Cutting and saving piece of JPG-file...
Posted on 2002-04-01
Hi dear experts!
I have a JPEG-image stored on disk (MyPic.jpg). Its size is 400x300 pixels, and the color-depth is 24 bit.
Now I would like to cut out the region (100,100,199,199) and save it both as a BMP (MyBmp.bmp) and a JPG (MyJPG.JPG). Now, the thing is that I want the two new pictures to be only 50x50 pixels in size. How do I do this?
Actually, I've managed to do it, but when using CopyRect the colors get terribly degraded and I don't know why. Could someone please give me full source for this problem, including creating and destroying of all components needed in the transformation?
