"using" to avoid type name conflicts
You already know that in a *. CS file, you can use the using keyword to direct the compiler to a complete type name. However, you may not know that you can use the using keyword to create aliases (which helps avoid name conflicts ). Assume that you have two namespaces:
Namespace my2dshapes {public class hexagon {}} namespace my3dshapes {public class hexagon {}}
As

There are a lot of classmates recently. Ask me questions about honeycomb polygons. That is, the hexagon, which is the following stuff:General question and answer modes such as the following:Pro Q: What is the tool in ArcGIS that can do this stuff?Shrimp God Answer: Well, there is no original tool.The parents asked: "Then I see very many people have done ah, this East how to do?"Shrimp God Answer: Well, the algorithm is very easy ...

The DOM definition leverages the interface and inheritance of different components of an XML document. This gives developers the advantage of using a common interface for several different types of components, but adds complexity to the API. Because the DOM is language-independent, the interface does not need to take advantage of public Java components, such as the collections class.
This article covers two DOM implementations: Crimson and Xerces
In the tutorial I will show you how to create a hexagon background blur effect. We will use brushes, patterns, blending modes, and basic filters to achieve this effect.

Step 1
Open Photoshop, create a new document, I'm using 2560x1440 pixels, and I can use it as a wallpaper. Fills the background with a dark gray (#181818). (Figure 01)

You can link to the download page from the resources section at the bottom of this page to get the complete code for all samples. The download version of the sample includes a test driver and some added code to check the operations of different models by calculating the number of elements, deletions, and additions.

The center point and the edge length of the positive hexagon are known, the coordinates of each vertex are obtained, and the correlation algorithm is given.Using the specificity of a positive hexagon:1, the center point and the vertex line constitute a positive triangle2. Each vertex falls on a circleIdea: To find a special case, the upper and lower 2 vertex lines parallel to the Y axis, the other case of t
