(...) Is there some other way to compress JPG files, besides lowering the quality? Whenever I save a JPG file with 100% accuracy, the saved file is huge (ie, about the same size as a similar BMP file). (...) I've never heard of any kind of (...) (25 years ago, 28-Mar-00, to lugnet.cad.dev)

(...) This problem is why I chose PNG. It compresses flat shaded images quite well and still retains the true color pixels. My comprehensive testing of one sample image (the one on the LdGLite web page) put the PNG file at about half the size of the (...) (25 years ago, 28-Mar-00, to lugnet.cad.dev)

(...) Well, it's not *that* big'o'deal: GIF is restricted to 256 colors. If you convert down to 256 colors, will PNG give compression on par with GIF? If it doesn't, you can always look into BMP/RLE. FYI, here are some links into the MS (...) (25 years ago, 28-Mar-00, to lugnet.cad.dev)

(...) From what I've seen PNG gives BETTER compression than GIF for flat shaded ldlite type images, and as far as I can tell it only does 32bpp true color. I put a sample PNG on the ldglite web page if you want to try converting to various formats (...) (25 years ago, 29-Mar-00, to lugnet.cad.dev)

(...) I didn't see it, but I didn't look really hard at the windows specific code since I'm bypassing it for something more portable. If you still have the code I could try to paste it in with the other two formats. Don (25 years ago, 29-Mar-00, to lugnet.cad.dev)
