二维图形的几何转换，首先通过屏幕上任意四点绘制通过四点的曲线，再通过平移，旋转缩放等实现一些简单算法-2D geometry conversion, first through the screen drawing arbitrary 4:00 through 4:00 curve, and through translation, rotation scaling algorithm to achieve some simple

提供完整的 2D 图形功能，这包括抽象的 BMP 可绘制对象，几何图元的绘制功能，颜色管理功能，调色板管理功能，位块传送功能，BMP 图片文件功能，点阵字体功能和 Animate 动画对象功能

该程序在视图动态绘制多种2D图形，如柱状图，饼图，线图等。内含源代码及示例程序-Dynamic view of the program draw a variety of 2D graphics, such as histograms, pie charts, line diagrams. Contains the source code and sample programs

二三维混编程序，可以在三维窗口里面对二维图形和三维图形一起显示,降低三维绘制难度。-2D and 3D mixed program, it can display 2D and 3D graphics together in a three-dimensional window inside.
