There is a way to see if someone is really careful when completing a webpage design. Sometimes the miracle is some small details, some details that are almost invisible to others. What I call "pixel-level beauty" refers to the careful scrutiny of online bars, edges, and border strokes. Instead of using a single line, we should add more details. The details can be a subtle gradient, or just a line of 1 pixel

DPI (DPR) stands for dots per inch which technically means printer Dots per inch.This parameter actually quantifies the physical resolution and display sharpness of the screen, such as the iphone's DPR 2, which is higher than the average phone.The same images have a very different effect on different phones, especially for Apple devices, because their DPR are relatively high, so they generally have toApplication of high resolution image display can be

Python and hardware Study Notes: Bluetooth (2) You can also set up the bluetooth module according to the AT command in the Appendix. Next we use the bluetooth module to connect to Raspberry Pi to create a bluetooth wireless communication switch. The mobile phone acts as the

The previous chapter I wrote the rendering pipeline, the middle mentioned the role of shader, our big shader classmate is responsible for the CPU assigned to the GPU to do some such as vertex conversion, care model, rasterization and other operations.There are two types of big shader, they are vs "vertex shader" and Ps "pixel shader".They can exist at the same time, or they can exist separately, without any use restrictions.At that time, if it existed

build a simplest data model, which contains the coordinates of a space point and XYZ, we save and set the pixels. Package{// Basic spatial point ModelPublic class point3d{Public var X: number;Public var y: number;Public var Z: number; Public Function point3d (X: Number, Y: Number, Z: Number){This. x = X;This. Y = y;This. z = z;}}} And then save it as an array. For (var I: Int = 0; I {For (var j: Int = 0; j {VaR color: uint = bitmap. bitmapdata. getpixel (J, I );VaR RED: Int = (color> 16) 0xf

First, we recommend a book: The English version of opencv 2 computer vision application programming Cookbook can be downloaded from the Internet. It seems that there is no translation. This book is characterized by the fact that the program in it is not a process-oriented small program written to demonstrate function functions, but a large program written with an object-oriented approach, but he taught you to write it step by step, and you should not

In a row of two-column layouts, when only one block has a floating property, there is a 3px gap between the two columns (normal for other browsers) under the IE6 browser. As shown in the following:High Version Browser:I in E6:The code is as follows:DOCTYPE HTML>HTMLLang= "en">Head> Metahttp-equiv= "Content-type"content= "Text/html;charset=utf-8" /> title>title> styletype= "Text/css">.

In Bluetooth development, we have the following requirement: Our android client must always be connected to Bluetooth. When Bluetooth has data returned, the android client must collect data in a timely manner, when Bluetooth does not return data, we need to maintain the connection between the android client and

Position pos,unsigned char ch[][6]){draw_position (CH);}4: If there is a for loop for passing a two-dimensional array in the function, you just need to manipulate the two-dimensional array in the definition:for (i=0;ifor (n=0;nif (ch[i][n]==0) ...//ch is the name of the parameter variable when it is defined, and the definition of why it should be written.else ...Well, the basic is finished. In fact, this is very simple, but when the study did not feel this important, simple and past.Later to wr
