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

security restrictions:

System Option Description

PDFACCESS Specifies whether the PDF document can be edited.

PDFASSEMBLY Specifies whether PDF documents can be assembled.

PDFCOMMENT Specifies whether PDF document comments can be modified.

PDFCONTENT Specifies whether the contents of a PDF document can be

changed.

PDFCOPY Specifies whether text and graphics from a PDF document can

be copied.

PDFFILLIN Specifies whether PDF forms can be filled in.

PDFPAGELAYOUT Specifies the page layout for PDF documents.

PDFPAGEVIEW Specifies the page viewing mode for PDF documents.

PDFPASSWORD Specifies the password to use to open a PDF document and the

password used by a PDF document owner.

PDFPRINT Specifies the resolution to print PDF documents.

PDFSECURITY Specifies the level of encryption for PDF documents.

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.

Creating PNG (Portable Network Graphics) Files Using Universal Printing 311

For a description of the PNG printer, you can either view the printer in the SAS registry

or submit the following QDEVICE procedure and view the output in the SAS log:

proc qdevice;

printer png;

run;

The PNG Universal Printers

SAS provides three PNG Universal Printers.

Table 15.18 PNG Universal Printers Provided by SAS

Printer Name Description

PNG produces PNG images at 96 dpi

PNGt produces PNG images at 96 dpi with a transparent background

PNG300 produces PNG images at 300 dpi

PNG printers do not support multiple page documents. If a procedure creates multiple

pages or if more than one procedure is used in the code for ODS PRINTER output, only

the first page is viewable.

Creating a PNG Image

You can create a PNG image using the ODS PRINTER statements. You specify the PNG

Universal Printer as the value of the PRINTERPATH= system option or as the value of

the PRINTER= option in the ODS PRINTER statement.

Here is sample code to create a PNG image:

ods html close;

ods printer printer=png;

...more SAS code...

ods printer close;

ods html;

SAS creates the file sasprt.png in the current directory.

In SAS/GRAPH, the PNG device is a shortcut to the PNG Universal Printer. For

information about creating PNG images using SAS/GRAPH devices, see SAS/GRAPH:

Reference.

Example of Creating a PNG File Using the ODS PRINTER Statement

To create a PNG image in SAS using one of the PNG Universal Printers, specify the

PNG printer in the PRINTERPATH= system option and the ODS PRINTER statement as

shown in the following example:

312 Chapter 15 • Printing with SAS

options printerpath=png nodate;

ods html close;

ods printer;

proc sgplot data=sashelp.stocks

(where=(date >= "01jan2000"d and stock = "IBM"));

title "Stock Trend";

series x=date y=close;

series x=date y=low;

series x=date y=high;

run;

ods printer close;

ods html;

The following output is the PNG graphic displayed in Windows Picture and Fax Viewer:
