Returns a reference to the graphic importer instance used internally by a QPix plug-in area.
This is a low-level command. It gives access to the image characteristics and data through the QPix Graphics Importer API.
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.
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 |
