What does TIECanvas.Brush.BackColor and TIECanvas.Brush.BackTransparency do? How do these values affect TIECanvas drawing?

I can not find any explanation or any info about this.

Hi Bill

Both BackColor and BackTransparency are used to set the backColor property of the GDI+ HatchBrush:

BackColor is the color, and BackTransparency is the alpha value.

It would have been a lot easier to understand if BackColor was called HatchColor and if BackTransparency was called HatchTransparency. I'd recommend you change his sometime. Hatch is easier to understand because "Hatch" is easier than "Back" which actually has no meaning.

Hi Bill

Perhaps, but I think we are stuck with it now
