Research on GDI + and graphics programming, and gdi graphics programming
Basic concepts of GDI +
Common objects of GDI +, including creating and using Graphics, Font, Brush, Pen, and other objects
Drawing common images
Color Structure, Point structure, and Rectangle Structure
1. Concept of
Graphical device interface (GDI)
The graphical device interface (GDI) is an executable program that accepts drawing requests from Windows applications (expressed as a GDI function call) and sends them to the corresponding device driver, complete hardware-specific output, such as printer output and screen output.GDI is
This is a common problem at work. The printer purchased by the company does not have the network printing function, but wants to allow all staff in the office to share the printer. Setting the printer to share can solve this problem well. Next, let the editor teach you how to set up printer sharing.Windows
Of course, I would like to use GDI + to completely replace GDI, and then only need to go from GDI objects to GDI + objects. But there are a few projects, but also new technology features, but also want to quickly develop, and will not discard the old version of the existing features. No way, can only sewing, ka bang 碙
A About the basic concepts of GDIWhat is GDI The essence of Windows drawing is to take advantage of the graphics device interface provided by Windows GDI(Graphics devicesInterface ) to draw the graphic on the display.In the WINDOWS operating system, GDI functions are defined in the dynamic-link library C:\WINDOWS\system32\gdi32.dll(
D2D engine and GDI \ GDI + rendering Effect Comparison, d2dgdi
This example compares D2D and GDI in drawing text and lines, and D2D and GDI + in drawing pictures.
D2D is developed based on COM components, and the former CoInitialize (NULL) is required. In addition, do not forget to initialize GdiplusStartup () of
application then calls the StartDoc function to start a new document, which is processed by the GDI module, and the GDI module calls the control function that was just called into the in-memory printer device driver, telling the device driver to prepare for printing. Then call the StartPage function to start a new page, end this page with the EndPage function, a

I saw the drawing software I made yesterday. It has the effect of layers, so I will configure the GDI + Environment myself. I will paste the common operations I learned about GDI tomorrow.

Enterprises cannot do without networks or computers and printers. Generally, a company only has one or two printers. It is impossible for every computer to have a printer installed. This will make printing inconvenient, if you want to print a document without a
Demo of Sorting Algorithm with plug-in
This section uses an example to describe the application of GDI + in MFC. This algorithm demo is actually the beginning of my algorithm series. Since csdn does not have a tree-like directory structure, I have to use a linked list, isn't it? Well, I will not talk much about it. I will start my article today.
(1) Function Description
Our initial functions are as follows:

client's video card completes the drawing. GDI can also accomplish other tasks. Most computers have multiple display devices---monitors, printers. GDI successfully makes the printer that the application uses look the same as the screen. If you want to print something instead of showing them, simply tell the system that the output device is a
I remember there are multiple methods, but some of my current materials have not been restored. Below is a netizen's.
I remember that I used it because the string painting of gdi + cannot be restricted in the region, while gdi is acceptable. This is really strange.

When a recent project draws a large amount of collected data, it may cause a program crash due to memory leakage. After repeated speculation, it may be due to the release of the GDI object. Now we can find the following online experience, it should be helpfulUse of GDI objects and prevent resource leakageFor programming on the Windows series, GDI is a very import

How does LAN Printer sharing work? How do I set up printer sharing?
To achieve two printers or multiple printer sharing, first of all to understand how to set up and share a local area network printer computer printer, after the need to solve the LAN on the other computers
GDI + is a sub-system in windows XP and windows Server 2003. It is mainly used to process system message rendering. GDI + is an extension of GDI. It inherits a bit of GDI and makes improvements based on it, including adding some graphic functions that cannot be drawn by GDI,

For programming on the Windows series, GDI is a very important technical point. Many programs run abnormally many times, except for the well-known memory leakage, the leakage of GDI resources is also a direct cause. today, I will share some of my experiences in programming with you.1. For the created GDI object, you must use deleteobject to release it. The releas
First, verify that the printer is properly installed
Local printers are not available, first from the easy and difficult order to determine. Verify that the printer is installed correctly by the machine.Let's start with a brief WIN7 the installation steps for the printer.Open the device and printer options below the Start menu;
After opening the screen;
