[Insight-users] itkImagetovtkimagefilter

[alba garin]

hi everyone,
i research more and i guess that i need to use the vtkImageQuantizeRGBToIndex filter in order to convert my RBG pixels to an index that after connecting the look up table of the filterand the output of the filter  with the viewer (vtkImageViewer2), it would work. this way i get color, but not an correct image. this is my code:vtkImageQuantizeRGBToIndex * imgRGB = vtkImageQuantizeRGBToIndex::New();    imgRGB->SetInput(_imageData);    imgRGB->SetNumberOfColors(16);   imgRGB->Update();   this->viewer->GetWindowLevel()->SetLookupTable(imgRGB->GetLookupTable());   this->viewer->GetWindowLevel()->SetLevel(-256);   this->viewer->SetInput(imgRGB->GetOutput());   this->viewer->SetSlice( 0 );this->viewer->render();
thanks,Alba

Hi everyone,
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.could anyone help me?thanks,
Alba
