# Histogram computation
|
||
|
|
|
||
|
|
Histogram computation capabilities in GIL are demonstrated by the program `tutorial_histogram`, compiled from the sources `example/tutorial_histogram.cpp`.
|
||
|
|
|
||
|
|
## Synopsis
|
||
|
|
|
||
|
|
`tutorial_histogram`
|
||
|
|
|
||
|
|
The program expects to find an image in the JPEG format in the current directory named `input.jpg`, and produces a text file named `out-histogram.txt`, in the current direction, where the histogram has been calculated..
|
||
|
|
|
||
|
|
The program doesn't take any command line arguments.
