2.1.1.10 FontQuality Enumeration

  • Article

The FontQuality Enumeration specifies how closely the attributes of the logical font match those of the physical font when rendering text.

 typedef  enum
 {
   DEFAULT_QUALITY = 0x00,
   DRAFT_QUALITY = 0x01,
   PROOF_QUALITY = 0x02,
   NONANTIALIASED_QUALITY = 0x03,
   ANTIALIASED_QUALITY = 0x04,
   CLEARTYPE_QUALITY = 0x05
 } FontQuality;

DEFAULT_QUALITY: Specifies that the character quality of the font does not matter, so DRAFT_QUALITY can be used.

DRAFT_QUALITY: Specifies that the character quality of the font is less important than the matching of logical attribuetes. For rasterized fonts, scaling SHOULD be enabled, which means that more font sizes are available.

PROOF_QUALITY: Specifies that the character quality of the font is more important than the matching of logical attributes. For rasterized fonts, scaling SHOULD be disabled, and the font closest in size SHOULD be chosen.

NONANTIALIASED_QUALITY: Specifies that anti-aliasing SHOULD NOT be used when rendering text.<7>

ANTIALIASED_QUALITY: Specifies that anti-aliasing SHOULD be used when rendering text, if the font supports it.<8>

CLEARTYPE_QUALITY: Specifies that ClearType anti-aliasing SHOULD be used when rendering text, if the font supports it.<9>

Fonts that do not support ClearType anti-aliasing include type 1 fonts, PostScript fonts, OpenType fonts without TrueType outlines, rasterized fonts, vector fonts, and device fonts.
