Graphics Functions

Graphics Functions (GDI+)

The Graphics functions provide methods for drawing lines, curves, figures, images, and text. A Graphics object stores attributes of the display device and attributes of the items to be drawn.

Return Values

If the function succeeds, it returns Ok, which is an element of the Status enumeration.

If the function fails, it returns one of the other elements of the Status enumeration.
