Type String Object SnapshotObject Library display.* Revision 2017.3122 Keywords canvas, canvasMode See also display.newSnapshot() snapshot.canvas
The canvas mode controls what happens to the children of the snapshot's canvas.
This mode comes into play when the canvas is invalidated (i.e. calling
snapshot:invalidate("canvas")). On the next render pass, the children will be removed from the canvas. The mode controls where those children go:
"append"— This is the default. The children will be appended to the snapshot's group on the next render pass.
"discard"— The children will be discarded on the next render pass.
