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 bits. Now, along with pixmap, it commonly refers to the similar concept of a spatially mapped array of pixels.

Feb 6, 2014 · A bitmap (or raster graphic) is a digital image composed of a matrix of dots. When viewed at 100%, each dot corresponds to an individual pixel on a display. In a standard bitmap image, each dot can be assigned a different color.

Each memory unit is associated with a bit in the bitmap. If the unit is occupied, the bit is 1 and if it is empty, the bit is zero. The bitmap provides a relatively easy way to keep track of memory as the size of the bitmap is only dependent on the size of the memory and the size of the units.

The BMP file format, or bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter), especially on Microsoft Windows [2] and OS/2 [3] operating systems.

What Is a Bitmap Image? A bitmap image is a digital image format that is comprised of a grid of pixels, each of which represents a specific color that, when combined, create an image. The term “bitmap” comes from the fact that the image is mapped onto a grid of pixels, with each pixel representing a small portion of the image.

A bitmap is a digital image format that uses a grid of tiny dots, called pixels, to create a picture. Each pixel contains color information, and when viewed together, they form a complete image. Bitmaps are commonly associated with the .bmp file extension, though they can also use .dib (device-independent bitmap).

Bitmaps are defined as a regular rectangular mesh of cells called pixels, each pixel containing a colour value. They are characterised by only two parameters, the number of pixels and the information content (colour depth) per pixel. There are other attributes that are applied to bitmaps but they are derivations of these two fundamental parameters.

Sep 1, 1996 · What is a bitmap? A bitmap is a file format or memory organization of rows and columns of bits (or pixels) that collectively display a graphical representation. Most graphic images contain thousands of bits.

Apr 7, 2025 · A graphic file format with the file extensions of *.bmp or *.dib (device-independent bitmap) used in Microsoft Windows and OS/2. Bitmap images can be saved as either 4-bit (16 colors), 9-bit (256 colors), 16-bit (65,536 colors), or 24-bit (16.7 million colors) and saved as uncompressed images.

Apr 2, 2025 · The more colours and more detail in the image, the higher the quality of the image and the more binary that needs to be stored. Image vs screen resolution. Image resolution is the total amount of pixels that make up a bitmap image. The image resolution is calculated by multiplying the height and width of the image (in pixels). In general, the higher the resolution the more detail in the image ...
