Answer 3

I found something that is easier than mine:

#include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main( int argc, char** argv ) {
if( argc != 2) {
cout <<" Usage: display_image ImageToLoadAndDisplay" << endl; return -1;
}
Mat image; image = imread(argv[1], CV_LOAD_IMAGE_COLOR);

// Read the file if(! image.data )

// Check for invalid input

{ cout << "Could not open or find the image" << std::endl ; return -1;
}
namedWindow( "Display window", WINDOW_AUTOSIZE );

// Create a window for display.

imshow( "Display window", image );

// Show our image inside it.

waitKey(0);

// Wait for a keystroke in the

window return 0;
}

Answer 5

#include <Magick++.h>
#include <iostream>
using namespace std;
using namespace Magick;
int main(int argc,char **argv) {
// Construct the image object. Seperating image construction from the
// the read operation ensures that a failure to read the image file
// doesn't render the image object useless. Image image;
try {
// Read a file into image object image.read( "girl.jpeg" );
// Crop the image to specified size (width, height, xOffset, yOffset) image.crop( Geometry(100,100, 100, 100) );
// Write the image to a file image.write( "x.jpeg" );
}
catch( Exception &error_ ) { cout << "Caught exception: " << error_.what() << endl; return 1;
} return 0; }
