gtk.snapshot
Module for [Snapshot] class
Types 3
classSnapshot : gdk.snapshot.Snapshot
[gtk.snapshot.Snapshot] assists in creating [gsk.render_node.RenderNode]s for widgets.
It functions in a similar way to a cairo context, and maintains a stack of render nodes and their associated transformations.
The node at the top of the stack is the one that gtk_snapshot_append_…() functions operate on. Use the gtk_snapshot_push_…() functions and [gtk.snapshot.Snapshot.pop] to change the current node.
The typical way to obtain a [gtk.snapshot.Snapshot] object is as an argument to the vfunc@Gtk.Widget.snapshot vfunc. If you need to create your own [gtk.snapshot.Snapshot], use [gtk.snapshot.Snapshot.new_].

[gsk.glshader_node.GLShaderNode].void pushMask(gsk.types.MaskMode maskMode)Until the first call to [gtk.snapshot.Snapshot.pop], the mask image for the mask operation will be recorded.void
