目录
效果
直接输出：
Mat [ 3*2*CV_8UC3, IsContinuous=True, IsSubmatrix=False, Ptr=0x1eb73ef9140, Data=0x1eb73ef91c0 ]
格式化输出：默认风格
[ 91, 2, 79, 179, 52, 205;
236, 8, 181, 239, 26, 248;
207, 218, 45, 183, 158, 101]
格式化输出：Python风格
[[[ 91, 2, 79], [179, 52, 205]],
[[236, 8, 181], [239, 26, 248]],
[[207, 218, 45], [183, 158, 101]]]
格式化输出：CSV风格
91, 2, 79, 179, 52, 205
236, 8, 181, 239, 26, 248
207, 218, 45, 183, 158, 101
格式化输出：NumPy风格
array([[[ 91, 2, 79], [179, 52, 205]],
[[236, 8, 181], [239, 26, 248]],
[[207, 218, 45], [183, 158, 101]]], dtype='uint8')
格式化输出：c风格
{ 91, 2, 79, 179, 52, 205,
236, 8, 181, 239, 26, 248,
207, 218, 45, 183, 158, 101}
格式化输出一行：Python风格
[[[236, 8, 181], [239, 26, 248]]]
格式化输出一列：Python风格
[[179, 52, 205],
[239, 26, 248],
[183, 158, 101]]
格式化输出ROI 矩形：Python风格
[[[ 91, 2, 79], [179, 52, 205]],
[[236, 8, 181], [239, 26, 248]]]
格式化输出ROI Range：Python风格
[[[ 91, 2, 79], [179, 52, 205]],
[[236, 8, 181], [239, 26, 248]]]
