Hi,
if SelectionGridSize = 5 then It will display a 5 * 5 Grids. It is
very nice. But if I just need a 5 * 3 Grids, How Could I do. Thanks

Hi,
at the moment it is not possible to specify n*m sizes.
From next minor release (or next beta) there will be two new properties named SelectionGridWidth and SelectionGridHeight, so you will be able to write:

ImageEnView.SelectionGridWidth:=5;
ImageEnView.SelectionGridHeight:=3;

Hi,
Thanks.
I try to draw lines with canvas. but there is a problem. those Lines are offsets beause ImageEnView and real Images have a blank area. How could i get
the coordinate of the blank area.

Hi,
these are the coordinates of the (painted) image bounding box:

left = ImageEnView.OffsetX
top = ImageEnView.OffsetY
width = ImageEnView.ExtentX
height = ImageEnView.ExtentY
