Public Member Functions

 ThumbnailFilterPNG ()
virtual BOOL DoExport (Operation *pOp, CCLexFile *pFile, PathName *pPath, Document *TheDocument, BOOL ShowOptions)
 Exports a document into a png file. Creates and attaches a DocView to the document before calling the DoExport function of the PNG filter, because it depends on a view being available. Unlike the preview filters no PreviewBitmapSize value is set in this function, so the caller should set it if something different then the default size is required.
