Q:
I encountered a PDF that is taking a very long time to load. The
delay seems to be mainly coming from the "text" (appears to be a bunch
of dots). Acrobat and the PDFView sample program both encounter a
slow-down when rendering the text, but PDFView seems to be slower. Is
there a way to optimize the rendering of this type of PDF?

A:
The slowdown stems from text that is represented very inefficiently
(using thousands of line segments and rectangles to represent pixels
of each character. Unfortunately we can do a little to speed up the
build-in rasterizer (where all rendering is done in software), however
if you switch to GDI+ rasterizer (in PDFView sample project select
'Menu > Options > Built-In Rasterizer') you will notice significant
performance improvement (similar or better than Acrobat).
