Hi,

I am using the annotation control TLeadAnn in Delphi 2006 (VCL - version 14.5).

We have a jpeg-image with hotspots (rectangular and freehand).

Now I want to fill the area occupied by of a particular hotspot with a color, and cross-hatch it (fill with a pattern)

I have managed to fill the area with a color, but I can't do any pattern-filling.

Can anyone give me a clue how to do that ?

Thanks in advance,

Fred

What is the nature of the pattern? Is it a bitmap
or is it something that you want to draw? In either case, you can load or draw
the pattern in a secondary bitmap, then combine it with the original bitmap using region processing.

Thanks Qasem, for your response.

Using a secondary bitmap & combining does the trick.
