一个很简单的VC++实现的在窗口中写字的程序 供MFC初学者参考-a very simple VC in the window and write procedures for beginners reference MFC

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).

用DELPHI 编写的Gamma曲线,可以参考一下.-prepared with the DELPHI Gamma curve for reference.

想做一些图像匹配，所以最近学习使用openCV，并做了一些试验。利用 OpenCV 实现了根据颜色直方图和形状进行图像匹配的功能，能够对摄像头的实时图像和本地照片进行匹配。Demo仅能在真机中测试，因为需要用到摄像头。作者：jimple_金鸿

IPM模块作为功率集成电路产品, 它使用表面贴装技术将三相桥臂的六个IGBT及其驱动电路、保护电路集成在一个模块内, 除了具有驱动功能外, 还具有很多保护功能，与传统分立IGBT或模块相比, 其具有体积小、功能多、可靠性高、价格便宜等优点。-IPM as the power IC products, which use surface mount technology arm of the three-phase bridge and six IGBT driver circuit protection circuitry integrated into a module, in addition to driving functions, but also a lot of protection, and the traditional separation or IGBT module compared to its small size , functional, high reliability, low price advantages.

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
