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.

The following code example demonstrates how to construct a new Bitmap from a file, using the GetPixel and SetPixel methods to recolor the image. It also uses the PixelFormat, Width, and Height properties.

Bitmap images are commonly associated with file formats such as BMP, JPEG/JPG, PNG, GIF, and TIFF. BMP is the standard bitmap format, typically uncompressed and known for its large file size.

2025年6月1日 · What is a Bitmap? A bitmapped graphic is a digital image where every pixel is represented by a set number of bits. When describing a bitmap file format, bitmap files often end with the file extensions of *.bmp or *.dib (device-independent bitmap) …

2014年2月6日 · Bitmap Definition - What is a bitmap image? 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 …

For gray scale or color, several bits in the bitmap represent one pixel. The term may refer to the image itself or to the memory area that holds the bits that represent the image.

2025年2月19日 · A bitmap is a digital image made up of countless tiny, colored dots called pixels. Learn more about bitmaps and how they compare to other image formats here!

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.

Bitmap graphics are the images made up of tiny dots called pixels (picture elements). These pixels are arranged in a grid or matrix, and each pixel represents a single color.
