The Contrast/Brightness Block is used for modifying an JPEG or PNG images contrast or brightness. A value of 100 results in an unmodified property. A lower value will reduce the contrast/brightness. A higher value will result in more contrast/a brighter image.
Use cases
- Modifying the contrast/brightness of user generated (e.g. signature) or downloaded (probably dynamically generated) images.
