Cropping Image to Make Thumbnail Using Rectangle Object
Posted on 2009-05-19
I am writing a program to manage an online image gallery and would like to include thumbnail creation.
I would like the user to be able to select a region of a JPG by dragging a 100 x 100 pixel rectangle object around within a picturebox.
I would then like to be able to take the area of the image that lies within the bounds of the rectangle and save it as its own JPG.
I've not done any work with image manipulation in VB before, and I am just looking for input or advice on making this happen. It seems like it should be easy enough, but I don't know where to start.
