I looked at the FillTool demo.
These are the lines in the demo that interest me:

  ImageEnView1.FillTool.Tolerance  := updTolerance.Position;
  ImageEnView1.FillTool.SampleSize := updSampleSize.Position;
  ImageEnView1.FillTool.MaxFilter  := chkMaxFilter.Checked;
  ImageEnView1.FillTool.ColorFillValue := btnFillColor.SelectedColor;
  ImageEnView1.MouseInteractGeneral := [ miColorFill ];


I want to imitate the demo programmatically to do the following:
1. Select a region of an image
2. Fill (replace) with a color at a specific pixel in the region similar to using the demo when I click on a pixel in the image.

My reasoning is to do it in batch to many images.

Hi Waheed

Internally the fill tool is just using this method:
