    Public Methods
     NameDescription
    Public MethodAdjustLevelsAdjusts 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).

     
    Public MethodApplyGaussianBlurOverloaded. Applies a Gaussian blur to this GrayscaleBitmap.  
    Public MethodApplyGlowWhen applied to a grayscale mask built from a color image using the ToGrayscaleBitmap method, modifies it so that the result can be used as a transparency mask to produce Glow or Soft Edges effect.  
    Public MethodApplyLicenseKeyApplies a license key to an instance of GrayscaleBitmap.  
    Public MethodAutoContrastOverloaded. Modifies pixel intensities such that available range of values (0..255) is fully covered.  
    Public MethodClearOverloaded. Clears the GrayscaleBitmap with the specified value (from 0 to 255).  
    Public MethodClipCreates a new GrayscaleBitmap with a fragment of the image.  
    Public MethodCloneCreates a new GrayscaleBitmap with a copy of the image.  
    Public MethodDisposeClean up any resources being used.  
    Public MethodInvertColorsInverts the pixel colors from black to white and vice versa.  
    Public MethodSetDpiOverloaded. Changes the physical resolution of the image.  
    Public MethodShrinkPixelFormatChanges pixel format from 8 bits per pixel to lower value with two-dimensional error diffusion.  
    Public MethodToGcBitmapOverloaded. Creates an instance of the GcBitmap class from the current GrayscaleBitmap.  
    Public MethodToShadowBitmapOverloaded. Creates a semi-transparent GcBitmap from the current GrayscaleBitmap.

    This method treats the current GrayscaleBitmap as a transparency mask, regardless of the TransparencyMask property value.
