The LEADTOOLS Leadtools.RasterImage containing the grayscale image.
Use this constructor to initialize a WindowLevelEffect to work on the specified Leadtools.RasterImage. You can also use the default constructor and then call the FillGrayTexture method to apply to a LEADTOOLS Leadtools.RasterImage.
Both of these methods will automatically initialize the GrayTexture property with the required brush to use by this effect.
For C#/VB examples, refer to WindowLevelEffect.
