A bitmap graphic may be referred to as a raster graphic.  When viewed at 100%, each dot corresponds to an individual pixel on a display. A file with the .bmp extension is an uncompressed bitmap.  Other raster graphic types, known as compressed bitmaps, include  JPEG, GIF, and PNG.  A bitmap is not a vector graphic.  If a bitmap image is enlarged it will always look blocky because each dot will take up more than one pixel.''Note that although Baseline JPEG lossy compression is what is widely used there are other more obscure implementations including a lossless JPEG (lossless coding mode).  It should also be noted that when using baseline JPEG compression, setting the quality to 100% in software when saving an image still results in image quality loss.  It is not implied that such a setting would switch to a lossless coding mode.''''Note that although Baseline JPEG lossy compression is what is widely used there are other more obscure implementations including a lossless JPEG ([[JPEG lossless coding mode]]).  It should also be noted that when using baseline JPEG compression, setting the quality to 100% in software when saving an image still results in image quality loss.  It is not implied that such a setting would switch to a lossless coding mode.''=== Many Graphic File Formats ===Including proprietary types, there are hundreds of image file types. Some of the formats that are most often used for purposes including web pages, email, digital photography, and desktop publishing are discussed on this page.
