It contains encoded bitmap data so that the downloaded image appears progressively from a blurry picture to the final sharp image. PJPEG files may also fill alternating horizontal lines until the full picture is revealed.
1-bit black and white image; formatted in text format; basic raster image format in which each pixel is represented by a byte that contains a 1 or 0; 1 represents black and 0 represents white pixels.
