Does LeadTools provide a method to use Bitmap to fill a irregular region?

If you want to fill part of the image with a certain color, you simply need to define a region that covers that part (such as a polygon region) and then call the Fill function appropriate for your programming interface. The will cause filling to be restricted to the pixels within the region area.
If you need help doing that, send us more details about what you're trying to do exactly, including which Programming interface (OCX, .NET classes, DLL API, C++ Classes, etc.) you are using.

If you want to take part of the image (region of interest) and fill it with a certain pattern instead of a solid color, you can do that as follows:

1. Load a secondary image that contains the pattern, or create an empty image and draw the pattern in it. This pattern image should be equal in size or larger than the desired region.

2. Define the desired region in the target image using the Region functions (such as RasterImage.AddRectangleToRegion).

3. Use the CombineFastCommand class or the CombineCommand class to copy the pattern from the pattern image to the region in the target image.

Hi,
this is ok, but here another part of the problem. In some case I need to fill with the same texture an AnnFreeHotSpotObject. I'm able to this in the same way you suggest, but if I apply the PerspectiveCommand to the texture bitmap, it comes stretched and borders filled with the specified color appears, so I try to use the PerspectiveCommandType.Image parameter for the PerspectiveCommand, but also this fails because the texture is filled with the original image. Look at the attached images.

Thanks!
