A pixel is about anticipation of as the aboriginal audible basic of a agenda image. However, the analogue is awful context-sensitive. For example, there can be "printed pixels" in a page, or pixels agitated by cyberbanking signals, or represented by agenda values, or pixels on a affectation device, or pixels in a agenda camera (photosensor elements). This account is not exhaustive, and depending on context, there are several agreement that are alike in accurate contexts, such as pel, sample, byte, bit, dot, spot, etc. The appellation "pixels" can be acclimated in the abstract, or as a assemblage of measure, in accurate back application pixels as a admeasurement of resolution, such as: 2400 pixels per inch, 640 pixels per line, or spaced 10 pixels apart.
The measures dots per inch (dpi) and pixels per inch (ppi) are sometimes acclimated interchangeably, but accept audible meanings, abnormally for printer devices, area dpi is a admeasurement of the printer's body of dot (e.g. ink droplet) placement.11 For example, a high-quality accurate angel may be printed with 600 ppi on a 1200 dpi inkjet printer.12 Even college dpi numbers, such as the 4800 dpi quoted by printer manufacturers back 2002, do not beggarly abundant in agreement of accessible resolution.13
The added pixels acclimated to represent an image, the afterpiece the aftereffect can resemble the original. The cardinal of pixels in an angel is sometimes alleged the resolution, admitting resolution has a added specific definition. Pixel counts can be bidding as a audible number, as in a "three-megapixel" agenda camera, which has a nominal three actor pixels, or as a brace of numbers, as in a "640 by 480 display", which has 640 pixels from ancillary to ancillary and 480 from top to basal (as in a VGA display), and accordingly has a absolute cardinal of 640 × 480 = 307,200 pixels or 0.3 megapixels.
The pixels, or blush samples, that anatomy a digitized angel (such as a JPEG book acclimated on a web page) may or may not be in one-to-one accord with awning pixels, depending on how a computer displays an image. In computing, an angel composed of pixels is accepted as a bitmapped angel or a raster image. The chat raster originates from television scanning patterns, and has been broadly acclimated to call agnate halftone press and accumulator techniques.
