Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void RasterRegionExample() 
{ 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
   string destFileName1 = Path.Combine(LEAD_VARS.ImagesDir, "Image1_WithRegion1.bmp"); 
   string destFileName2 = Path.Combine(LEAD_VARS.ImagesDir, "Image1_WithRegion2.bmp"); 
 
   using (RasterCodecs codecs = new RasterCodecs()) 
   {

            Console.WriteLine("IsEmpty: {0}\nBounds: {1}", region.IsEmpty, region.GetBounds());

            image.SetRegion(null, region, RasterRegionCombineMode.Set);

            // Set it into the image and fill again with red, notice 
            // that this will fill the whole image since 
            // the region is now empty
