Dpi, ppi, dip, dp, px, sp, dpippi Basic Concepts 1. dpi (dots per inch): The number of dots per inch; ppi (Pixel per inch): The number of dots per inch. Designed for the monitor, dpi = ppi. 2. dip (device independent pixels) devices are independent pixels. Different devices have different display effects, which are related to device hardware and do not depend

Turn to the user's answer:1. DPI is the dot per inch, how many dots, PPI is Pixel per inch, pixels per inch, for the design of the display, Dpi=ppi.The PPI calculation method is the sum of the length and width of each square, divided by the diagonal length (in inches). Principle can draw a rectangle of the Pythagorean theorem to calculate a calculation.2. PPI indicates the point density of the display devic

Conceptual interpretation Noun Explain Px(Pixel pixels) Different devices show the same effect. The "Same" here means that the number of pixels does not change, such as specifying a UI length of 100px, regardless of the resolution of the UI length is 100px. This is why the UI is magnified and distorted on small-resolution devices, and is scaled down at large resolutions. Screen Size(Screen size) Generally speaking, the size of a mobile pho

Concept:DPI (dots per inch): points per inch, initially used to measure the density of dots per inch on the print, and how many points the printer plays in an inch. The smaller the DPI value, the less fine.PPI (Pixels per inch): The number of pixels per inch, when the concept of DPI is used on an electronic screen, it should be called the PPI.For developers, DPI

Length Unit In typography, "point" is an absolute unit that is equal to 1/72 inches and can be measured by a ruler, in physical inches. But the meaning of PT in CSS is not so, for example, we specify a font is 9PT, we would think that according to the CSS specification, it is equal to: 9 * 1/72 = 1/8 inch This is a misunderstanding, because our display is divided into pixels, a single pixel can only have one color (for simplicity, the pixel anti-aliasing technique is not discussed here), to be

1. px (pixels) pixels-is a pixel, which is the actual pixel unit on the screen. Dip or dp (device independent pixels) device independent pixels, related to the device screen. Sp (scaled pixels-best for text size): similar to dp, it mainly deals with the font size. Dpi (dot per inch): screen pixel density, how many pixels per inch There is a member with the same name in the android api. The method is as follows: 2.

Http://doc.qt.io/qt-5/highdpi.htmlQt Support Ability to provide pixmaps or artwork for high Resolution:see Drawing High resolution Versions of Pixmaps and Images. Qt 5.4 introduces experimental support for scaling by-device pixel ratio similar to OS X to the platform plugins for Wi Ndows and Unix (XCB). This was controlled by the environment variable QT_DEVICE_PIXEL_RATIO . It can be set to a numerical value to being used as scale factor or "auto" which causes the scale factor to be

With technology in power generation, many PCs or tablets are now configured with high-resolution display screens, and many friends will set up a larger DPI (especially on a small size screen) to make the fonts on the screen look clearer when Windows is installed. Although some software interfaces may have blurred problems after setting a larger dpi, some settings allow them to be displayed in their original
