How is bitmap image stored on a computer?

A bitmap is a method for storing images using pixels. This information is stored as a sequence of numbers defining the colour of each pixel. In a simple black and white image, a bitmap just needs to know if a pixel is ‘on’ or ‘off’, which can be stored as 1 or 0.

How are bitmap and vector images stored?

Bitmap (or raster) images are stored as a series of tiny dots called pixels. Each pixel is actually a very small square that is assigned a color, and then arranged in a pattern to form the image. A vector image just has to store the mathematical formulas that make up the image, which take up less space.

How are vector graphics stored in a computer?

Vector graphics are stored as a list of attributes. Rather than storing the data for each pixel of an image, the computer will generate an object by looking at its attributes. This would often happen by simply increasing the size of the image by using the pointer within a graphics package.

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.

How data for a vector graphic is represented and encoded?

A vector image uses scalable shapes such as straight lines and curves, using coordinates and geometry to precisely define the parts of the image. It is more efficient than bitmaps at storing large areas of the same colour because it does not need to store every pixel as a bitmap does.

How is an image encoded?

Digital images are encoded in binary. Students make connections between the amount of data used by the computer to store, transmit and create an image and the file size of different images (generally, the more pixels and more bits to encode the image, the larger the file size).

How is graphic data stored?

Definition: Graphic images are stored digitally using a small number of standardized graphic file formats, including bit map, TIFF, JPEG, GIF, PNG; they can also be stored as raw, unprocessed data. This is because all those images are stored in what amounts to a handful of file formats.

How are vector graphics represented?

Vector graphics is the use of polygons to represent images in computer graphic designs. Vector graphics are based on vectors, which lead through locations called control points or nodes. Vector-based images are not made up of a specific number of dots, they can be scaled to a larger size and not lose any image quality.
