Re: Recolor to grayscale colormap scientific images

Hi, How do you explain that it works very well for the first image (fillet - sigma_x) and not for the last whereas they both comes from VTK with the same scalar bar color range ? However, the first comes from VTK->eps->pdf (vectorial) -> png Whereas, the second comes from VTK->png Laurent
