The Skia Graphics Engine or Skia is an open-source 2D graphics library written in C++. Skia abstracts away platform-specific graphics APIs (which differ from one to another). [ 1 ] Skia Inc. originally developed the library; Google acquired it in 2005, [ 2 ] and then released the software as open source licensed under the New BSD free software ...
The library loaded graphic drivers (*.BGI) and vector fonts (*.CHR) from disk in order to provide device independent graphics support. It was possible for the programmer to embed the graphic driver into the executable file by linking the graphic driver as object code with the aid of a utility provided by the compiler (bgiobj.exe).
The development of fast methods for various bit blit operations gave impetus to the evolution of computer displays from using character graphics to using raster graphics (bitmap) for everything. Machines that rely heavily on the performance of 2D graphics (such as video game consoles) often have special-purpose circuitry called a blitter.

Security is typically managed by accessing the caller stack programmatically: Since callers() is a list of the methods by which the current verb was eventually called, performing tests on callers()[0] (the command invoked by the original user) allows the verb to protect itself against unauthorised use.
Various free and open-source canvas or scene-graph libraries allow developers to construct a user interface and/or user-interface elements for their computer programs. Examples of free and open-source scene-graph canvas options include: in C, Evas (in EFL) from the Enlightenment project; in C, Clutter, associated with the GNOME project
By employing these functions, a program can assemble an image to be output to a monitor. This relieves the programmer of the task of creating and optimizing these functions, and allows them to focus on building the graphics program. Graphics libraries are mainly used in video games and simulations.
