抓图的原代码,很有趣

一个小小的画图工具，简单的功能，进似完美的界面。-A small drawing tools, a simple function, into the interface seems perfect.

在透明背景上绘制位图-in a transparent background bitmap drawing

采用rtp打包发送H264视频流例子，  采用VC6.0编写，是学习h264视频传输，打包发送的经典例子，里面有测试的264文件 和sdp文件， 可用VLC来测试 播放发送的视频，核心代码在以下几个文件h264toRtp.hRtpPack.hRtpPack.c请仔细阅读这几个文件。本人编译测试通过， 下载之后可直接编译运行

北京大学遥感所的研究生图像处理讲义高级遥感数字图像处理（硕士生课程）之图像数字化-Peking University

实现三维对象的平移，旋转变换，以及投影变换。 程序运行按键说明：a,s,d,w四键产生平移变换，x,X,y,Y,z,Z六键产生旋转变换，PageUp使镜头拉进，PageDown键使镜头推远。-3D object translation, rotation transformation, and the projection transformation. Running Press : a, s, d, w 4 keys generated translation transform, x, x, y, Y, z, Z six key rotation transform, Page dragged into the lens, the lens Prompt button pushed far.

显示PNG格式图像的汇编源代码，非常实用。-PNG format images showed a compilation of source code, very practical.

纯C语言开发的图标/图片按钮源代码，这个程序中使用了字体font, 绘制形状shape, 绘制边edge, 绘制颜色color, 使用刷子brush 和钢笔pen完成。 -Although Windows has a really cool GUI, sometimes the way standard buttons look quite does not meet our requirements. We may then choose buttons with a style called "owner-draw". The owner has to draw the button in every aspect (background, border, text, image) of every situation that requires drawing (click, enable, focus, etc.).It took me days to come up with something functional, Now here is some simple, reliable code: if it proves useful I will write something about owner-draw buttons with text (dealing with fonts, shapes, edges, colorrefs, brushes and pens).

几个小的圆的合成程序,互相交流一下,本人水平很低,初学者-Several small circular synthetic procedures, mutual exchange, I am a very low level of beginners

1,用经线和纬线画出一个三维球体,经线用不同的颜色表示,用帧交换技术实现球体的转动 2,在球体外部画1-3个小球,实现大球转动的同时,小球绕大球转及速度交互可调 3,考虑设计通用程序,实现小球的个数大小旋转的轨迹-one with warp and weft, paint a three-dimensional sphere, warp with different colors, Frame switching technology used to achieve the rotating ball two, ball in the external painting 1-3 small ball, and make major rotation of the ball, Small ball big balls turn around and adjustable speed interactive 3, the design of common procedures, the number of small balls the size of the rotating track

基于GVF的SNAKE一个实现的重要函数GVFC，网上搜得-An important function GVFC used to implement the snake (active contour) based on the GVF (gradient vector flow).
