Hi There,

I've been trying to use the Graphics instance generated by the PrintDocument to render Alpha Blending graphical objects (i/e rectangle filled with Brush=100,255,0,0) - but without any luck, they all appear.... defected in a way, can't really point the finger on whats going on there... (check out this capture: http://i36.tinypic.com/a0jdyh.jpg).

Anyhow, what i know is:

- This is true to both 300/600 dpis.
- This true even when printing to PDF/OneNote (not really printer/driver problem)
- This happens even when the PrinterResolutionKind set to High.
- When PrintPreview'ing this doesn't happen.
- When first rendering to bitmap and then to the Graphics, this doesn't happen (but i cant use it cuz out of memory on large images)
-

Any ideas??


Thanks
