A cluster of Unicode code points and glyphs.
An object of this class contains a sequence of Unicode code points and a sequence of glyphs.
In the ideal case, each cluster contains exactly one Unicode code point and one glyph, making the relationship between the two unambiguous.
In the general case, the number of Unicode code points can be different from the number of glyphs and the relationship between the Unicode code points of the cluster and the glyphs of the cluster is unknown.
There can be more glyphs than Unicode code points, more Unicode code points than glyphs (e.g., for a ligature), or the same number of glyphs and Unicode code points.
The clusters returned by SignDocDocument.findText() may contain more characters than have been searched for (as clusters cannot be broken up). If a cluster contains multiple instances of the search text, SignDocDocument.findText() will return multiple instances of that cluster.
~SignDocTextCluster | ( | ) |
Destructor.
!SignDocTextCluster | ( | ) |
Finalizer.
SignDocTextCluster | ( | SignDocTextCluster | aSource | ) |
Copy constructor.
[in] | aSource | The object to be copied. |
double getGlyphAdvanceWidth | ( | int | aIndex | ) |
Get the advance width of a glyph.
[in] | aIndex | The 0-based index of the glyph. The order of the glyphs is unspecified. |
Rect getGlyphBoundingBox | ( | int | aIndex | ) |
Get the bounding box of a glyph.
[in] | aIndex | The 0-based index of the glyph. The order of the glyphs is unspecified. |
double getGlyphFontSize | ( | int | aIndex | ) |
Get the font size for a glyph.
[in] | aIndex | The 0-based index of the glyph. The order of the glyphs is unspecified. |
int getGlyphPage | ( | int | aIndex | ) |
Get the page on which a glyph appears.
In extreme (theoretical) cases, the glyphs of a single cluster can appear on different pages, even on pages outside the range of pages passed to SignDocDocument.findText() or SignDocDocument.createTextIterator().
[in] | aIndex | The 0-based index of the glyph. The order of the glyphs is unspecified. |
Point getGlyphReferencePoint | ( | int | aIndex | ) |
Get the reference point of a glyph.
[in] | aIndex | The 0-based index of the glyph. The order of the glyphs is unspecified. |
int getGlyphTextRenderingMode | ( | int | aIndex | ) |
Get the text rendering mode for a glyph.
[in] | aIndex | The 0-based index of the glyph. The order of the glyphs is unspecified. |
int getNumberOfGlyphs | ( | ) |
Get the number of glyphs in this cluster.
The order of the glyphs is unspecified.
int getPage | ( | ) |
Get the page on which the glyphs of this object appear.
The glyphs of a can appear on different pages, even on pages outside the range of pages passed to SignDocDocument.findText() or SignDocDocument.createTextIterator().
int [] getPages | ( | ) |
Get the pages on which the glyphs of this object appear.
The glyphs of a can appear on different pages, even on pages outside the range of pages passed to SignDocDocument.findText() or SignDocDocument.createTextIterator().
string getText | ( | ) |
Get the Unicode code points of the cluster.
int getUnicodeDirection | ( | ) |
Get the direction implied by the Unicode code points.
A lot of characters (such as punctuation characters) do not imply a direction. Unless there is at least one character that defines a direction, 0 will be returned. 0 is also returned if there are conflicting directions.
