GXFinishSendPlane

QuickDraw GX sends the GXFinishSendPlane message to mark the end of processing of a plane or "color pass" for raster devices. You can override the GXFinishSendPlane message to finish processing of a color plane and send it to your device. Your override of the GXFinishSendPlane message must match the following formal declaration:

OSErr MyFinishSendPlane (void);

function result

An error code. The value noErr indicates that the operation was successful.

DESCRIPTION

QuickDraw GX sends this message to mark the end of a color plane for raster devices that require multiple passes for each page. A film recorder might send this message to mark the end of the red, green, and blue color passes.

QuickDraw GX does not have a default implementation of the GXFinishSendPlane message.

RESULT CODES

gxSegmentLoadFailedErr	A required code segment could not be found, or there was not enough memory to load it.
gxPrUserAbortErr	The user has canceled printing.

SPECIAL CONSIDERATIONS

You can send the GXFinishSendPlane message yourself to mark completion of a plane.

You can totally override the GXFinishSendPlane message to perform tasks at the completion of a color plane pass.
