What is the difference between GDI and GDI+?

Question

Are there any differences between those two libraries?

Answer 1

From Wikipedia:

GDI+ adds anti-aliased 2D graphics, floating point coordinates, gradient shading, more complex path management, intrinsic support for modern graphics-file formats like JPEG and PNG, and support for composition of affine transformations in the 2D view pipeline. GDI+ uses ARGB values to represent color.
