---------------
|
||||
Copies the selected image channel from a new-style C++ matrix to the old-style C array.
|
||||
|
||||
.. ocv:function:: void insertImageCOI(InputArray src, CvArr* dst, int coi=-1)
|
||||
|
||||
:param src: Source array with a single channel and the same size and depth as ``dst``.
|
||||
|
||||
:param dst: Destination array, it should be a pointer to ``CvMat`` or ``IplImage``.
|
||||
|
||||
:param coi: If the parameter is ``>=0`` , it specifies the channel to insert. If it is ``<0`` and ``dst`` is a pointer to ``IplImage`` with a valid COI set, the selected COI is extracted.
|
||||
|
||||
The function ``insertImageCOI`` is used to extract an image COI from a new-style C++ matrix and put the result to the old-style array.
|
||||
|
||||
The sample below illustrates how to use the function:
|
||||
::
|
||||
|
||||
Mat temp(240, 320, CV_8UC1, Scalar(255));
|
||||
IplImage* img = cvCreateImage(cvSize(320,240), IPL_DEPTH_8U, 3);
|
||||
insertImageCOI(temp, img, 1); //insert to the first channel
|
||||
cvNamedWindow("window",1);
|
||||
cvShowImage("window", img); //you should see green image, because channel number 1 is green (BGR)
|
||||
cvWaitKey(0);
|
||||
cvDestroyAllWindows();
|
||||
cvReleaseImage(&img);
|
||||
|
||||
To insert a channel to a new-style matrix, use
|
||||
:ocv:func:`merge` .

||||

||||
