Get a reference to the graphic importer used by a QPix area
The plug-in area is referenced by areaRef. If areaRef is not a valid QPix plug-in area reference or if it is not currently using a graphics importer instance, qpx_paramErr error is returned.
Parameter importerRef receives the reference to the importer instance used by the area.
NOTE This is a low-level command. It allows access to the image characteristics and data through the QPix Graphics Importer API.
Example
// Get the area importer C_LONGINT($error) C_LONGINT($areaImporter) $error:=QPx_GetAreaImporter (gQPixArea;$areaImporter) If ($error=qpx_noErr) // $areaImporter is the importer used internally by gQPixArea End if
