Get the image data associated with a graphics importer
The graphics importer instance is specified by importerRef.
The image data assigned to importerRef is returned in imageData.
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
