QPx_SetImporterData

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

Assigns the image data contained in a 4D BLOB to a graphics importer instance.

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
