Gradients calculations

Gradients calculations capabilities in GIL are demonstrated by the program x_gradient, compiled from the sources example/x_gradient.cpp.

Synopsis

x_gradient

The program expects to find an image in the JPEG format in the current directory named input.jpg, and produces an image in JPEG format in the current directory in return, named out-x_gradient.jpg, where the gradients have been captured.

The program doesn't take any command line arguments.

Specific requirements

Build requirements

  • A C++ compiler compliant with C++14 or above
  • The JPEG library installed and configured.

Execution requirements

x_gradient expects to find an image in the JPEG format in the current directory.
