Q:
Is PDFNet supporting the ability to rasterize an entire page from a
image+text pdf file into a gdi+ bitmap object?
A:
You can use pdftron.PDF::PDFDraw.GetBitmap() method to obtain GDI+
bitmap for a given PDF page. As a starting point, you may want to take
a look at PDFDraw sample project: http://www.pdftron.com/net/samplecode.html#PDFDraw
