I have a problem with my picturebox. I draw alot of lines and data in it and everything works fine.

From the beginning the size of the picturebox is 600x600 and it has to be. When I have finished drawin in it, I need to "Cut" the picture down to 600x300, In other words cut the bottom half out. I do this because sometimes it's no data there, and when I save the picture with the SavePicture function, the picture will be half the size if I cut it down to 600x300 instead of 600x600.

Here is the problem: When I change the height of the picture to 300 and then save it, it will still be the same size(600x600) with the same unnecessary space in the picture.



In short : I want to "Cut off" the bottom half of a picture in a picturebox....how do I do this .. ??
