QPx_SetImporterData


importerRef	Longint	Reference to a graphics importer instance
imageData	BLOB	4th Dimension BLOB containing the image data
error	Longint	Error result

Assign image data from a BLOB to a graphics importer

The graphics importer instance is specified by importerRef.

The BLOB holding the image data is specified by imageData.

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

Example

   // Assign image data to the importer

C_LONGINT($error)
C_TEXT($imagePath)
C_BLOB($imageData)

C_LONGINT(gQPixImporter)

$imagePath:="Hard disk:images:people.gif"
DOCUMENT TO BLOB($imagePath;$imageData)

$error:=QPx_SetImporterData (gQPixImporter;$imageData)

If ($error#qpx_noErr)
   
      // Handle the error
   
End if
