Method Details

lock

public void lock()

unlock

public void unlock()

getGlyph

public @NonNull Glyph getGlyph(int packedID)

Find or create a glyph for the given glyph ID, return the pointer to it.

Requires lock.

Parameters:

packedID - typeface-specified glyph ID

digestFor

public @NonNull Glyph digestFor(int actionType,
 int packedID)

Find or create a glyph for the given glyph ID, return the pointer to it. Get or compute the digest for the given action type, ensure that Glyph.actionFor(int) is set.

Requires lock.

Parameters:

actionType - e.g. Glyph.kDirectMask

packedID - typeface-specified glyph ID

prepareForImage

public boolean prepareForImage(@NonNull Glyph glyph)

Prepare the glyph to draw an image, and return if the image exists.

Requires lock.

prepareForPath

public boolean prepareForPath(Glyph glyph)

Prepare the glyph to draw a path, and return if the path exists.

Requires lock.

getMetrics

public Glyph @NonNull [] getMetrics(int @NonNull [] glyphs,
 int glyphOffset,
 int glyphCount,
 Glyph @NonNull [] results)

Compute metrics for a list of glyphs in bulk. The glyph metrics within the given range will be computed, and the glyph pointers will be stored in the results array and returned.

Excludes lock.

getStrikeDesc

public @NonNull StrikeDesc getStrikeDesc()

getSubpixelRounding

public float getSubpixelRounding()

getSubpixelFieldMask

public int getSubpixelFieldMask()
