A pixel is a dot that represents the smallest graphical measurement on a screen. Twips are the default unit of measurement in Visual Basic (version 6 and earlier, prior to VB.NET). Converting between twips and screen pixels is achieved using the TwipsPerPixelX and TwipsPerPixelY properties [ 3 ] or the ScaleX and ScaleY methods.
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.
[1] [2] In the case of an RGB color display, the derived unit of pixel pitch is a measure of the size of a triad plus the distance between triads. Dot pitch may be measured in linear units (with smaller numbers meaning higher resolution), usually millimeters (mm), or as a rate, for example, dots per inch (with a larger number meaning higher ...
The aspect ratio also affects the perceived size of objects on the screen. [5] The native screen resolution together with the physical dimensions of the graphics display can be used to calculate its pixel density. An increase in the pixel density often correlates with a decrease in the size of individual pixels on a display.
One of the simpler ways of increasing the size, replacing every pixel with a number of pixels of the same color. The resulting image is larger than the original, and preserves all the original detail, but has (possibly undesirable) jaggedness. The diagonal lines of the "W", for example, now show the "stairway" shape characteristic of nearest ...
Thus, for example, a 10-point font on a Macintosh (at 72 PPI) was represented with 10 pixels (i.e., 10 PPEm), whereas a 10-point font on a Windows platform (at 96 PPI) at the same zoom level is represented with 13 pixels (i.e., Microsoft rounded 13 + 1 ⁄ 3 to 13 pixels, or 13 PPEm) – and, on a typical consumer grade monitor, would have ...
A device-independent pixel (also: density-independent pixel, dip, dp) is a unit of length.. A typical use is to allow mobile device software to scale the display of information and user interaction to different screen sizes.
Four times as many pixels compared to the base resolution, i.e. twice the horizontal and vertical resolution respectively. Hex(adecatuple) (H) Sixteen times as many pixels compared to the base resolution, i.e. four times the horizontal and vertical resolutions respectively.
