•imgcodecs模块提供了图像文件的读写功能，用户使用简单的命令即可读写图像文件。图像处理操作imgproc模块提供了图像处理操作，如图

,cv2.COLOR_BGR2GRAY)发生了报错，报错内容为：[WARN:[email protected]]globalD:\a\opencv-python\opencv-python\opencv\modules\imgcodecs

目录加载图片保存图片加载图片openCv有一个名imread的简单函数，用于从文件中读取图像imread函数位于Imgcodecs类的同名包中。

publicstaticvoiddrawRect(){//分割图片并保存//1.加载由libname参数指定的系统库System.loadLibrary(Core.NATIVE_LIBRARY_NAME);//2.打开图片Matsrc=Imgcodecs.imread

表示每个通道灰度值所占的大小，大小即占几个位，是什么数据类型；图像类型：基于图像深度表述的信息，多了一个尾缀Cx，表示图像的通道数是x个；1.Mat对象Mat是OpenCV中用来存储图像信息的内存对象；当通过Imgcodecs.imread

解决方法：参考https://blog.csdn.net/qq_43521500/article/details/108751507成功解决

利用cv2读取图片发生如下错误：cv2.error:OpenCV(4.5.4)D:\a\opencv-python\opencv-python\opencv\modules\imgcodecs\src\

参考：http://blog.csdn.net/yhl_leo/article/details/51371936这个问题应该是opencv的问题具体来说，应该是opencv_imgcodecs链接的问题
