大家要把握机会阿 非常难得的代码阿 赶快下载吧-The code is wonderful! Download now, come on!!

一个可以跟商业代码媲美的源代码，基本包含了cad的基本功能实现，用vc开发的，感兴趣的可以研究下，学习下！-With a commercial code comparable to the source code contains the basic cad realize the basic functions, using vc developed interest can be studied, the study under!

数字水印处理系统主要由水印嵌入和水印检测两个过程。（1）水印嵌入过程为：数字水印（X）、原图像（I）和密钥/公钥（K）通过数字水印嵌入算法形成嵌入水印后的图像（I*）。 （2）水印检测过程为：数字水印（X）、水印图像（I*）和密钥/公钥（K）通过数字水印检测算法检测出数字水印或有无水印。该程序调试已通过！-Digital watermarking system mainly consists of watermark embedding and watermark detection of the two processes. (1) The watermark embedding process as follows: Digital watermarking (X), the original image (I) and key/public key (K) by digital watermark embedding algorithm to form watermarked image (I*). (2) The watermark detection process is as follows: Digital watermarking (X), the watermark image (I*) and key/public key (K) by digital watermark detection algorithm to detect whether the digital watermark or watermark. The program debugging has passed!

绘制等值线和等值面，并生成SHP格式的矢量文件-contour mapping and surface contour, and generating SHP vector document format

C++Builder实现图象增强，将原先对比度低的图象变的层次分明，效果很好。-C Builder image enhancement, the original low-contrast images change structured, with good results.

51上用19264液晶的源码,包括画线和汉字.初学者很有帮助噢-51 with 19,264 LCD on the source, including line drawing and Chinese characters. Beginners helpful Oh

WGF (windows 图形基金会) 为windows下的gdi和gdiplus双缓冲绘图框架。框架在VC6.0下使用C + + 语言开发而成并以可扩展的MFC动态链接库形式提供，适用于windows操作系统。WGF为完全开源的免费产品，可以用于任何商业的和非商业的用途。WGF设计的目的是对windows下的gdi和gdiplus双缓冲绘图进行封装和优化。WGF封装了使用gdi和gdiplus进行双缓冲绘图的实现细节，使用框架进行双缓冲绘图时感觉就像是在窗口上绘图一样。同时，WGF通过将绘图内容划分为静态场景和动态场景以及通过采用gdi和gdiplus混合绘图的方式对windows下的gdi和gdiplus绘图进行了优化。
