Potrace是一个位图图片的优化工具，它可以使其成为平滑，可自由缩放的图片。它输入的格式可以是PBM, PGM, PPM, 和 BMP 格式，默认的输出格式是EPS文件，它可以用于将公司的徽标和文件的扫描图片的锯齿消除，以任何分辨率显示出来。它的输出格式有： EPS, PostScript, PDF, SVG , Xfig, Gimppath, 和PGM . -Potrace is a bitmap image optimization tools, which can make it smooth, free to zoom the pictures. Its format can be imported is PBM, PGM, PPM, and BMP formats, the default output format EPS files, it can be used for a company"s logo and documents scanned images to eliminate the jagged, any resolution to be displayed. Its output formats : EPS, PostScript, PDF, SVG, XFIG, Gimppath and PGM.

用VC++实现的图像读取的基本算法，可读取DIB文件-Using VC++ to achieve the image to read the basic algorithm, DIB files can be read

一个进行图章识别的C＋＋类，主要采用图章图像的矩特征进行图章比对，涉及到图像特征提取与匹配。-identification seal for a C++ class, mainly stamp image features seal moment than right, relate to feature extraction and image matching.

用java读DXF文件(ReadWorldmap.java)源码-with DXF files (ReadWorldmap.java) FO

关于图形中曲线曲面编程(源程序)-on graphics programming curves and surfaces (source)

数字图像处理中关于色彩空间变换的实现，色彩空间包括：YUV，YCbCr,Iab,RGB,XYZ等等。-Digital Image Processing for color space conversion in the color space include : YUV, YCbCr, Iab, RGB, XYZ and so on.

椭球体的碰撞检测。在以人形为主的场景内椭球体的碰撞精度比球体、AABB、OBB都要高，同时速度也很快-Ellipsoid collision detection. Human-oriented in the scene of the collision within the ellipsoid accuracy than the sphere, AABB, OBB higher speed quickly at the same time

功能:连接多义线,将选定标注改为当前标注形式,给标注文本加括号,恢复所有图层先前状态-Features: Connect polyline will be replaced by the current marking of selected forms of tagging, to mark the text in brackets added to restore the previous state of all layers

用VB6写的一个波形绘制软件，类似windows 任务管理器界面，只是绘制一个框架，实时波形须在控件的Display()方法中加入代码-Using VB6 to write a waveform drawing software, windows task manager like interface, but a framework for mapping, real-time waveform to be in control of the Display () method to add code
