Hi there,
I'm looking for a solution to draw a one pixel sized point to a graphics
control. E.g. DrawLine(10,10, 11,11) draws 2 pixels, DrawLine(10,10,
10,10) has no effect.
How to do?
Thanks
Pat

Hi,
Possibly not the best solution, but you can use GDI's SetPixel method
through P/Invoke.

pixel method, but thats not fast enough for such a large
surface. So...

Hi,
I have an Image that is drawn with Graphics.DrawImage(..). What I want
to do is drawing it with a given transparency, e.g. at an alpha of only
180 instead of 255.
How am I doing that?!?!?
Regards,

Now I'm wondering if that is the approach I should be taking.
All I want to do is display the DIB or draw it into a Bitmap.
