Generic Function

Package: common-graphics

Arguments: stream

Returns the paint operation in force on stream. A paint-operation specifies how new drawing on a stream will blend with the color already on the screen. The predefined paint-operations are:

po-fill, po-erase, po-paint, po-xor, po-replace, and po-invert.

Note: incompatible change in release 6.0: in releases prior to 6.0, when a frame-with-single-child instance was passed to this operator, the operator was actually applied to the child (the result of applying frame-child to the frame-with-single-child instance). In release 6.0, this redirection no longer occurs. If you intend this operator to apply to the frame-child, pass that to this operator rather than the parent. This is a non-backward-compatible-change. See the release notes for more information.
