GdiPlus Enumerations

The 74 public enumerations of the package, in groups by topic. The members of an enumeration can be written with or without the name of the enumeration, as in FillModeWinding or GpFillmode.FillModeWinding.

Most of them are GDI+ enumerations, with the names and the values of the GDI+ header files, and a Gp in front of the name of the ones whose name a class of the package uses. CColor, GraphicsCreationOptions, GraphicsFlags, FillStyleConstants and GpErrorHandlingStrategy belong to the package.
