Leadtools Namespace > RasterImage Class : MaxValue Property |
For every value between 0 and MinValue, Black (RGB(0,0,0)) will be used. For values between MinValue and MaxValue, the gray value to be displayed is calculated by : gray = (index - MinValue) * 255 / (MaxValue - MinValue).
index is the intensity value of the pixel. If the intensity value is > MaxValue, the color will be White. If the intensity value is < MinValue, the color will be Black. For those intensity values between MinValue and MaxValue, the above equation is used to determine the color, with index equal to the intensity value.
