Example
using Leadtools;
using Leadtools.Codecs;
using Leadtools.ImageProcessing;
public void RasterRegionTransformExample()
{
string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp");
string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1_TransformRegion.bmp");
using (RasterCodecs codecs = new RasterCodecs())
{
// Load the source image
using (RasterImage image = codecs.Load(srcFileName, 0, CodecsLoadByteOrder.BgrOrGray, 1, 1))
{
// Add a large elliptical region
image.AddEllipseToRegion(null, new LeadRect(0, 0, image.ImageWidth, image.ImageHeight), RasterRegionCombineMode.Set);
// Fill the image with yellow
FillCommand cmd = new FillCommand(RasterColor.FromKnownColor(RasterKnownColor.Yellow));

// Get the region
using (RasterRegion region = image.GetRegion(null))
{
// Transform this region by making it twice as small
LeadRect bounds = region.GetBounds();

xform.YScalarNumerator = 1;

xform.XOffset = bounds.Width / 2;
xform.YOffset = bounds.Height / 2;
region.Transform(xform);
// Re-set this region into the image
image.SetRegion(null, region, RasterRegionCombineMode.Set);
}
// Now fill with red and save
cmd = new FillCommand(RasterColor.FromKnownColor(RasterKnownColor.Red));
cmd.Run(image);
codecs.Save(image, destFileName, RasterImageFormat.Bmp, 24);
