Re: pictureBox fusion

I have 2 pictures. One is made of only 3 circles with the same center and different rays, with 360 small around around
the greatest circle, to represent 360 degrees.

The 2nd one is a chart made of polygons with many many points (around 100,00), redrawn many times a minute

I wish to "join" both pictures in the same pictureBox without having to redraw the first one every time , is this
something possible ? If so, how ?

What colour is the first picture (the one which has to be overlaid on-top of the polygons?) If red, green, blue, black
or white (or swapping to the inverse of the underlying colour) then you can do this with a simple BitBlt() raster
operation, otherwise you're looking at either two blits or re-rasterisation every frame, both of which are more costly.
Hope this helps,

Mike
