Among these basic concepts of Screen, dip is the most important, and dip is the key to understanding android adaptation to different devices.
Screen Size
Actual physical size. This is what we often call 3.5 inch screens and 4.7 inch screens. This length is the diagonal line length. In android, the physical size of the screen is divided into the following categories: small, normal, large, extra large. The following is a rough classification of the size and density. This figure may be updated as t
spectrum, but this spectrum does not contain all the information in the time domain. Because the spectrum represents only the amplitude of each corresponding sine wave, without mentioning the phase. The fundamental sine wave a.sin (wt+θ), amplitude, frequency, phase integral, different phase determines the position of the wave, so for the frequency domain analysis, only the spectrum (amplitude spectrum) is not enough, we also need a phase spectrum. So where is this phase spectrum? We see, this

A triangular number is the number of dots in an equilateral triangle uniformly filled with dots. For example, three dots can be arranged in a triangle; thus three is a triangular number.N-ThTriangular number is the number of
PPI values represent the display's ability to display images at higher densities. The higher the density shown, the higher the fidelity.
DPI (dots per inch): Print counting unit, which is the number of dots per inch that can be printed. One of the main parameters that measure the printer's printing accuracy, the higher the value, the higher the printer's print accuracy. PPI=DPI on the electronic screen
Basic ideas:1) Detect finger slide direction: Get the position when the finger is lifted, minus the position when the finger is pressed, it is going to slide.2) When the finger is lifted, change the position of the current page to the corresponding reverse operationThe specific code is as follows:HtmlCss*{margin:0;padding:0; }Body{Overflow:Hidden; }#wrap > Div{width:10rem;position:Absolute; Left:0;Top:0;background:#fff;transition:All 0.3s Ease; }#dots
noise (point swap, Index swap) to the same pattern, the less sensitive it is, the better the effect.The horizontal axis indicates the rate of noise addition, and the ordinate indicates the distance from the original pattern vector. The black dots represent the distance between the vector and the original pattern vector of different patterns of pattern, and the red dots indicate the average distance, which
If, without the translation of purple books, I think I may not understand the problem. =_=||Test instructionsThere are n points on the plane, not white dots or black dots. Now put a straight line so that the white point on one side of the line and the black point on the other side add up to the highest number. A point on a line can be considered to be on either side of a line.Analysis:First assume that the

Totalcart = function () {var Total = 0;for (var i = 0, Len = $scope. items.length; l Note: in Totalcart () establish a watch, Totalcart () is used to calculate the total amount of the payment, and whenever it changes, the Watch function calls Calculatediscount (), and we set the appropriate discount for that value. If the total value Da Yu 100$, set the

This PS build technology Light Point Shading Tutorial personally feel is a very good primer tutorial, difficult, suitable for just beginning to learn PS friends to learn. Recommended to fly with friends to share their studies.
Let's take a look at the final effect chart:
TIPS: Note that this article is about making the background texture behind the ring, not the ring!

1. Put two small point arm pictures and head pictures in a view.
2. Put those two long arms into a view, and then stack the view on the view in 1, where the position corresponds, the hand just can cover the eyes, the view of the property to set to more than part of the automatic cropping. View color is transparent.

Make an active page seconds kill list page need a time algorithm sort myself pondering for a while to think of a variety of algorithms did not get out, later asked the next backstage PHP classmate he wrote an algorithm for me to see the next, just start to see that this is a pure algorithm, can not be converted into a page of the DOM effect, But saw two times to find can, so I changed the change, realized, first share to everyone.
Page requirements are: from 11 to 20 point every one hours a sec
(that is, a written shape), we define it in black. Remember how to set the foreground black in the quickest way? The answer is to press D.
Step 4: Draw the pen shape
Basically, we want the written shape to be a fragmented size star, of course we can draw each star ourselves, but if there is a shortcut, why not take the shortcut? Luckily, some of the brushes built in Photoshop are very much like stars, and we find one in the existing brush, one in the West, To make a new brush of h
Now the consumer electronic devices screen more and more small, but the resolution is increased, such as Surface pro,10.6 inch screen, 1080p Full HD display, will make Windows display text becomes unusually small. This phenomenon is due to the fact that the screen dot pitch is smaller than the standard (about 207.82 dots per inch, the standard is about 96 dots per inch), but the display is more subtle, but

Create a new PS file with white canvas. In this example, with 580x300px, resolution 72DPI, it is recommended to do this on a larger canvas, so that there is more room to play.
Step 2
Create a new layer. Grasp the Brush tool (B), turn on the Brush option (Window > Brush/or Keyboard function key F5 by pressing D to set foreground color, using the settings of the brush setting options. Start with a regular round brush. Depending on the size of
The tutorial introduces very lifelike methods of making stone. The general process: first with a brush or selection tool to do some white oval to fill the canvas, and then with the liquefaction filter deformation processing, the ellipse painted an irregular shape. OK after the appropriate blur and add layer style, basically the effect came out.Final effect1, create a new document in Photoshop, random size, black background. In this tutorial, my size is 550px x 300px (at the same width).2. Make s
