bmp), and the file is like 16K!
I have some OCR software that will ONLY accept uncompressed
TIFF files (or raw scanner, but that's a pain in the you-know-
what); I haven't compared bmp to tif files as far as size, I've
just usually used whatever works.
My stock answer is use .gif for line art and .jpg for the
nudies. ;-} AIUI, .gif compresses the best, losslessly, albeit
I haven't actually bothered to do any comparisons to compressed
tiff. BMP files are ridiculous, and of course everyone knows
whom we should thank for that piece of work. ;=}
