Basic Terms Related to Raster Graphics
Here the some basic terms of the raster graphics.
- Pixel: In computer graphics, an actual point in a picture is called a pixel, dot, or image element. Pixels are the smallest addressable units in an image that is shown on a screen. Almost everything we see on computer displays is composed of raster graphics. A selfie taken with your phone is an example of a raster image as well. To make an image, a bitmap, or collection of pixels, is utilized.
- Bitmap: A bitmap in computer graphics is a mapping between a domain and bits, or values that can only have one or zero values. There are other names for it, such as bit array or bitmap index. More broadly speaking, a “pixmap” is a map of pixels that have more than two colors stored in each pixel, or more than one bit per pixel. For that too, the bitmap is widely employed. The phrase “bitmap” refers to one bit per pixel in certain situations, whereas pixmap is used for images with several bits per pixel.
What is Raster Graphics?
Computer Images are made up of a bitmap or grid called the “raster graphics” Raster graphics make up the majority of images on the web and on our computer. They are one of the two main picture types used in vector graphics on computers. A raster graphic’s file size relies on a number of factors. The first is the raster graphic’s resolution or the size of the image in terms of pixels.
