ColorAdjustmentProvider.AutoLevels Method (Double, HistogramMode)

Automatically applies levels adjustment using provided threshold level and histogram mode.

Namespace: Aurigma.GraphicsMill
Assembly: Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

Syntax

Visual Basic
Public Sub AutoLevels ( _
	threshold As Double, _
	histogramMode As HistogramMode _
)
C#
public void AutoLevels(
	double threshold,
	HistogramMode histogramMode
)

Parameters

threshold

Type: System.Double

Threshold level of the automatic level correction algorithm (sensitivity).

The threshold value is used to define a percent of pixels on edges of the tonal range to discard. Threshold = 1 is 100% of pixels. To get more or less realistic result, use a value less than 1% (0.01). For example:

  • If you want to get a result similar to Photoshop® 7, use 0.5% (0.005).
  • If you want a result similar to Photoshop CS or later, use 0.1% (0.001).
histogramMode

Type: Aurigma.GraphicsMill.HistogramMode

HistogramMode value that specifies how to build the image histogram.

Remarks

You can also use Levels class to apply this correction (with Auto property set to true).
