图像加密，循环变换后恢复

一款比较经典的vc绘图，图像处理程序源码，功能齐全。是学习vc图像编程的好资料-classic vc graphics, image processing procedures source, complete functions. Vc study is a good image information program

灰度图的描绘在VC语言中-grayscale image in VC Language

字符识别程序 mydate.dat为字库 先点击file, 点open，读入字库 学习时字库自动保存 已有键盘字符，字母，数字 和简单汉字 如要识别复杂汉字，请先用学习功能 向原作者致敬!-Character recognition process for the font mydate.dat click file, point open, read font study has been automatically saved font keyboard characters, letters, numbers and simple to identify the complexity of characters such as Chinese characters, please use learning function to the original author salute!

图像处理基础算法，其中包括：中值滤波、直方图均衡化、阀值变换、梯度锐化、高斯平滑、灰度均衡、巴普拉斯锐化、对比度拉伸、傅里叶变换、均值滤波、图像旋转、图像细化、图像平移、hough变换等 

方块编码,在readme.txt里有详细的使用说明-block coding, the readme.txt are detailed usage

OpenCV 4下的图像任意角度的旋转 //待旋转的图像Img_old //返回的旋转后图像类型 IplImage* Img_tmp. //旋转的角度,单位度. //三种不同的方法.其中方法二没有完全测试,方法一可以满足大部分需要-OpenCV four images of arbitrary rotation angle// Image Rotation question Img_old// to return to the rotation after the image type IplImage* Img_tmp.// Rotation angle, unit degrees.// Three different ways. Two methods which do not fully test one way to meet the needs of the majority

二维图形渲染引擎，可以同时对二维的BITMAP和矢量进行操作（通过一序列的API函数，基于AGG）-Graphin is a 2D graphics rendering library with human readable yet simple external interface (API). It is based on AGG- high fidelity 2D graphics engine and uses libpng/zlib, jpeglib and libtiff(?). External (plain C) API is as close as possible to Graphics and/or to Canvas.

计算机图形学中的一种算法----多彩变换曲线算法。对于本学科的初学者很有帮助。-computer graphics algorithms-a colorful transformation curve algorithm. The subjects for beginners helpful.

图形的常用变换  镜像  轮廓 膨胀  腐蚀等处理  image.initialize(); image.erzhi(); image.mirrow(); image.change();     image.smooth(); image.canny(); image.outline();     image.minus(); image.dilate(); image.erode();
