For example, on the Android operating system a device-independent pixel is equivalent to one physical pixel on a 160 dpi screen, [1] while the Windows Presentation Foundation specifies one device-independent pixel as equivalent to 1/96th of an inch. [2] As dp is a physical unit it has an absolute value which can be measured in traditional units ...
This Cocoa point is equivalent to the pixel px unit in CSS, the density-independent pixel dp on Android [38] and the effective pixel epx or ep in Windows UWP. Font sizes
The term resolution is often considered equivalent to pixel count in digital imaging, though international standards in the digital camera field specify it should instead be called "Number of Total Pixels" in relation to image sensors, and as "Number of Recorded Pixels" for what is fully captured.
The term display resolution is usually used to mean pixel dimensions, the maximum number of pixels in each dimension (e.g. 1920 × 1080), which does not tell anything about the pixel density of the display on which the image is actually formed: resolution properly refers to the pixel density, the number of pixels per unit distance or area, not ...
Android expresses layout dimensions and position via the density-independent pixel or "dp" which is defined as one physical pixel on a 160 dpi screen. At runtime, the system transparently handles any scaling of the dp units, as necessary, based on the actual density of the screen in use. [13]
(* The pixel number of 6,000x4,000 ist the number of "effective pixels". The sensor usually has a few extra rows of pixels on all four sides, which explains the sensor resolution of 24.3 MPixels often stated, but no information about the exact image size available.) 6,016 4,000 24,064,000 24.1 Nikon D3300 Canon M50: 6,048 4,032 24,385,536 24.4
Pixels per inch (or pixels per centimetre) describes the detail of an image file when the print size is known. For example, a 100×100 pixel image printed in a 2 inch square has a resolution of 50 pixels per inch. Used this way, the measurement is meaningful when printing an image.
DP (complexity), or difference polynomial time, a computational complexity class; Data processing; Software design pattern, a reusable solution to a common problem in software design; Device-independent pixel, a unit representing an abstraction of a pixel for use by an application
