cairoPopGroupToSource: cairoPopGroupToSource

Description

Terminates the redirection begun by a call to cairoPushGroup or cairoPushGroupWithContent and installs the resulting pattern as the source pattern in the given cairo context.

Usage

cairoPopGroupToSource(cr)

Arguments

cr

[Cairo] a cairo context

Details

group <- cr$popGroup()
cr$setSource(group)
