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 ...
Cairo supports output (including rasterisation) to a number of different back-ends, known as "surfaces" in its code.Back-ends support includes output to the X Window System, via both Xlib and XCB, Win32 GDI, OS X Quartz Compositor, the BeOS API, OS/2, OpenGL contexts (directly [7] and via glitz), local image buffers, PNG files, PDF, PostScript, DirectFB and SVG files.
The size of the vector refers to the actual number of elements, while the capacity refers to the size of the internal array. When new elements are inserted, if the new size of the vector becomes larger than its capacity, reallocation occurs. [1] [5] This typically causes the vector to allocate a new region of storage, move the previously held ...
In computer graphics, swizzles are a class of operations that transform vectors by rearranging components. [1] Swizzles can also project from a vector of one dimensionality to a vector of another dimensionality, such as taking a three-dimensional vector and creating a two-dimensional or five-dimensional vector using components from the original vector.

The first digital computers used machine-language programming to set up and access array structures for data tables, vector and matrix computations, and for many other purposes. John von Neumann wrote the first array-sorting program ( merge sort ) in 1945, during the building of the first stored-program computer . [ 6 ]
The C programming language's bit fields, pseudo-objects found in structs with size equal to some number of bits, are in fact small bit arrays; they are limited in that they cannot span words. Although they give a convenient syntax, the bits are still accessed using bytewise operators on most machines, and they can only be defined statically ...
Modern programming languages that support array programming (also known as vector or multidimensional languages) have been engineered specifically to generalize operations on scalars to apply transparently to vectors, matrices, and higher-dimensional arrays.
vector: a dynamic array, like C array (i.e., capable of random access) with the ability to resize itself automatically when inserting or erasing an object. Inserting an element to the back of the vector at the end takes amortized constant time. Removing the last element takes only constant time, because no resizing happens.
