GraphicExtension function

Declaration

function GraphicExtension(GraphicClass: TGraphicClass): string

Description

Calls GetPicFileFormats to get the list which maps TGraphicClass (or descendent) references to a file extension.

GraphicExtension iterates over the values in the mapping list in reverse order, and compares the class name for the list item to the class name in GraphicClass. When a match is found, the GetFormatExt method for the item is called to get the return value for the function.

The return value is an empty string ('') when a mapping for GraphicClass is not found in the list.
