I want to achieve the effect: But the designer gives this:.The first thing I think about is that this is like the Windows computer settings wallpaper has what stretch, adaptive, tile and other types, this should be the legendary tile bar.Then we know that an ordinary button, set his background, is nothing more than setbackgrounddrawable/resource/color these kinds of methods can be called in the method can n

Literal meaning: linear mode and Block Mode In the early game design, tile is called the block mode, which is the basic unit of map. A map consists of multiple tile. tile is much larger than pixel. Generally, the width and height are equal and the power of 2. Early game pictures were relatively dull, and there were a lot of duplicates.

09th-dynamic tile: Today, let's learn a very important thing: Dynamic tile. In the previousArticle, As I mentioned, the tile isProgramThe success is an important part, and the tile is the most easily overlooked part.Your tile represents the relationship between you and the

Microsoft WIN8 System Start screen dynamic magnetic paste can display a lot of information, such as news, microblogging, weather and so on, but sometimes the magnetic paste on the display is not the latest dynamic information, some of the information has been read also retained on the magnetic paste. Can we set up to let the WIN8 system not push the expiration of the dynamic tile notification information? Of course, the method is also very simple, you

During game development, we will encounter maps that exceed the screen size, such as real-time strategic games, so that players can scroll the game screen in the map. This type of games usually have rich background elements. If you directly use the background image switching method, you need to prepare a background image for each different scenario, and each background image is not small, which will cause a waste of resources. Tile maps are generated

The Android implementation Windows 8 Tile Style buttonAs follows:I'm streamlining and sorting out a simple class based on the code I've circulated online, and I'm naming it for the moment: Windows8tileimageview, the Windows 8 Tile Style button, Windows8tileimageview is actually inherited from the standard Android ImageView, click on the Windows8tileimageview with shrinkage, side shrinkage and other more int

and the traditional Win7 system is somewhat different, in the Win8 operating system with "Start screen" instead of the original familiar "Start" menu, this change makes many user operation difficult to adapt, but accustomed to the operation after you will find the function of the start screen is also very wonderful, We can add commonly used program applications to the Start screen tiles, this can be more convenient to open and use, but in the magnetic paste will remain a variety of information,

The projection method of Google map slices and the index mechanism of tiles1. Map projectionGoogle Maps uses a web Mercator projection (such as), in order to conveniently ignore the regions with large polar deformation, the world map is made into a square with a side length equal to the equator circumference (the equator length is 6378137 meters), the origin in the center of the square, that is, longitude and latitude (0,0). The value of the x, Y coordinates of the Web Mercator projection is: [

First, prefaceLive tiles are featured in WindowsPhone8.1 and Windows8.1, and some people like to hate it, but I think it's good to let users quickly know what's inside the app and entice users to open the app. Below to learn how to add live tile, actually quite simple.Second, the tile template (tile ' s templates)The tiles on the windows8.1 and the tiles on the w

The tile function is in the Python module numpy.lib.shape_base, and his function is to repeat an array. For example, Tile (a,n), the function is to repeat the array a n times to form a new array, we still use specific examples to illustrate the problem:Let's start by introducing all the methods under NumPy:>>> from numpy Import *We create a, use tiles to create B, and look at the data structure of B:>>> a=[
