The brightness parameter increases or decreases the amount of perceived light an image radiates or reflects.

Syntax

brightness={value}

value may be any number between -100 and 100.

Notes

  1. The default value is 0. This leaves the image unchanged.
  2. A value of 100 will result in a fully white image.
  3. A value of -100 will result in a fully black image.
