Perspective Image Distortion

Question

The application I am working on currently requires functionality for Perspective Image Distortion. Basically what I want to do is to allow users to load an image into the ap

This seems to be exactly what you (and I) were looking for: http://www.codeproject.com/KB/graphics/YLScsFreeTransform.aspx

It will take an image and distort it using 4 X/Y coordinates you provide.

Fast, free, simple code. Tested and it works beautifully. Simply download the code from the link, then use FreeTransform.cs like this:

using (System.Drawing.Bitmap sourceImg = new System.Drawing.Bitmap(@"c:\image.jpg")) 
{ 
    YLScsDrawing.Imaging.Filters.FreeTransform filter = new YLScsDrawing.Imaging.Filters.FreeTransform(); 
    filter.Bitmap = sourceImg;
    // assign FourCorners (the four X/Y coords) of the new perspective shape
    filter.FourCorners = new System.Drawing.PointF[] { new System.Drawing.PointF(0, 0), new System.Drawing.PointF(300, 50), new System.Drawing.PointF(300, 411), new System.Drawing.PointF(0, 461)}; 
    filter.IsBilinearInterpolation = true; // optional for higher quality
    using (System.Drawing.Bitmap perspectiveImg = filter.Bitmap) 
    {
        // perspectiveImg contains your completed image. save the image or do whatever.
    } 
}
