Rasterize PDF re-creates the document using images of the pages instead
of vector commands. It functions the same as exporting a PDF to images
and then re-importing the images into a new PDF. After rasterizing the
new document will be opened.

DPI & Compression
DPI Resolution - Resolution
in DPI used to render the page, 72 is the PDF native resolution.
Compression - Sets the
image format. Only images compatible with the PDF format can be chosen.
- JPEG - lossy compression that will reduce image quality and size
- JPEG2000 - less lossy compression that will reduce size and some
- Flate - Lossless compression does not reduce quality but may not
always reduce file size
- JBIG2 B&W - Lossless compression that can only support black
and white color space. Color images will be converted to black and
white. Best for scanned documents with no images
JPEG Quality - This is the quality
of JPEG compression. It varies from 0 (very high compression, very low
quality), to 10 (low compression, very high quality) based on the quality
parameter. Some guidelines for the quality value: 8 high quality, 5 medium
quality, 2 low quality.
