Image zoom (with source)

A small tool that scales pictures by a given size, supporting the scaling of animated GIF graphs.

Main code :

 Public classFormatimage { Public Static stringformatallimage (imageinfo info) {System.Drawing.Image Image=System.Drawing.Image.FromFile (info.

Sizeheigth) {//determine if a picture is a dynamic graph (animated pictures have multiple frames)                    if(Image.
