读取DXF文件(2000,2002版本),包括了分层管理数据的思想,供大家参考(read DXF files (version 2000, 2002), including a hierarchical data management thinking, for your reference)

等值线函数.// As this code is ported from FORTRAN-77, please be very careful of the // various indices like ilb,iub,jlb and jub, remeber that C/C++ indices // starts from zero (0)(contour function.// As this code is ported from FORTRAN-77, please be very careful of the// various indices like ilb, iub, and* address, remember that the C/C indices// starts from zero (0))

该程序实现圆拟合，对学习圆拟合有一定帮助。(circle fit based on VC++)

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)

本程序可以在MFC中打开并显示一张图片，代码比较简单基础(Open and display a picture in MFC)

生成简单的绘图工具windows forms(generate simple drawing tools)

计算机图形学，mfc实现二维图形的基本几何变换，如平移、旋转、缩放、对称、错切变换(Computer graphics, mfc achieve the basic two-dimensional graphics geometric transformations, such as translation, rotation, scaling, symmetry, shear transformation)

绘图程序，可以自由绘制直线、矩形、圆、多边形，可以设置颜色和宽度，并且能够进行图元基本操作，如剪裁、缩放及填充功能。(Drawing program, free to draw lines, rectangles, circles, polygons, you can set the color and width, and can be primitive basic operations, such as cropping, scaling and filling functions.)

自由曲线图表、柱状图、饼图的实现与转换，基于一套简单的图形类库（源代码在内）。(free curve charts, column, pie and the realization of conversion, based on a simple set of graphics libraries (including source code).)

简单的图形学SRGP教学包运用实现。 A．实现一个下拉菜单软件包，其高层设计见2.2.6节、2.3.1节、2.3.3节中的代码段。软件包通过从输入文件读入字符串来初始化菜单条和菜单体。程序可以通过关闭菜单条使标题消失，也可以激活一个菜单（以各菜单标题在菜单条上的水平位置作为参数）来使菜单出现。 (Simple graphics SRGP realize the use of teaching packages. A. The realization of a drop-down menu package, and its high-level design, see section 2.2.6, section 2.3.1, section 2.3.3 of the code segment. Package from the input file is read into the string to initialize the menu and menu body. Procedures can be closed so that the title menu disappear, but also can activate a menu (in the menu heading in the menu bar on the horizontal position as a parameter) to make the menu appear.)
