Example

This example will warp combines two images.

Remarks

You can warp the entire source image, or a portion of the source image. To warp a portion of the source image, set SourceRectangle accordingly. To warp the entire source image, set the following:


CombineWarp.Command.SourceRectangle = new Rectangle(0, 0, RasterImage.Width, RasterImage.Height);

The warp area in the destination image is specified in SetDestinationPoints. The polygon specified in SetDestinationPoints must:

  • Be concave
  • Fit entirely on the destination bitmap

If either of these conditions is false, this class will throw an exception.

The ordering of the points in SetDestinationPoints can affect the resulting warp. For example, if the source image is the following:

then ordering the points in SetDestinationPoints as shown below results in the following warp:

while ordering the points in SetDestinationPoints as shown below, results in the following warp:

The CombineWarpCommand works by combining the image in the DestinationImage property with the image passed to the RasterCommand.Run method. The DestinationImage will then hold the result of the combine operation..

This command does not support signed data images.
