Constructors

AutoLevelProcessor(int, bool, int, bool)

Initializes a new instance of the AutoLevelProcessor class. It uses the exact minimum and maximum values found in the luminance channel, as the BlackPoint and WhitePoint to linearly stretch the colors (and histogram) of the image.

public AutoLevelProcessor(int luminanceLevels, bool clipHistogram, int clipLimit, bool syncChannels)

Parameters

luminanceLevels int

The number of different luminance levels. Typical values are 256 for 8-bit grayscale images or 65536 for 16-bit grayscale images.

clipHistogram bool

Indicating whether to clip the histogram bins at a specific value.

clipLimit int

The histogram clip limit. Histogram bins which exceed this limit, will be capped at this value.

syncChannels bool

Whether to apply a synchronized luminance value to each color channel.

Properties

SyncChannels

Gets a value indicating whether to apply a synchronized luminance value to each color channel.

public bool SyncChannels { get; }

Property Value

bool
