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.
