What is a pixel? What is DPI? (Dots Per Inch) You may think you don't know what a pixel is, but, If you've ever seen a card stunt at a sports event, you probably do! A pixel is simply the individual point of color on a digital image. A pixel doesn't have a particular size. This same concept extends to many other digital products. Pixel indicates only a point on a grid, not the size of the point. For Printers and scanners, the individual points of color are often called 'dots' rather than pixels, but the concept remains the same as the stadium. The scanner performs this function in reverse, by recognizing the color at a specific row and column on the item being scanned.
