Hey guys:

How can I let resliceimageviewer display a colored image? I know that vtkResliceImageViewer can setup lookup table. But I need to blend two images after map image to color.

I use DICOM reader to read image data. Then I create a lookup table to change image data into RGBA. Next I blend image with a mask to display the region of interst. Everything works fine except vtkResliceImageViewer can’t display color. Can someone help me?

Or does someone know how to create a Lookup table that output origin image?

Cheers  
Zheng
