    Inherits Drawing

Inheritance:

UnknownDrawing

Remarks

This type can either represent some drawing that is supported by a particular input file format supported by the GemBox.Presentation component or some user-defined drawing. In either case, drawing is not supported by the GemBox.Presentation component (no additional behavior or information about it can be obtained through the GemBox.Presentation API).

This type is used for preserving not supported drawings when reading and writing a presentation to the same file format.

This type can also be used for user-defined drawings, although GraphicFrame type is more appropriate for this purpose.

Information contained in the Data property is either internal to GemBox.Presentation component (when the type is used for preserving not supported drawings) or is user-specific type (when the type is used for user-defined drawings).
