in DB?

if not, just use some image editing program like photoshop or paint shop pro (i think that last one's free)

if you mean in DB, you'll have to store the color value of each pixel in an array, and then you'll have to calculate the colors of the pixels for the resized version
then you create a new bitmap and you draw every pixel in it and save it

Takes file "bitmap.bmp" and converts it to a 800x600 bitmap.
You'd have to save it from Bitmap #2 to disk using your favorite method.

Create Bitmap 2,800,600
Load Bitmap "bitmap.bmp",1
Copy Bitmap 1,0,0,Bitmap Width(1),Bitmap Height(1),2,0,0,800,600


The more you see, the more you know.
