Assigns a graphics importer instance to a QPix plug-in area.
The graphics importer reference importerRef must be a valid importer instance created with one of the importer creation commands (QPx_NewImporterForFile, QPx_NewImporterForData, QPx_NewImporter).
If the importer is succesfully assigned, the area takes its ownership. This means that you don't have to call QPx_FreeImporter to destroy the importer instance; it is freed when the area is destroyed by 4D or when another command changes the area's content data.
Example
`Assign an importer to a QPix area C_LONGINT($error) C_LONGINT(gQPixImporter) $error:=QPx_SetAreaImporter (gQPixArea;gQPixImporter) If ($error#qpx_noErr) `Handle the error End if |
