    image editing

    Hello people,

    I haven't found anything on my search quest so far, so this is my next stop

    I want my application to create a thumbnail picture from a source image. We'll stick to the 3 formats bmp, jpg and gif. You need to have the option to maintain aspect ratio, and add a special effect like a shadow or something. The format of the loaded picture can also differ from the destination thumbnail.

    My experience with this is nihil. Is this possible in VB? Can anyone help me to get started? I don't need any full working code (of course, it WOULD be handy if you could provide it ) and it's not my intention to make a graphics editor either. I just want to make some kind of custom-made thumbnail generator.

    Thanks in advance for any feedback!

    For the strech thing. Can you use a image box??? If not use BitBlt. Do a search on it on this forum.

    Over to the fileformats. BMP should be fine, but I think that JPG is a protectet file format (or was that gif), so I'm not sure if you can save it as JPG...anyone else???

    The gif compression algorithm is patented.

    Thats because MS pays the people who own the patent . Otherwise, I beileve by the DMCA, it would be illegal to decompress a gif image using their algorithm
