- PMBC??? Lossless image compression? I like the sound of that. Up until I
- found out that JPEG is not lossless, even at 100% quality, I have been using it
- to store those unwieldy 24-bit pictures. I don't want to save them like that
- anymore because if I succesively load and save in JPEG as I'm working on an
- image, it will slowly start to degrade. When I zoom in, I can see the damage
- that JPEG has done, however slight.
-
- I do love that JPEG saves files 20% or more of the original size, but now I
- want lossless, faster compression. What kind of compression ratio could I
- expect to get out of PMBC? 800K down to 80K? If I'm going to spend the time to
- compress/decompress, I want to be able to get a decent compression out of it,
- or it's not worth the time invested.
-
- Are there any other lossless 24-bit formats out there? How does LZW
- compression compare (or is that the same as JPEG)?
-
- Thanks.
