Word blending is very powerful, and we often use Microsoft Word to compile math lesson plans, test papers, print documents, But drawing is often a headache. In fact, the cartographic function in Word is quite powerful, there are many tricks. If the use of the process of careful experience of repeated groping, can greatly improve the efficiency of the production of mathematical graphics, drawing a very beaut

There is a need for a system that contains web-side background and WinForm drawing client programs, where users need to be able to start the drawing client on the Web side, and do not need to log on again (because they are already logged on to the web side). So on IE Web side, how to start WinForm to do the drawing cl

The GDI drawing consists of the following sections: 1. Drawing of points and lines 2. Draw the Fill area Point SetPixel () and GetPixel () are set pixel points and get pixel points. In theory, all graphics device drivers only need to implement the SetPixel () function and the GetPixel () function, and everything else can be handled using higher-level programs in

1. First of all, we hit the opening menu of the Win7 flagship computer, after that, we click on all the programs in the Start menu-attachment, in the attachment, we can see the Win7 flagship computer with the drawing function, we only need to left-click the drawing can be entered into this function. 2. In addition, we can also directly open the Win7 flagship c

Drawing in VC is not flashing. You can use memory to draw a picture and copy the picture to the device. However, the result is that the image display speed is improved, but it is still very flashing. How to Avoid flashing the display image, how to Improve the display efficiency, and most people think that the MFC plot function is very inefficient, always I want to seek other solutions. The drawing efficienc

The Linux configuration file has been developing for a long time. Here I will share my personal understanding. Next I will talk about the Linux configuration file. There are three common Linux GUI programs: GTK1, GTK2, and QT. Programs Based on these three graphics libraries have different requirements for beautification. Common font drawing schemes in XFree86 in

For the students just contact QUARTZ2D, first understand the concept of the context, and then from the most basic line to experience the quartz2d of the drawing stepsIntroduction QUART2D: Apple's official two-dimensional (planar) drawing engine, while supporting both iOS and MacOS systems, its API is pure C language, it can draw graphics, draw text, draw pictures, custom UI controlsIn iOS development, quart

Double Buffer drawingAuthor: Unknown category: VC/VC. Net Date: 20:51:47There are many questions about how to avoid flickering and how to improve the display efficiency. Most people think that the efficiency of the MFC plot function is very low, and they always want to seek other solutions.The drawing efficiency of MFC is indeed not high, but it is not bad, and its drawing function is very simple to use, as

what is the drawing context (Rendering contexts)Beginner OpenGL, open Red Book, will tell you that OpenGL is a state machine, OpenGL uses the client-server model, then felt good abstraction, until later understand the drawing context to connect these. We can assume that each hardware GPU is a server, each drawing context corresponds to a client of the request, a

This is my recent "Computer graphics" course practical programming class introduction of the relevant knowledge, mainly want to use MFC C + + drawing, let students realize the graphics related to the programming and simple graphic drawing, at the same time very admire the students imagination, they do really good. I hope this basic article will be of some help to you. In particular, students with this cours

BodyThe headline is a bit scary, but drawRect the evaluation is not too much. In the development of weekdays, the random coverage drawRect method, a little careless will make your program memory burst. Let's look at an example below.Do an artboard function, but suffer from memory problems have not been solved. The artboard function is simple, which is to record the track of your finger touch and then draw it on the screen. Let's take a look at the following:We see the state of the left memory de

First, quartz2d simple introductionThe drawing framework commonly used in iOS is quartz2d,quartz2d is part of the core Graphics framework, and all of the Uikit components we use in our daily development are made up of core Graphics that are drawnGeneral steps for quartz2d drawing in iOS: Get Drawing context Create and set a path Add a path into t
