A script for generating (random) noise background images.
🌐 Homepage: php-noise.com - 
GitHub Repository
php-gd is required for this script to work.
You can install it with:
sudo apt install php-gd
Create a directory mkdir images and chmod 0777 ./images/ it.
You can either use this script via CLI or in the Browser.
The Browser script has several high-caps to prevent too big values.
$php noise.php --help and $php noise.php -h, and ./noise.php?help in the browser will show all possible parameters.
All parameters are optional. A script call in the browser requires passing parameters via GET.
-h, --help
Shows this help text and exits the script.
--hex <value>
Color HEX Code
Possible values: #000000-#FFFFFF
The hash (#) must not be provided. If the parameter is provided, the -r -g -b parameters will be ignored.
If the Hex-Code is invalid, a random color will be generated.
-r <value>, -g <value>, -b <value>
Red, green, blue
Possible values: 0-255
If one of the parameters is invalid or not provided, it will be generated randomly.
If the --hex parameter is provided, all three of these parameters will be ignored.
