Member Function Documentation

convert()

KisImportExportErrorCode KisPDFImport::convert ( KisDocument * document, QIODevice * io, KisPropertiesConfigurationSP configuration = nullptr )

overridevirtual

The filter chain calls this method to perform the actual conversion. The passed mimetypes should be a pair of those you specified in your .desktop file. You have to implement this method to make the filter work.

Returns

The error status, see the #ConversionStatus enum. KisImportExportFilter::OK means that everything is alright.

Implements KisImportExportFilter.
