◆ beginTransaction()

void org.mozilla.gecko.gfx.ComposedTileLayer.beginTransaction ( )

inline

Call this before modifying the layer.

Note that, for TileLayers, "modifying the layer" includes altering the underlying CairoImage in any way. Thus you must call this function before modifying the byte buffer associated with this layer.

This function may block, so you should never call this on the main UI thread.
