Parameters

reductionMode

Image conversion mode to be applied during the conversion of the image. Possible values are: AUTO, SET, GLOBAL.

brightness

Brightness of the image (range is 0 to 100, where 0 means the darkest and 100 means the lightest resulting image). This parameter has an effect only if the conversion parameter is set to AUTO.

threshold

Threshold value to be set. Its range should be between 0 and 255. This parameter has an effect only if the Conversion parameter is set to SET.
