shapeJustify

See harfbuzz.global.shapeFull for basic details. If shaper_list is not NULL, the specified shapers will be used in the given order, otherwise the default shapers list will be used.

In addition, justify the shaping results such that the shaping results reach the target advance width/height, depending on the buffer direction.

If the advance of the buffer shaped with harfbuzz.global.shapeFull is already known, put that in *advance. Otherwise set *advance to zero.

This API is currently experimental and will probably change in the future.

Parameters

minTargetAdvance float: Minimum advance width/height to aim for.
maxTargetAdvance float: Maximum advance width/height to aim for.
advance float: Input/output advance width/height of the buffer.
varTag harfbuzz.types.Tag: Variation-axis tag used for justification.
varValue float: Variation-axis value used to reach target justification.

Return Value

Type: harfbuzz.types.Bool

false if all shapers failed, true otherwise
