Hi everyone,</font><div style="font-family: Tahoma; font-size: 10pt; "><br></div><div style="font-family: Tahoma; font-size: 10pt; ">im working in a code of a partner in which he visualizes itk images with pixels with one component only (itk::OrientedImage<short,3>). I want to visualize a rgb image on it, (itk::Image<RGBPixel<char>,3>). I executed it and it visualize only a component of the rgbpixel, i guess, because i obtain a image in grayscale. i am trying to find out where the program restricts to visualize like this, and not in rgb, and i cannot find out. After using the filter the program sets all the vtk and qt components needed to visualize and does not do any change in the image, as far as i concerned.</div><div style="font-family: Tahoma; font-size: 10pt; ">could anyone help me?</div><div style="font-family: Tahoma; font-size: 10pt; ">thanks,</div><div style="font-family: Tahoma; font-size: 10pt; "><br></div><div style="font-family: Tahoma; font-size: 10pt; ">Alba<br><div>
