A GlyphVector object is a collection of glyphs containing geometric information for the placement of each glyph in a transformed coordinate space which corresponds to the device on which the GlyphVector is ultimately displayed.

The GlyphVector does not attempt any interpretation of the sequence of glyphs it contains. Relationships between adjacent glyphs in sequence are solely used to determine the placement of the glyphs in the visual coordinate space.

Instances of GlyphVector are created by a Font.

In a text processing application that can cache intermediate representations of text, creation and subsequent caching of a GlyphVector for use during rendering is the fastest method to present the visual representation of characters to a user.

A GlyphVector is associated with exactly one Font, and can provide data useful only in relation to this Font. In addition, metrics obtained from a GlyphVector are not generally geometrically scalable since the pixelization and spacing are dependent on grid-fitting algorithms within a Font. To facilitate accurate measurement of a GlyphVector and its component glyphs, you must specify a scaling transform, anti-alias mode, and fractional metrics mode when creating the GlyphVector. These characteristics can be derived from the destination device.

For each glyph in the GlyphVector, you can obtain:

Altering the data used to create the GlyphVector does not alter the state of the GlyphVector.

Methods are provided to adjust the positions of the glyphs within the GlyphVector. These methods are most appropriate for applications that are performing justification operations for the presentation of the glyphs.

Methods are provided to transform individual glyphs within the GlyphVector. These methods are primarily useful for special effects.

Methods are provided to return both the visual, logical, and pixel bounds of the entire GlyphVector or of individual glyphs within the GlyphVector.

Methods are provided to return a Shape for the GlyphVector, and for individual glyphs within the GlyphVector.

getGlyphCharIndexback to summary
public int getGlyphCharIndex(int glyphIndex)

Returns the character index of the specified glyph. The character index is the index of the first logical character represented by the glyph. The default implementation assumes a one-to-one, left-to-right mapping of glyphs to characters.

Parameters

public int[] getGlyphCharIndices(int beginGlyphIndex, int numEntries, int[] codeReturn)

Returns the character indices of the specified glyphs. The character index is the index of the first logical character represented by the glyph. Indices are returned in glyph order. The default implementation invokes getGlyphCharIndex for each glyph, and subclassers will probably want to override this implementation for performance reasons.

Returns:int[]

an array of character indices, one per glyph.

public abstract float[] getGlyphPositions(int beginGlyphIndex, int numEntries, float[] positionReturn)

Returns an array of glyph positions for the specified glyphs. This method is used for convenience and performance when processing glyph positions. If no array is passed in, a new array is created.

Odd numbered array entries beginning with position one are the Y coordinates of the glyph numbered beginGlyphIndex + (position-1)/2. If beginGlyphIndex equals the number of glyphs in this GlyphVector, this method gets the position after the last glyph and this position is used to define the advance of the entire GlyphVector.

the number of glyphs to retrieve

positionReturn:float[]

the array that receives the glyph positions and is then returned.
