In the Demo: \Demos\ImageEditing\FillTool\, at design-time, the BackgroundStyle = iebsChessboard (and the chessboard is visible at design-time).

1. But when I run the program (without loading an image), the chessboard is no more visible. Why? How can I show the chessboard set at design-time at run-time too?

2. Then I load an image and flood-fill an area with alpha-transparency. Why is the chessboard background not shining through the transparent area? How can I achieve this?

Hi

1. By default ImageEn initializes with a blank image the size of the control. You should call ImageEnView1.Blank();

2. Is ImageEnView1.EnableAlphaChannel enabled? Does the ImageEnView1.IEBitmap have an alphachannel?
