Meaning – Bitmap refers to a digital image that is comprised of a matrix of dots. The speciality of a bitmap is that each dot in the matrix can be assigned a specific colour. When these dots are put together, they come together and form any type of rectangular picture.
Traditionally, a bitmap file is assigned the ‘.bmp’ extension, but in the market, there are various other extensions that are used as well.
Bitmap images are raster style images, which means that the image will appear blocky when you zoom in too much. This is because bitmap files are composed of individual dots, and these dots will appear separately, the more you zoom into the image. If you are looking for a lossless image, the alternative, is a vector image.
Example of Usage – “He wanted to figure out a way to convert his raster style bitmap image, into a lossless vector style image”.
