---------------------------------------------------------------------------------------------------------------
Description::
This is a C++ program to show the use of transpose funtion which is inbuilt in the opencv library. Transpose function takes 2 parametres. FIrst is mat object for input image and second is mat object of another desired output transposed image.

Program::
#include <opencv2/opencv.hpp>
using namespace cv;
int main( int argc, char** argv )
{
char* ImageFile = argv[1]; //image file
Mat image;
image = imread( imageName, IMREAD_COLOR ); //reading file
if( argc != 2 || !image.data )
{
printf( " No image data \n " );
return -1;
}
Mat transposed_image; //Mat object for storing data
transpose(image,transposed_image); //transposing given input image
imwrite( "/home/crmgogo/Pictures/transposed_image.jpg", transposed_image ); //Saving images
namedWindow( imageName, WINDOW_NORMAL );
namedWindow( "transposed_image", WINDOW_NORMAL );
imshow( imageName, image ); //show windows
imshow( "transposed_image", transposed_image );
waitKey(0);
return 0;
}
