Subject: Acquiring coordinators for a section of an image

I have a large image loaded into a TImageScrollBox. I then click on an area and it automatically zooms in. I have tried creating a function which will crop the area currently viewable without requiring the user to select the area manually.

The sample crop function requires the coordinates of the area to be cropped; I can get the upper left hand coordinates from the ScrollBars Positions but I can not figure out a way to get the lower right hand coordinates.

I am using Delphi 4 with Envision 1.1 and any help would be appreciated.


Thank-you,

Jason
