学习opencv过程中,使用IPLImage结构,调用数据时定位数据区别width和widthStep: 1.width表示图像的像素个数,也就是图像的水平长度 2.widthStep是保存的数组长度,
100,没问题,又正确了,再变回动态大小区域,问题又来了…按理说这个大小对我的代码应该没影响…不经意的看了一下每次切的大小,发现切偶数大小rect时时正确的,奇数大小的rect则显示错误,忽然想到貌似IplImage...分别取宽度为奇偶的图片,读这个widthStep参数,果然,偶数的话跟上面计算一样,奇数就会多出一些,那就不难理解为什么会产生错位了.一般对于奇数的width会填充一个RGB,也就是3bytes.那么现在要对IplImage...图像数据进行操作,就要按行取(IplImage的imageData是按照BGRBGRBGR按行存储的),然后每一行顺加一个widthStep了,不能傻傻的按照width x height的二维数组来计算了
