- The minimum and maximum values can be used to create a lookup table, for use in the WindowLevelCommand class.
- For signed images, the minimum intensity and the maximum intensity values can be negative.
- This class supports 12 and 16-bit grayscale images. Support for 12 and 16-bit grayscale images is available only in the Document/Medical toolkits.
- This command does not support 32-bit grayscale images.
For more information, refer to Grayscale Images.
