# 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
|
|
|

|
|
|
|
- A C++ compiler compliant with C++14 or above
|
|
- The JPEG library installed and configured.
|
|
|
|
### Execution requirements
|
|
|
