In computer graphics, when the domain is a rectangle, a bitmap gives a way to store a binary image, that is, an image in which each pixel is either black or white. Therefore, most images you see on the web are compressed bitmaps. If you zoom into a bitmap image, regardless of the file format, it will look blocky because each dot will take up more than one pixel. Il s'agit donc d'une juxtaposition de points de couleurs formant, dans leur ensemble, une image. Quâest-ce quâune image Bitmap?
