hi, all,<br><br>I want to use vtkColorTransferFunction to map scalar value to two int values, the range of two variables is 0--4098. I want to know what the value range of R, G, B in vtkColorTransferFunction is . If the value range of R, G,G is
0-1.0, how to use vtkColorTransferFunction in order to map a scalar value to two int variables with large value range?<br><br>Thanks in advance!<br><br>Joye<br>
