Vue de l’ensemble
‘TrueTypeReader’ est une classe dans Aspose.PDF FOSS pour Java.
Il rédige les fichiers de texte TrueType/OpenTYpe (en format SFNT).
Cette classe fournit 12 méthodes pour travailler avec des objets TrueTypeReader dans les programmes Java. Les méthodologies disponibles comprennent: ‘TrueTYpe Reader’, ‘getAdvanceWidth’, getCmapEntries', ‘getFontName’, ' getGlyphId', ’getGryphNamen', ‚getNumGliphs, ’netUnicodeForGlithIde’, ‘‘getUniceForLithInPremierUniciode’,‘‘getUnitsPerEm’,‘hasnicodCmap’. Tous les membres publics sont accessibles à toute application Java après l’installation de l’Aspose.PDF FOSS pour le package Java . Propriétés : cmcimètre Ents, n°Nome, N°Glephnume, PerunitsEm.
Propriétés
| Name | Type | Access | Description |
|---|---|---|---|
unitsPerEm | int | Read | Returns the font’s unitsPerEm value from the head table. |
numGlyphs | int | Read | Returns the number of glyphs in the font. |
fontName | String | Read | Returns the font name from the name table (if available). |
cmapEntries | java.util.Map<Integer, Integer> | Read | Returns an unmodifiable view of the Unicode-to-glyph cmap as a map. |
méthodes
| Signature | Description |
|---|---|
TrueTypeReader(data: byte[]) | Creates a TrueTypeReader from raw font data. |
getUnitsPerEm() → int | Returns the font’s unitsPerEm value from the head table. |
getNumGlyphs() → int | Returns the number of glyphs in the font. |
getGlyphId(charCode: int) → int | Maps a character code to a glyph ID using the cmap table. |
getUnicodeForGlyphId(glyphId: int) → int | Returns the first Unicode code point mapped to the given glyph ID. |
getUnicodeForGlyphIdPreferUnicode(glyphId: int) → int | Returns the Unicode code point for the given glyph ID using ONLY the |
| true-Unicode cmap subtables (see {@link #unicodeReverseCmap}). | |
hasUnicodeCmap() → boolean | Returns true if the font ships at least one true-Unicode cmap subtable |
| (platform 3 encoding 1/10, or platform 0). | |
getGlyphName(glyphId: int) → String | Returns the PostScript name for the glyph from the {@code /post} table, |
| or {@code null} if the post table was missing, used a format we don’t | |
| parse, or the glyph id is out of range. | |
getAdvanceWidth(glyphId: int) → int | Returns the advance width for the given glyph ID, in font units. |
getFontName() → String | Returns the font name from the name table (if available). |
getCmapEntries() → java.util.Map<Integer, Integer> | Returns an unmodifiable view of the Unicode-to-glyph cmap as a map. |
getGlyphPath(gid: int) → java.awt.geom.GeneralPath | Returns the outline of a glyph as a {@link java.awt.geom.GeneralPath} in |
| em-normalised coordinates (font units divided by {@code unitsPerEm}), with | |
| the TrueType Y-up orientation preserved. |
