In the process of developing county power grid dispatching automation system, the author encounters a problem to draw the primary wiring diagram of power system. As the power system wiring diagram is more complex, there are some special symbols, such as transformer symbols, switch symbols, and so on, with general programming methods to draw more difficult, therefore, the author uses C language to develop a hand-drawn power system wiring diagram of the keyboard

Author: Zhu Jincan Source: http://blog.csdn.net/clever101 Generally, in the drawing program, it is relatively simple to pick up the rectangle and the polygon. For example, in the crect and crgn classes of MFC, The ptinrect or ptinrgn function directly determines whether the vertex is in the graph. We pay attention to the way we pick up a line segment, because we generally use the width of a pixel to draw a

This is because when you drag the mouse, the line is displayed on the drawing board, but the line is not actually painted. so when should I buffer updates in

Snake-C-drawing program based on easyx graphics library (on): basic control function, easyx Since I learned the C language, I have always wanted to make a game. Today I am paying for it. The first time I wrote it, I wrote a lot of bugs. Today, I read several greedy snakes on the Internet and re-wrote them once. The effect is good. The following is a detailed construction process. Due to time constraints, t

In the previous sections, I demonstrated the creation of Windows using XCB, drawing in Windows, and capturing and handling events. In this article, I'll show you how to draw text in a window. Drawing text is of course inseparable from fonts, so I'll simply explore the core font system of X server. The usual, first on the code and run, the code is as follows:1#include 2#include 3#include string.h>4#include 5

After reading this article, you can implement the following interface: When I first saw RCP, I dreamed that one day I would be able to use it to develop a gorgeous 2D and 3D program, through the previous exploration, today can finally uncover the mystery of 2D drawing. In the bundle Resource manager's plug-in dependencies, we can see the Org.eclipse.swt.graphics package at a glance, and there is no dou

Change the DisplayStyle attribute to Text for each cell in the ToolScrip control. (3) program code. 1. When creating a menu event, the background of the form is cleared in white to implement the "File Cr
