Yes it is possible using the ImageLib library.
You should create a bitmap object and a drawer object that will draw over this bitmap.
Now draw the form's image on the bitmap using drawer.DrawImage1. It allows you to choose which part of the source image will be drawn.
Save the bitmap image using ImageLibEx (and bitmap.Value).
Only the bitmap object supports SetPixel.
B4PObject is a keyword that is sometimes required by other libraries.
For example:
[FONT=Times New Roman][COLOR=#010101]drawer.New2 (ImageList1.Item(0), B4PObject(5))[/COLOR][/FONT]
