Export to pdf; picture quality

I use Visual Studio .NET 2003 but I'm a newbie concerning Crystal Reports.

I created a report based on an ADO.NET Dataset and export it to PDF.
The Report contains a BLOB-Field, to show a picture from the DataSet.

I found out, that the images must have a resolution of 96 dpi, that CR shows them in the correct size. But I definitly need a better resolution (because the images contain text elements).

When I try to store the image in a better resolution and down-scale the image-field in the report, the result of the exported pdf will not be better.

Any solutions for "higher-quality-images" in exported PDFs??

Minutes before your answer, I found the first article by myself.

Anyway, the answer was useful; the points are yours.

The change of the reg-keys made it better but I'm still not satisfied:
I don't see a difference when changing the "Denominator"key.
Or when I set the Nominator to 8, the quality improves, but setting it to 12 makes it worse.
???


Right now I save the Bitmap with 300 dpi in the database.
In my report I set the XScaling and YScaling property of the BLOB-field to 0.32 (=96/300).
And in the registry I use 8 for the Nominator and 1 for the Denominator.


Any hints for optimal/better values??
