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.
