hi all, i want to display 2D image(BMP image).
This is my code

void main()
{
        vtkBMPReader *reader=vtkBMPReader::New();
	reader->SetFileName("image.bmp");
	reader->Update();

        vtkImageViewer *viewer=vtkImageViewer::New();
	viewer->SetInput(reader->GetOutput());
        //viewer->SetColorWindow();
        //viewer->SetColorLevel();
	viewer->Render();
}

i can display the image but the result is not good.(the image looks darker)
i believe the problem is in the SetColorWindow and SetColorLevel function.
how can i specify the parameter of those two functions so i can display the
image exactly the same as the original image??(i have tried some values but the
display still not good enough)



thanx a lot..
