Returns the image data associated with a graphics importer instance.

If importerRef is not associated with a BLOB, or if it does not refer to an existing graphics importer instance, the qpx_paramErr error code is returned.

Example

  `Get the image data associated with the importer
 
C_LONGINT($error)
C_BLOB($imageData)
 
C_LONGINT(gQPixImporter)
 
$error:=QPx_GetImporterData (gQPixImporter;$imageData)
 
If ($error#qpx_noErr)
   `Handle the error
End if
