GDI + is a commonly used graphical and image tool in C ++ ,. many languages of net even use GDI + to draw their interfaces.In the winsows system, almost all APIs are directly targeted at the C language. Except for C/C ++, these APIs must be transplanted in other languages, the gdiplus header file provided by Microsoft, from the type definition to the method interface, is all written for C ++, which makes th

Use GDI + to save your drawing data. Save your drawing as a BMP image. // Define the BMP image object Bitmap BMP (300,300); // the size of the image to be created can be ---------------------- 1 // Define the Drawing Object Graphics g ( BMP); // all the drawings are completed by G -------------------------------------------- 2 // Use g to draw an image G. Draw (...); // --------------------------------------------------------------------------------

. Here is the point of this article: use GDI + to achieve image rotation processing. I want to understand GDI + is not a lot of people, because it is a new thing in Windows. For details about this, refer to the MSDN articles. GDI + is an enhanced version of the GDI graphics library, which can be used by C + +. It is b

Windows GDI beginner application (vc sdk) I haven't posted a post for a long time. Today, my hand is itchy.The drawing functions of GDI are basically stateful, and all functions require an HDC handle.There are several ways to obtain this HDC: beginpaint, getwindowdc, and getdc. They only need one hwnd parameter.Remember to call endpaint to clean up after beginpaint is called. Call getwindowdc and getdc to

limit.And look at some of the coordinate systems in Windows1. screen coordinatesThe screen coordinates describe a coordinate system for a physical device (display, printer, and so on), where the coordinate origin is in the upper-left corner of the screen, the x-axis is positive on the right, and the y-axis is positive. The unit of measure is the voxel. The origin, axis direction, and measurement units are not able to be changed.2, equipment coordinat

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 relea

If you want to design a unique ICO image of your own, and then make it an icon like "My Computer" and "Recycle Bin", what do you do? Only some special drawing tools are used. Because the paint program for Windows cannot create an ICO file. So I used. NET and GDI + to write a drawing tool like this. Although there are many articles that introduce GDI + technology, but are just pure

How is the MAC system WiFi printer connected? Many users who just use Macs may not know much about Mac, and many people are asking, how does a WiFi printer connect to a Mac? How to use the WiFi printer? How to set up to quickly connect to the WiFi printer, small written this article does not cover all Wi-Fi Various pos

Daily life we are often exposed to the printer, especially now the network office of the Young, often in the office work will come into contact with the printer! The printer, is plainly: through a device, the most common to A4 paper as media, the computer text documents or pictures by mechanical transfer on the paper, Make abstract things concrete! Since it is a

Load and decompress the GDI + development kit; 2. Set the include lib directory correctly; 3. Add stdafx. h: # Ifndef ulong_ptr # Define ulong_ptr unsigned long * # Endif # Include 4.ProgramAdd the file gdiplus. h and the additional class library gdiplus. lib to the GDI +. Generally, gdiplus. h contains files added to the stdafx. h file of the application: # Pragma comment (Lib, "gdiplus

I. OverviewThe Application of GDI + makes it easier to program graphic images on a plane. This article uses a dialog box-based clock program as an example to call * In vc6.0 *. PNG Image implements a translucent gradient window. The program implements two clock display modes: pointer and digital. The window implements a translucent gradient window, the window is dragged without moving a rectangular box, And the taskbar form button is hidden.As follows

GDI + has been upgraded and optimized based on the original GDI, such as line smoothing, color transparency, and graphic Transformation (translation, scaling, and rotation ), more image formats and other technologies have been greatly improved. using GDI + can easily draw and optimize various images. GDI + is a. Net co

The Application of GDI + in the Delphi Program-there are many ways to adjust the brightness of an image, the most common method is to increase or decrease a certain value at the same time for the R, G, and B components of the image pixel to adjust the brightness. Here I use the Scan Line of the GDI + image for processing. The core processing adopts two identical processes, one is the PASCAL process, and the

Author: famous sci-tech Bureau Source: site original hits: updated on: Whether in the office or in the home, it is unlikely that every computer will be equipped with a printer. At this time, the sharing of printing will have to be faced. Print Sharing can be said to be the most common peripheral Sharing Solution in the LAN environment, because the implementation is very simple, users do not need to have too much computer knowledge to do it. Now let's

GDI + is a function library of Windows, from Windows\system32\gdiplus.dll, which contains 610 functions. Use in Delphi need to download and install GDI + for Delphi First (this is used for 2006, 2007 Win32 version). Provide a new download: Http://files.cnblogs.com/del/GDIplusNew.rar; The above Delphi 2009 under the problem, this version slightly higher a little. After writing the first 31

"Printing failure" is mostly caused by improper printer use, installation, and setup. Virus, printer damage, and printer port failure may also cause printer printing failure. If the printer cannot be printed in Windows 9x, follow these steps: 1. First, check whether the

Cause: Because the Internet IP address is limited, a vro is added to bind an Internet IP address and a MAC address to a vro. Then, the machines under the vro can access the Internet. But we cannot connect to the printer of our team lead, because we are in Segment 2 (192.168.2.1) and the team lead is in Segment 1 (192.168.1.1 ). The company also has a large printer (with its own Nic, which can be configured

What is DIRECT2DWord, a 2D graphics API on the Windows 7 platform, provides high-performance, high-quality 2D rendering. Most people may be unfamiliar with direct2d, so that when I mentioned the word in the forum, someone actually said you were wrong? Maybe everyone is more familiar with Direct3D, because D3D is already the mainstream application of the current game field. In the past, the 3D World was OpenGL and DirectX, but because of the lag in OpenGL development and the lack of a powerful ba

The screen and editing functions were added to the previous paragraph in an IM communication tool similar to QQ. However, during the test, it was found that after dozens of consecutive times, the system would display a white screen, at first, I thought it was related to the frequent flash white in Windows 7. When the screen was captured to the flash, the white screen was generated. Later I found that the GDI memory was insufficient and the failure to
