As an example, if you use the following figure:
And you use the following figure as the canvas image:
And you call CanvasCommand using the following values:
The following figure results:
In the following figure the rafting image has been combined with the canvas image using the same values, except that the CanvasCommandFlags.TileFit flag is used and so instead of tiling the canvas image has been stretched to fit the dimensions of the rafting image:
Other commands that allow you to combine images include:
For more information on this and other commands that can be used to combine images, Refer to Introduction to Image Processing With LEADTOOLS.
This command supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit and 64-bit color images is available only in the Document/Medical toolkits.
