Inheritance diagram for PreviewFilterBMP:
Public Member Functions | |
PreviewFilterBMP () | |
Constructor for an PreviewFilterBMP object. The object should be initialised before use. | |
BOOL | Init () |
Initialise an PreviewFilter object. | |
virtual BOOL | DoExport (Operation *, CCLexFile *, PathName *, Document *, BOOL) |
Do some set up before exporting so the BaseBitmapFilter base class knows it is really a preview. The BaseBitmapFilter can then do resizing as necessary. | |
Protected Member Functions | |
virtual BOOL | GetExportOptions (BitmapExportOptions *pOptions) |
Override base class so we don't put up a dialog but still provide fixed options for preview bitmap filters. Notes: See BaseBitmapFilter for interface details. | |
Private Member Functions | |
