System Options That Affect PDF Output
Before you create PDF output, you can use SAS system options to set document security
restrictions. The document security restrictions specify what can be done to the
document, as well as the security method, the printing resolution, and the encryption
level.
The following table lists the system options that can be used to set the PDF document

Creating PNG (Portable Network Graphics) Files
Using Universal Printing
Portable Network Graphics in SAS
Portable Network Graphics (PNG) is an image format that was designed to replace GIF
and TIFF image formats that are viewed on the World Wide Web. PNG images that are
created with the SAS Universal Printer or a SAS/GRAPH device driver use the PNG
Reference Library, also known as Libpng. PNG is the default format for graphics output
for the ODS HTML destination and for SAS/GRAPH.
