Re: Printing to PDF -- poor bitmap quality

I tried each of the 9 different possible modes, but no luck. And
again, everything looks great when my device context is the screen, an
actual printer, or even a TIFF. This tells me that it has to be a
problem with Acrobat. Unfortunately, they've been no help.

The bitmap that I'm trying to render is actually the result of some
code that Ken Tucker posted for rendering the contents of a
RichTextBox. It works wonderfully. Unfortunately, since it appears
that printing to PDF doesn't work well with bitmaps, I'm going to have
to find a way to parse RTF markup and render it using DrawString,
Fonts, etc. Yippee...

Try setting the InterpolationMode on the Graphics object to one of the

slower and seems to deliver a worse result for all it's supposed advantages.

I'm rendering text (DrawString) and images (DrawImage). The output
looks great on screen and looks great when printing to a printer (both
Laser and Inkjet).

When printing to Adobe PDF (which is what my users will mostly be
doing), the sections rendered using DrawString look great, but the
images rendered using DrawImage look blocky and pixellated. I've
tried modifying the Adobe Settings hoping that it would increase the
image quality, but no luck. I've tried several ideas found in Acrobat
Support, but no luck.
