Description

Returns the default file-name extension of a graphics object.

Call GraphicExtension to obtain a default extension value for the DefaultExt property of an Open, Open Picture, Save Picture or Save dialog. GraphicExtension returns the default extension for the type of graphics object specified by the GraphicClass parameter. In Delphi, the TGraphicClass type is the class type for descendants TGraphic.

These are the file extensions returned for each built-in graphics class:

Graphic class	File extension returned
TBitmap	bmp
TIcon	ico
TMetafile	emf

If custom graphics classes register a file extension, GraphicExtension will return that extension when passed the custom graphics class as an argument.
