Hi,
I looked again and I see my advice was wrong, the protected method I
looked at is final, and the other one is private.
The next thing that you could try is to create your own
SetGraphicsStateParameters class, and call addOperator(new
SetGraphicsStateParameters()); in your own drawer.
The new class should be like the old class but with this modification
PDExtendedGraphicsState gs =
context.getResources().getExtGState(graphicsName); // existing line
gs.setNonStrokingAlphaConstant(1f);
gs.setStrokingAlphaConstant(1f);

Thanks. Do you mind offering a pointer on how to perform this? For
example, *getNonStrokingPaint*() and *getStrokingPaint*() return Paint
objects. Should I be forcing *setAlphaConstant*() and
*setNonStrokeAlphaConstant*() like this code example?

As a quick test, I hard-coded them to always set/return "1" in
*PDGraphicsState * and it appears to fix the rasterization of the
second page, but I'd like to be able to make this toggleable.
Here's my current code:

which is largely based on a conversation here:
