OutputMode

enum OutputMode : Enum<OutputMode>

Output mode of binarization filter.

ParametricFilter

sealed class ParametricFilter : Parcelable

Base class for all parametric filters.

ScanbotBinarizationFilter

data class ScanbotBinarizationFilter(var outputMode: OutputMode = OutputMode.BINARY) : ParametricFilter, Parcelable
