Python does not come with any built-in bit array data type but there is a third-party package called bitarray. [9] Rust does not come with any built-in bit array data type but there are third-party packages such as fixedbitset. [10]
In some contexts, the term bitmap implies one bit per pixel, whereas pixmap is used for images with multiple bits per pixel. [3] [4] A bitmap is a type of memory organization or image file format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatially mapped array of ...
Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7. [3]
The compact trie node representation uses a bitmap to mark every valid branch – a bitwise trie with bitmap. The AMT uses eight 32-bit bitmaps per node to represent a 256-ary trie that is able to represent an 8 bit sequence per node.
A binary image can be stored in memory as a bitmap: a packed array of bits. A binary image of 640×480 pixels has a file size of only 37.5 KiB, and most also compress well with simple run-length compression. A binary image format is often used in contexts where it is important to have a small file size for transmission or storage, or due to ...

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 .
ICO and CUR files contain bitmaps starting with a BITMAPINFOHEADER. Many older graphical user interfaces used bitmaps in their built-in graphics subsystems; [25] for example, the Microsoft Windows and OS/2 platforms' GDI subsystem, where the specific format used is the Windows and OS/2 bitmap file format, usually named with the file extension ...
