When zooming in or enlarging a bitmap image, the pixels are stretched and made into larger blocks. This is why bitmap images appear as poor quality when enlarged too much. Each colour of an image is stored as a binary number. In the black-and-white image below, each pixel is either black or white.

How are bitmap graphics stored and represented?
Bitmapped graphics are most commonly created by taking a photo with a digital camera (or mobile phone camera). The image will be stored as a grid of pixels, where each pixel is a digital representation of a colour that was captured by the camera's photo sensors.
What is bitmap storage?
In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits. ... In some contexts, the term bitmap implies one bit per pixel, while pixmap is used for images with multiple bits per pixel. A bitmap is a type of memory organization or image file format used to store digital images.
Where are bitmap graphics stored?
All bitmap images are stored in the computer as a rectangular grid of pixels. The resolution of an image refers to the number of pixels in the grid; higher resolutions mean that more details can be stored in the image.
What does a bitmap image contain?
Bitmaps images are exactly what their name says they are: a collection of bits that form an image. The image consists of a matrix of individual dots (or pixels) that all have their own colour (described using bits, the smallest possible units of information for a computer).
How does a bitmap represent an image?
Bitmap images are made up of individual pixels. The colour of each pixel is represented as a binary number so the whole image is therefore stored as a series of binary numbers. In the example on the right the animation zooms into the small image to show the individual pixels.
What is bitmap data?
bitmap, method by which a display space (such as a graphics image file) is defined, including the colour of each of its pixels (or bits). In effect, a bitmap is an array of binary data representing the values of pixels in an image or display. A GIF is an example of a graphics image file that has a bitmap.
What is bitmap tutorial?
A bitmap is a mapping from one system such as integers to bits. It is also known as bitmap index or a bit array. The memory is divided into units for bitmap. These units may range from a few bytes to several kilobytes. ... So there entry in the bitmap is 11111.
How or where are bitmap files usually used?
Short for "Bitmap." It can be pronounced as "bump," "B-M-P," or simply a "bitmap image." The BMP format is a commonly used raster graphic format for saving image files. ... This method of storing image information allows for crisp, high-quality graphics, but also produces large file sizes.
How is an image stored in a computer?
Images are stored in the form of a matrix of numbers in a computer where these numbers are known as pixel values. These pixel values represent the intensity of each pixel. 0 represents black and 255 represents white.
What is the difference between bitmap and vector?
A bitmap (also called "raster") graphic is created from rows of different colored pixels that together form an image. ... Rather than a grid of pixels, a vector graphic consists of shapes, curves, lines, and text which together make a picture.
What is the information stored in a digital picture called?
This contains information called “metadata” that describes data about the data. This data pertains to specific details that are often set by the camera vendor. This includes information like camera model, white balance, ISO, aperture, shutter speed, photo editing software used on the image, etc.
How pixels are stored?
Typically, the pixels are stored in computer memory as a raster image or raster map, a two-dimensional array of small integers. These values are often transmitted or stored in a compressed form.
How are raster images stored?
A raster is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats.
