pixmap-handle

Arguments: pixmap

Returns the handle to the device-dependent bitmap for the main (not mask) texture of the argument pixmap, if it has been given one by calling open-pixmap-handle, and otherwise returns nil. This function is useful for determining whether the pixmap currently has such a handle, though the particular handle is not useful for Common Graphics code. This handle corresponds to the main texture stored in the texture property of the pixmap; see mask-handle for the handle corresponding to the mask texture.

pixmap-handle is a property of the pixmap class. See also close-pixmap-handle.
