Method Detail

close

public void close()

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class Managed

beginLine

public void beginLine()

Description copied from interface: RunHandler

Called when beginning a line.

Specified by:

beginLine in interface RunHandler

runInfo

public void runInfo(RunInfo info)

Description copied from interface: RunHandler

Called once for each run in a line. Can compute baselines and offsets.

Specified by:

runInfo in interface RunHandler

commitRunInfo

public void commitRunInfo()

Description copied from interface: RunHandler

Called after all RunHandler.runInfo(io.github.humbleui.skija.shaper.RunInfo) calls for a line.

Specified by:

commitRunInfo in interface RunHandler

runOffset

public io.github.humbleui.types.Point runOffset(RunInfo info)

Description copied from interface: RunHandler

Called for each run in a line after RunHandler.commitRunInfo().

Specified by:

runOffset in interface RunHandler

Returns:

an offset to add to every position

commitRun

public void commitRun(RunInfo info,
                      short[] glyphs,
