How to resize bmp image on C?

Question

For jpeg,gif,png I use libgd. ( not ImageMagick - it's not possible ). May I resize bmp image using simple method/library ?

Answer 1

Most of the libraries that deal with image resizing represent the image as a bitmap (i.e. an uncompressed array of pixels) internally. So it wouldn't be very hard to read in a bitmap image from a file and put it in memory.
