Image Scaling

The StretchImage method also draws one bitmap on top of another, but instead of allowing a rectangle of the source bitmap to be selected for the draw operation, the entire source rectangle is stretched or shrunk to fit a destination rectangle.

 Bitmap snowflake = Resources.GetBitmap(Resources.BitmapResources.MFsnowflake); myBitmap.StretchImage(     10, 10,                                // destination x, y     snowflake,                             // source bitmap     200, 100,                              // width and height of destination     0xff);                                 // opacity myBitmap.Flush(); 

Irrespective of the size of the original, the snowflake will be drawn in a rectangle 200 pixels wide and 100 pixels high (Figure 7-9). The snowflake image doubled in width during the draw process.
