procedure RegisterGraphicClass(AGraphicClass: TGraphicClass);

ExpressEditors capable of displaying graphical data (BLOB, Image, etc.) initially support the following graphic data formats:

• Bitmaps (.bmp);

• GIF images (.gif) (*);

• Icons (.ico);

• JPEG images (.jpg and .jpeg) (*);

• Metafiles (.emf and .wmf);

• PNG images (.png) (**);

• TIFF images (.tif and .tiff) (*).

(*) managed by TdxSmartImage.

(**) managed by TdxSmartImage or TdxPNGImage.

Call the GetRegisteredGraphicClasses global function to access the list of graphic classes registered with ExpressEditors. In order to register a new graphic class and add it to the list, call the RegisterGraphicClass global function and pass the graphic class as the AGraphicClass parameter. Once a graphic class is registered, you can use it by specifying its name in editor properties. For BLOB and Image editors, you can accomplish this via the Properties.GraphicClassName or Properties.PictureGraphicClassName property.
