retina biometrics

like a scene Many classic Disney movie and animation creation scenarios mean merging different layers. There are exterior layers, unit animation layers, and physical setting layers and top layers obtained through glass painting: this technology is called landscape painting. In many ways, the structure of the experience we create is similar, even if some "layers" far exceed the static visual effects. In fact, they influence how things look based on more complex computations. However, at least

process of creating a bitmap font is relatively easy, and trying to adjust the various knobs, buttons, and colors in the glyph designer does not hurt. The areas that can be edited are indicated below. You can see a list of TrueType fonts on the left side of the diagram, and if not enough, you can load any TTF file using the Load font icon. Below the list, you can use the slider bar to change the font size and apply bold, italic, and other font styles. Tips: Creating a bitmap font t

Look at a lot of information has not been found to have a detailed introduction, including Apple official documents, is also a cursory. It was later seen in a blog that introduced the MacBook print font and was inspired.First, the length unit of the Apple device drawing can be thought of as point, not pound (PT). This point is a logical concept and is device-independent.Figure 1: Different resolution screen display 1pointFor traditional conventional screens, 1 point maps physical screen 1 pixel.

Background: Image-set () The image-set in the css4-images specification can achieve Retina screen display, mainly used to solve the design challenges of Apple Retina screen. In a browser that does not support image-set, it supports background-image images, that is, it does not support image-set browsers, and they parse background images in background-image; Supports image-set: If your browser su

Screen Currently, mobile phone screens on the market are divided into two types: normal screen and Retina screen. The biggest difference between a Retina screen and a normal screen is that the display performance is bett

, the physical pixel/device independent pixel = device pixel ratio (devices pixel ratio), the device pixel ratio of English is DPR, We can get the DPR of the current device through Window.devicepixelratio in JavaScript. So what about the device pixel ratio? The key to this problem boils down to this: 1px in CSS is not equal to 1px in the device. That is, physical pixels and device independent pixels are not the same. In the previous mobile device, such as IPHONE3, its resolution is 320x480 (this

example, 480x800 's screen is made up of 800 rows and 480 columns of pixels. Each point emits a different color of light that forms the picture we see. The physical size of the phone screen is not proportional to the pixel size. The most typical example of the IPhone 3GS screen pixel is the 320x480,iphone 4s screen pixel is 640x960. Just twice times, but two phones are 3.5 inches.So, we're going to introduce one of the most important concepts: pixel density, which is the PPI (pixels per inch).

screen is made up of a lot of pixel points. So many resolutions mentioned before are the actual pixel dimensions of the phone's screen. For example, the screen of 480x800, is composed of 800 rows, 480 columns of pixel points. Each point emits a different color of light that constitutes the picture we see. And the physical size of the phone screen is disproportionate to the size of the pixel. The most typical example of the IPhone 3GS screen pixel is the 320x480,iphone 4s screen pixel is 640x960

Optimization of ecosystem and third party software vendors Another problem is the software problems caused by ecosystems. Similar to the first reason, software vendors are not able to use a variety of Windows notebook resolution with a special icon and other materials, so on a high-resolution screen, only through the DPI-scale low-resolution software, ther
