2.1.11 ExtTextOutOptions Enumeration

  • [アーティクル]

The ExtTextOutOptions enumeration specifies parameters that control various aspects of the output of text by EMR_SMALLTEXTOUT (section 2.3.5.37) records and in EmrText objects.

 typedef  enum 
 {
   ETO_OPAQUE = 0x00000002,
   ETO_CLIPPED = 0x00000004,
   ETO_GLYPH_INDEX = 0x00000010,
   ETO_RTLREADING = 0x00000080,
   ETO_NO_RECT = 0x00000100,
   ETO_SMALL_CHARS = 0x00000200,
   ETO_NUMERICSLOCAL = 0x00000400,
   ETO_NUMERICSLATIN = 0x00000800,
   ETO_IGNORELANGUAGE = 0x00001000,
   ETO_PDY = 0x00002000,
   ETO_REVERSE_INDEX_MAP = 0x00010000
 } ExtTextOutOptions;

ETO_OPAQUE: This bit indicates that the current background color SHOULD be used to fill the rectangle.

ETO_CLIPPED: This bit indicates that the text SHOULD be clipped to the rectangle.

ETO_GLYPH_INDEX: This bit indicates that the codes for characters in an output text string are indexes of the character glyphs in a TrueType font. Glyph indexes are font-specific, so to display the correct characters on playback, the font that is used MUST be identical to the font used to generate the indexes.<23>

ETO_RTLREADING: This bit indicates that the text MUST be laid out in right-to-left reading order, instead of the default left-to-right order. This SHOULD be applied only when the font selected into the playback device context is either Hebrew or Arabic.<24>

ETO_NO_RECT: This bit indicates that the record does not specify a bounding rectangle for the text output.

ETO_SMALL_CHARS: This bit indicates that the codes for characters in an output text string are 8 bits, derived from the low bytes of Unicode UTF16-LE character codes, in which the high byte is assumed to be 0.

ETO_NUMERICSLOCAL: This bit indicates that to display numbers, digits appropriate to the locale SHOULD be used.<25>

ETO_NUMERICSLATIN: This bit indicates that to display numbers, European digits SHOULD be used.<26>

ETO_IGNORELANGUAGE: This bit indicates that no special operating system processing for glyph placement is performed on right-to-left strings; that is, all glyph positioning SHOULD be taken care of by drawing and state records in the metafile.<27>

ETO_PDY: This bit indicates that both horizontal and vertical character displacement values SHOULD be provided.<28>

ETO_REVERSE_INDEX_MAP: This bit is reserved and SHOULD NOT be used.<29>
