1. Select the face layer, choose the path of the mouth as a guide or directly to create a constituency can achieve the purpose, and then use the deepening tool to deepen the surrounding and upper and lower lip flap connection, Dodge tool to wipe out the high light area, mouth with sponge tools appropriate suction color 2. The mouth path creates a selection, creates a new mouth layer, fills the pink tone and then a Gaussian blur. Use an eraser to remove excess parts. Lip line to loom

Vector or arraylist-which one is better? Why? The answer to this question cannot be generalized. Sometimes it is better to use vector. Sometimes it is an arraylist. Sometimes neither of them is The best choice. Don't expect a simple affirmative answer, because it depends on what you use them. Four of the following are to be considered: Factors: L API L synchronous processing L data growth L usage mode We wi

Today, I have nothing to do with it. I 've been reading about it for a long time on my computer. When I saw 43rd entries, I found that, as mentioned above, the algorithm replaces the manual loop. No doubt arises. I remember the operator [] operation (subscript operation) was the most efficient loop when I read the vector source code ). The algorithm is fast. The following is a test code: // Test class and call Function Class AAA{Public:Void MakeFul

C ++ Study Notes (15th): How the vector object grows in the memory space, learning notes vector How does a vector object increase in memory? We all know that vector objects are dynamically stored. From this point of view, they are a bit like linked lists, which can dynamically increase or decrease elements. We also kn

Vector series in practice c ++ -- use std: find and std: find_if algorithms for vector (custom class) Previously, my blog talked about some usage of std: find and std: find _ if, but not about the custom class stored in the vector. How to Use std:: find and std: find_if? First define a class: class Item{private: std::string m_ItemId; int m_Price; int m_

for the following part of the code, the VS2010 Windows platform prompts the array to cross (compile through, execute EXE prompts) but the codeblock is normal under deep Linux. The first form of /*vector ... 1.OutLineHand is a custom encapsulated contour class that contains data members and member functions. 2.filterContours is the vector 3.OutLineHand is a custom encapsulated contour clas

Original Figure 00 Final effect Diagram Figure 01 Just looking for the "monkey" material map, there are usually three ways to use the method of drawing: 1 The use of filter plug-ins, Knockout 2.0. The advantage of this plugin is that it is faster to pull down and less hair loss. 2) Channel pull graph method. 3) Pull out the drawing method. After thinking, we began the journey of experimentation. Scheme one: According t

Label: style blog HTTP color OS Io ar Div html When setting the CPU parameters during the learning process of the nioshi II, the Reset vector and exception vector settings are encountered. Shows the parameter setting screen. Reset vector -- Reset vectorException vector -- execution VectorFirst, it indicates that both

In practice, the vector series in c ++ -- Some vector exceptions Today, we will write some vector exceptions that can be captured. Out_of_rangeThe array is out of bounds. The vector automatically increases the capacity, but if the index exceeds the current size, an exception is thrown. # Include # Include

Hair removal is now more popular, who do not want their hair more, especially the armpit hair, legs and so on. Everyone hair removal is to use shaving, hair pulling, this is very troublesome, but also may hurt the skin, then how can sit to permanent

mentioned. This is the function interval. Description :A: Taking two-dimensional space as an example, the linear equation is changed to +c=0 ax+by+c=0. The usage vector w instead (A, b) is represented by the feature vector x, which is the formula.B: For the straight line we learned. By substituting the negative instance point (0,0), we can see that the calculated result +1 is inconsistent with

STD: Difference Between Reserve and resize of Vector1. Reserve: Allocate space, change capacity but not size2.Resize: Allocate space. Changing the capacity also changes the size. If you know the vector size, resize it as an array without allocating extra memory. ReserveIt is a container reserved space, but does not actually create element objects. Before creating an object, you cannot reference the elements in the container. Therefore, when add

There is a copy function in the STL algorithm. We can easily write this code:#include #include #include using namespace STD;int_tmain (intARGC, _tchar* argv[]) {Doubledarray[Ten]={1.0,1.1,1.2,1.3,1.4,1.5,1.6,1.7,1.8,1.9}; vectordouble>Vdouble (Ten); vectordouble>:: Iterator Outputiterator=vdouble.begin (); Copy (darray,darray+Ten, Outputiterator); while(Outputiterator!=vdouble.end ()) {coutreturn 0;}So you want to use copy to set the to vector, so you

As in the title, if I were to answer before, I would say, yes, in the multi-threaded environment to operate the vector, do not need to add synchronized.But I accidentally saw an article today, I found that my previous idea was wrong, the address of this article:http://zhangbq168.blog.163.com/blog/static/2373530520082332459511/I extract the key part:Vectors are slower than ArrayList because the vectors themselves are synchronized, and ArrayList is notT

Final effect First, to define the brush before starting to draw the hair, let's take 2-pixel hair as an example. 1, select the Brush tool, and then the Brush preset panel set the diameter of the brush is 2; 2, on the left side of the bread to choose the shape of the dynamic color, in the control of Xu my pen pressure, set the minimum diameter of 20; 3. Select the brush tip shape on the left

Final effect 1, a new size of 64 * 64 pixel document, Zoom to 300%, select Pencil tool, mode for dissolution, brush size of 1 pixels, the following figure. 2. Do some random points on the map. 3, select Filter > Blur > Gaussian blur, the value is: 0.4, the effect of the following figure. 4, select menu: Edit > Definition brush, name is hair. Next, select the Brush tool, the pattern is normal, set the spacing to

App design often uses some fuzzy effects or a glass effect, and iOS has now provided some fuzzy APIs that we can use for convenience. In the words of Apple after iOS7.0, many system interfaces have used the effect of the hair glass, increased the appearance of the interface, such as the following map of the notice center interface; But its iOS7.0 SDK does not provide the developer to achieve the glass effect of the API, so many people are through

Dynamically assigned vector pointer Vector If it is a dynamically allocated vector pointer, you can only use the array method (the above Code is red) when inserting elements into the vector. the push_back () function has an error. Why? Use the shared_ptr vector point
