    Question

    I was thinking, im kinda playing around with a paint program, is it possible to save a picture as your own type of format, that would be SMALLER (in KB) thank your average .bmp .jpg .gif ect?? If not, what is the smallest type i can save it as? thanks a bunch!

    A standard GIF is probably the smallest (but low quality) and a Bitmap is the largest (but with high quality). VB can only save in Bitmap format. If you want to save in a different format, you'd have to write your own code to do it or get a 3rd party control.

    Jpg's are usually smaller, but actually that depends on the detail of the image, a Gif is composed of 256 colors and isn't affected but a jpg would get lower quality except if you use a lower compression level.

    If you want i can send you the source code to save a jpeg image
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
    To throw away OOP for low level languages is myopia, to keep OOP is hyperopia. To throw away OOP for a high level language is insight.

    ummmmm. JPG's are the smallest, but GIF's load faster because they dont have to be decompressed.

    and GIF's are really crappy looking because it only uses 256 colors.

    JPG's almost always keep the colors looking good, but the anti-aliasing(keeping it looking smooth) is bad if the image is of lower quality.....

    ok, sure, but parksie, i need your email ad
    Oops...sorry. Guess that is kind of important . Thanks for the code anyway. I see that it uses the Intel JPEG library - I've used that in C++, but never tried to from VB. Could be useful.

    Thumbs up kedaman, please send me a copy

    I think I already got it from one of your posts here, but I misplaced it. Pretty cool, varying the compression (if it's the same code). In fact, I found this post trying to track the other post down.

    Gif's are compressed, they use LZW compression.
