• You can add a printer’s mark that is not visible in Universal Printing output by using
the COLOPHON= system option.
• SVG documents can be magnified by setting the SVGMAGNIFYBUTTON system
option. SAS embeds a magnify tool in the document when the SVG document is
created.
See “Creating TIFF Images Using Universal Printing” on page 341.
Font Slanting and Emboldening Support
In the second maintenance release of SAS 9.4, if you specify italic or bold styles on a
universal printer font that does not have an italic or bold style, the font will now be
displayed as slanted or bold by default. See “Slanting and Emboldening Fonts” on page
293.
TrueType Fonts
SAS 9.4 supports the following new fonts and font replacements:
• Helvetica LT Pro and Symbola TrueType fonts on page xii are supported beginning
with the fourth maintenance release of SAS 9.4.
• “Avenir Next TrueType Fonts” on page xiii are supported beginning with the third
maintenance release of SAS 9.4.
• The Monotype Sans WT (J,K,SC,TC) fonts are replaced by the new Arial Unicode
MS font.
• The Thorndale Duospace WT (J,K,SC,TC) fonts are replaced by the new Times New
Roman Uni font.
• Sim Hei, SimSun, and NSimSun are replaced by CSongGB18030C-Light,
CSongGB18030C-LightHWL, MYingHei_18030_C-Medium, and
MYingHei_18030_C-MediumHWL.
See “TrueType Fonts Supplied by SAS” on page 286.
Helvetica and Symbola TrueType Fonts
The following Helvetica LT Pro TrueType fonts and the Symbola font are new in the
fourth maintenance release of SAS 9.4:
Font Name
Helvetica LT Pro Regular
Helvetica LT Pro Bold
Helvetica LT Pro Italic
Helvetica LT Pro Bold Italic
Helvetica LT Pro Light
