Member Function Documentation

convert()

KisImportExportErrorCode KisHeightMapExport::convert ( KisDocument * document, QIODevice * io, KisPropertiesConfigurationSP configuration = 0 )

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.

createConfigurationWidget()

KisConfigWidget * KisHeightMapExport::createConfigurationWidget ( QWidget * parent, const QByteArray & from = "", const QByteArray & to = "" ) const

overridevirtual

createConfigurationWidget creates a widget that can be used to define the settings for a given import/export filter

Parameters

parent	the owner of the widget; the caller is responsible for deleting
from	The mimetype of the source file/document
to	The mimetype of the destination file/document

Returns

the widget

overridevirtual

defaultConfiguration defines the default settings for the given import export filter

Parameters
