matter) a local variable that is used very frequently in a regular function call, you should elevate it to be a member of the object. That font is a good example. Only commonly used local variables frequent access is a good candidate, not the frequent call is not necessary. You should try to avoid duplicating the creation of the same object, using member variables instead of local variables.
The static property Brushes.black used in the previous example demonstrates another technique that avoi

Draw the approximate color block range, after that is the continuous refinement of the details, so that the color block more natural, it takes some time. But for the ultimate dream effect, I still enjoy it haha. After applying the soft steps to add some Gaussian blur layer, adjust the transparency, make the painting more natural. The final smear of the large color block is completed:
Draw more detailed lines: Use some more detailed

4th step
One of my favorite tricks is to use bright light points. Set the gradient radial (Gradient > Radial), and then set the slider to center, to get a large transparent edge. This way you can get a bright, clear central image. This is the way I do light dots. Now you can draw points of light in triangles or other simple graphs.
5th step
I use a cool palette gradient to draw ice-shaped petals. Draw an outline and leave the veins blank.

First, create art brushes
To make a stripe pattern, the first thing we need to think about is what tools are used to achieve it more quickly. Because such as stripes, dots, squares ... This kind of basic pattern has the common character that repeats a certain visual law
corner of the screen, you can find that the new version of the software to support the drawing board has been upgraded, we can use side-front to paint a large blur of color, you can also use the nib to draw a clear brush strokes.
Click the Brush preset button on the property bar to open the Brush drop-down list. We can find the brushes we need here. You can see Photoshop CS5 a few special drawing pens for us.

Asp.net| Interaction | Designed to make our objects serializable
To use a ASP.net object class in the application, we need to make another change to it. These classes need to be serializable to be able to pass data between the primary Web page and the Web page where the image is generated (detailed later). Serialization is the process of writing data from a class to a storage medium in a way that stores and/or passes data and deserializes later. Deserialization is the process of recreating an ob

VB mouse drawing Basic Data summary
In view of the first half of the program to write a mouse, this will be collected before the summary of the data, to those who used to search the same as me everywhere VB enthusiasts a little convenient, and welcome exchanges and corrections.
Here I try to write wordy and wordy some, I hope you do not blame me. Because we have a lot of information is too theoretical, practical or didactic people how to use, too weak. I wish I could be a little bit more clear.
[Copy question]:Given an array of n integers, and a sliding window of size k , slide the window from left to right in the array to find the median of each window in the array. (If the number of arrays is even, the N/2 number is returned after the window sorts the numbers.) )For an array [1,2,7,8,5] , sliding the size k = 3 window, returns[2,7,7]Initially, the array of Windows is this:[ | 1,2,7 | ,8,5], the median is returned 2 ;The window then continues to slide forward one time.[1, | 2,7,8 | ,5
Bridge Mode increases the understanding and design difficulty of the system. Since the aggregation association is established on the abstraction layer, developers are required to design and program the abstraction.The bridge mode requires correct identification of two independent dimensions in the system, so the scope of use has certain limitations.1.6 nature of the Bridge Mode

This program is similar to the Windows 7 desktop taskbar. When you double-click a shortcut on the desktop, a new subinterface is opened and a taskbar icon linked to this interface is created in the taskbar, when you move the cursor to the icon on the taskbar, the popup real-time image thumbnail is displayed. When you click the taskbar icon, the interface can be maximized or minimized, as shown in the following figure. The source code is downloaded from here.

variables
All reference types, including those local variables, are allocated to the stack. After the function exits, all local variables in the function will immediately become junk objects.. So we can draw a conclusion:
If a local variable of a reference type (value type does not matter) is used in a frequently called routine, it should be upgraded to a member variable. This helps reduce the GC burden and improve the program running efficiency.

1. Understand GDI +
GDI + is a library that provides an interface that allows programmers to write windows and web graphics applications that interact with graphic devices such as printers, monitors, and files. It is actually a class written by C ++ for our call. To use GDI + in a program, you need to add the corresponding namespace.
