The word pixel is a combination of pix (from "pictures", shortened to "pics") and el (for "element"); similar formations with ' el' include the words voxel [4] 'volume pixel', and texel 'texture pixel'. [4] The word pix appeared in Variety magazine headlines in 1932, as an abbreviation for the word pictures, in reference to movies. [5]
Scanners and cameras. "PPI" or "pixel density" may also describe image scanner resolution. In this context, PPI is synonymous with samples per inch. In digital photography, pixel density is the number of pixels divided by the area of the sensor. A typical DSLR, circa 2013, has 1–6.2 MP/cm 2; a typical compact has 20–70 MP/cm 2.
Some types of pixel layout showing how pixel pitch is measured. Dot pitch (sometimes called line pitch, stripe pitch, or phosphor pitch) is a specification for a computer display, computer printer, image scanner, or other pixel -based devices that describe the distance, for example, between dots (sub-pixels) on a display screen. [1][2] In the ...
Dots per inch (DPI, or dpi[1]) is a measure of spatial printing, video or image scanner dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm). Similarly, dots per centimetre (d/cm or dpcm) refers to the number of individual dots that can be placed within a line of 1 centimetre ...
When the link is clicked the image is displayed with other text information at a reasonable size. The user can click through the resulting medium-sized image to get to the full size highest resolution image. You can also send the user directly to the image: [[Media:Wikipedesketch.png]] Media:Wikipedesketch.png. This says Media: instead of File ...
Image resolution. Image resolution is the level of detail of an image. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved.
The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, [1][2] when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers ...
Image using width upright=1.8, so that it is 80% wider than the Siberian Husky image above (which is at the default upright=1 width) Image using upright=0.5; a scaling factor less than 1 contracts the image width. An image's size is controlled by changing its width – after which software automatically adjusts height in proportion.
