GI.Pango.Objects.EngineShape

Contents

Description

The tEngineShape class is implemented by engines that customize the rendering-system dependent part of the Pango pipeline for a particular script or language. A tEngineShape implementation is then specific to both a particular rendering system or group of rendering systems and to a particular script. For instance, there is one tEngineShape implementation to handle shaping Arabic for Fontconfig-based backends.
