Determine the height and width; change them as you want. Then copy to a new image with the new dimensions.

There is a lot of information available there. Cropping is maybe the most complicated part, but you can do this in the following way: first, determine new width then calculate the desired new height. Based on that, you can use the $src_x, $src_y, $src_w and $src_h to select the upper left corner and then how much of the image you want, such as "0,0,360,480": start at the far upper left corner then take a section that is 360 wide (full original width) and 480 tall--- that's the hard number to determine: it's in the same ratio as the new image. Algebra: 320/240 = X/360. => X = (360*320)/240 = 480.
