I've a problem I'm not able to solve: I need to draw a line on a bitmapviewer and then to erase the line restoring background image. I cannot reload image because is big and there are other drawing addedd.
The problem is to use a sort of XOR drawing.
Is that possible?
thank to all

Hello, Unfortunately, Graphics Mill for .NET does not support XOR drawing. I wonder, what feature are you trying to implement? Could you provide more details, maybe I will be able to suggest you another ways to solve this issue? You can submit case also if it is more convenient for you.

I simply need to draw a cross line on a bitmapviewer when I click the image with the mouse: if the user click again on the image I need to delete the previous cross line (showing the original background) and redraw the line in the new poisiton.
Thank to all.

Hello, I think that it will be easier to implement this feature via Rubberband. If I understand you correctly, your cross-marks are not part of the image, so there are no need to actually draw them on it. I suggest you to implement custom rubberband object, which will store coordinates of the cross-mark and it will draw it on the specified place. You can find more detailed information about creating custom rubberbands in this article: http://www.aurigma.com/d...berbandsWindowsForms.htmEdited by user Wednesday, October 29, 2008 3:12:02 AM(UTC)
