ctglyphinfo.h学习

admin 1月 30, 2021 0

我们从 Glyph Info Types Glyph Info Values Glyph Info Creation Glyph Info Access四个方面来学习。该类的函数具体效果不明，以后研究。

1.Glyph Info Types

1 2	CFTypeID CTGlyphInfoGetTypeID( void ) CT_AVAILABLE(10_5, 3_2); 获取ID

2.Glyph Info Values

typedef CF_ENUM(uint16_t, CTCharacterCollection) {
    kCTCharacterCollectionIdentityMapping CT_ENUM_AVAILABLE(10_8, 6_0) = 0,
 kCTCharacterCollectionAdobeCNS1       CT_ENUM_AVAILABLE(10_8, 6_0) = 1,
 kCTCharacterCollectionAdobeGB1        CT_ENUM_AVAILABLE(10_8, 6_0) = 2,
 kCTCharacterCollectionAdobeJapan1     CT_ENUM_AVAILABLE(10_8, 6_0) = 3,
 kCTCharacterCollectionAdobeJapan2     CT_ENUM_AVAILABLE(10_8, 6_0) = 4,
 kCTCharacterCollectionAdobeKorea1     CT_ENUM_AVAILABLE(10_8, 6_0) = 5,
  kCTIdentityMappingCharacterCollection CT_ENUM_DEPRECATED(10_5, 10_11, 3_2, 9_0) = kCTCharacterCollectionIdentityMapping,
    kCTAdobeCNS1CharacterCollection CT_ENUM_DEPRECATED(10_5, 10_11, 3_2, 9_0) = kCTCharacterCollectionAdobeCNS1,
    kCTAdobeGB1CharacterCollection CT_ENUM_DEPRECATED(10_5, 10_11, 3_2, 9_0) = kCTCharacterCollectionAdobeGB1,
  kCTAdobeJapan1CharacterCollection CT_ENUM_DEPRECATED(10_5, 10_11, 3_2, 9_0) = kCTCharacterCollectionAdobeJapan1,
    kCTAdobeJapan2CharacterCollection CT_ENUM_DEPRECATED(10_5, 10_11, 3_2, 9_0) = kCTCharacterCollectionAdobeJapan2,
    kCTAdobeKorea1CharacterCollection CT_ENUM_DEPRECATED(10_5, 10_11, 3_2, 9_0) = kCTCharacterCollectionAdobeKorea1
};

上面不知道干嘛用的

3.Glyph Info Creation

CTGlyphInfoRef CTGlyphInfoCreateWithGlyphName(
 CFStringRef glyphName,
  CTFontRef font,
 CFStringRef baseString ) CT_AVAILABLE(10_5, 3_2);

CTGlyphInfoRef CTGlyphInfoCreateWithGlyph(
 CGGlyph glyph,
  CTFontRef font,
 CFStringRef baseString ) CT_AVAILABLE(10_5, 3_2);

CTGlyphInfoRef CTGlyphInfoCreateWithCharacterIdentifier(
   CGFontIndex cid,
    CTCharacterCollection collection,
   CFStringRef baseString ) CT_AVAILABLE(10_5, 3_2);

4.Glyph Info Access

1 2	CFStringRef __nullable CTGlyphInfoGetGlyphName( CTGlyphInfoRef glyphInfo ) CT_AVAILABLE(10_5, 3_2);

1 2	CGFontIndex CTGlyphInfoGetCharacterIdentifier( CTGlyphInfoRef glyphInfo ) CT_AVAILABLE(10_5, 3_2);

1 2	CTCharacterCollection CTGlyphInfoGetCharacterCollection( CTGlyphInfoRef glyphInfo ) CT_AVAILABLE(10_5, 3_2);
