Encapsulates a GDI+ bitmap, which consists of the pixel data for a graphics image and its attributes. A bitmap is an object used to work with images defined by pixel data.
bitmap(const xtd::drawing::image &original)
Initializes a new instance of the bitmap class from the specified existing image.
An abstract base class that provides functionality for the bitmap and metafile descended classes.
