GrapeCity.Documents.Imaging アセンブリ > GrapeCity.Documents.Imaging 名前空間 > GcBitmap クラス > AdjustLevels メソッド : AdjustLevels(UInt32,UInt32,UInt32,UInt32,Single) メソッド
The input black point in 32-bit ARGB format (the Alpha channel is ignored).
The input white point in 32-bit ARGB format (the Alpha channel is ignored).
The output black point in 32-bit ARGB format (the Alpha channel is ignored).
The output white point in 32-bit ARGB format (the Alpha channel is ignored).
The value of gamma correction.
Adjusts the levels of an image histogram.

The method maps the input range of values (blackPoint..whitePoint) to the output range (outputBlack..outputWhite) using the specified gamma correction (midtone).
