DrawLine

C#仿绘图板制作的绘图程序源码,可以修改大小，旋转。可以放图片(Paint Code Develope By C#，can put picture )

可以实现基本的绘图功能，画直线，矩形，圆椭圆。图形学作业(Can achieve the basic drawing functions and draw a straight line, rectangle, circle, ellipse. Graphics jobs)

ObjectARX开发，配电网，网络绘制，潮流计算，可靠性分析等(ObjectARX development, distribution network, network rendering, flow calculation, reliability analysis, etc.)

绘画板~ C#小程序~ (Drawing board ~ C# Applet ~)

MFC 画出简单的坐标 并通过按钮产生随机点坐标（横坐标逐渐增大纵坐标随机）存入文件中 另一按钮实现读出数据并将点连成折线(MFC drawing simple coordinate and through the button generates random point coordinates (abscissa increases ordinate random) into a file and another button to achieve read data points connected into line)

该VB程序可以将外部输入的数据以图形的方式画出，提供了一个参考,并有图形刷新功能，很详细的介绍了VB的画图功能(The VB program can draw the external input of data in graphical form, to provide a reference, and graphics refresh function, a very detailed description of the VB drawing functions )

draw用法。新手必看，通俗易懂，请结合工具书(draw Xinshoubikan usage, easy to understand)

使用MFC创建单文档程序，在界面上画圆，单击可使圆放大、变色(MFC SDI DRAW CIRCLE, CLICK TO INFLATE THE CIRCLE AND CHANGE ITS COLOR)

本文以电场的三大定理、连续超张弛迭代算法、拉格朗日插值算法等原理知识作为理论基础，以 C 语言为编程工具，将由根据以上物理和数学原理所推导出来的模型转化为可以计算像管内电势的 CAD 程序软件。所编写的程序可以在给定像管参数和电极电位的情况下，计算圆柱形像管内任意一点的电位大小，并绘制出像管内的等势线；拉格朗日插值得到对称轴上任一点的电位值。 (In this paper, we base on the three theorems of the electric field, continuous ultra-relaxation iterative algorithm, and Lagrange interpolation algorithm. We use the C language as a programming tools, and transform the model derived above into a CAD software to calculate the electric potential in the image tube. In case the image tube parameters and electrode potential are known, the program written can get the potential of every point in the image tube, and plot equipotential lines inside the image tube. It can also get the potential of every point on the axis of symmetry by Lagrange interpolation. )

对图片进行网格划分，以及绘图获得区域，最终获得灰度矩阵(Mesh the image, and draw the region to obtain the gray scale matrix)
