How does PS define brush presets?
Steps:
1, open a picture in PS, use "Quick selection Tool", select petal; Ctrl+j ", will be plucked out petals;
2, choose "Edit"-"define brush preset"; pop-up window, take a name yourself;
3, in the painting of Larry's last one, you can find just the flowers we defined;
4, create a new document, set the foreground color, with a brush
First, IntroductionExe4j is a great tool to package the jar package as an EXE to run. He can integrate the JRE environment with the packaged EXE so that the packaged EXE application can run on a machine that does not have Java installed (provided the EXE is bundled with the JRE).Ii. Problems and SolutionsWhen using the EXE4J integrated JRE package EXE, when running the EXE application, the error message is found:Error Hint: Java Virtual machine discovers java_home corrupt, need to reload or
This article mainly describes the differences between JavaScript functions defined by function statements and expressions. Need friends can come to the reference, I hope to help you. Using JavaScript for many years, wrote countless functions, today but really understand the difference between the definitions of the two functions, is really a tragedy, write down this essay, to remind themselves to lay a good foundation, a lot of age, can not continue to be ignorant. nbsp; Usually we see the foll
Always in order to facilitate the implementation of a method, the way to define the variable at the top of the method, that this should and H file definition is the same, in fact, is defined in the M file variable is static, the class of multiple objects will be access to the same variable. The encapsulation of the slot OC is far from Java, and there is no concept of package, sometimes importing other people's code, their own code and others
Public functions in CodeIgniter cannot be appended and can be implemented through helper auxiliary functions.Create common_helper.php files, define the required public functions, and store them in the Application/helpers directory.Configure $autoload [' helper '] = Array (' common ') in application/config/autoload.php; Can.
Global variables can also be implemented with the help of helper functions. However, a more appropriate approach might be define
with static modifications can be defined in the header file and can be referenced by multiple source files, and there is no problem with compilation. Because a variable with a static modifier is mapped in memory to a static store, its variables persist until the program is run. And is a global variable.
2. A variable with a static modifier can be a global variable, and its value can be modified in the program.
3. A variable with a static modifier defined in a function or code block is scoped

Three ways for JavaScript to define classes (class)
Author: Ruan Yi Feng
In object-oriented programming, classes (Class) are templates of objects (object) that define properties and methods that are common to the same se
Requirements:1. Object has ID, host, port three properties2. Define tool create_id, randomly generate ID for each object at instantiation, guarantee ID unique3. Provide two kinds of instantiation mode, one: User incoming host and port mode two: Read host and port from configuration file to instantiate4. To customize the method for the object, save and Get_obj_by_id,save can automatically serialize the object to a file, the file path is db_path in the
, define a series of variables, animation mode Ah, the duration AH. Brushes, sizes, whatever. Public Sendbutton (context context, AttributeSet Attrs) {Super (context, attrs);TypedArray A = Context. Gettheme(). Obtainstyledattributes(Attrs, R. Styleable. Sendbutton,0,0);try {Mbuttoncolor = a. GetColor(R. Styleable. Sendbutton_buttoncolor, Color. White);Mbuttonside = A. Getdimensionpixelsize(R. Styleable. Sendbutton_buttonside, $);Mborderstrokewidth = A
Yesterday encountered a problem, pycharm can not run the Django program, see the error is: django.core.exceptions.ImproperlyConfigured:Requested setting CACHES, but Settings is not configured. You must either define the environment variable Django_settings_module or call Settings.configure () before accessing Setti Ngs. As a result, Baidu had no results for half a day, and finally found the answer on the Foreigner's website. The DJANGO project would h

It does not mean that it is correct or not, possible errors are detected and reported only when the expanded source program is compiled. For example:# Define PI 3.1415926In the program: Area = pI * r will be replaced with
1.1. # define variant, that is, # ifndef, can prevent repeated references to header files# Ifdef and # define combinations are generally used in header files to prevent repeated references of multiple files to the same header file.In actual use, even if your header file is not referenced by multiple files, it is best to add it to increase program readability, portability, robustness, and so on.Its usage is
Today, we have compiled some # define usage to share with you!1.

Define is a pre-processing command in C language. It is used for macro definition, which can improve the readability of the source code and provide convenience for programming.Pre-processing commands start with "#", for example, include commands # include and macro-defined commands # define. Usually put in front of the source file, which is called preprocessing.Preprocessing refers to the work done before c
A constant is an identifier (first name) of a simple value. As the name implies, the value cannot be changed during script execution (except for the so-called magic constants, they are not constants). Changshime is considered to be case sensitive. Usually, constant identifiers are always uppercase. You can use the Define () function to define constants. After PHP 5.3.0, you can use the Const keyword to
In PHP define () and const () can define constants, then the difference between define () and const exactly where, this many programmers do not understand, I would like to introduce to you some of this function usage ratio.
The difference between define () and const:

# Define usage
1.Simple define Definition
# Define maxtime1000
A simple maxtime is defined. It represents 1000. If you write
If (I
The compiler replaces maxtime with 1000 before processing this code.
This definition looks similar to a normal constant definition const, but it is also different, because the definition of defin
Const is used for the definition of class member constants. it cannot be modified after definition, and define is used to define global constants, so that we can access but cannot change it elsewhere, we will list the details below. note: define cannot be defined in... const is used for the definition of class member constants. it cannot be modified after definit
The difference between #define, const, typedef#define is not defining variables, it's just for text substitution.For example:#define PI 3.1415926float Angel;angel=30*pi/180;Then, when the program is compiled, the compiler will first "#define PI 3.1415926" after the "PI" in all the code is replaced by "3.1415926"and the
