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

Re: Recolor to grayscale colormap scientific images
Hi all, It is strange, but it seems to not work in all cases. Look at these pictures (coming also from VTK): https://lh3.googleusercontent.com/-KvbShcKScXw/T4HPfrb7D0I/AAAAAAAAAh0/vhc_EbDdnJg/s800/3D_conrod_iso.png and: https://lh6.googleusercontent.com/-hg4_Bvt4PzU/T4HPeyv9MFI/AAAAAAAAAhs ...

Hi fmw42,
Thanks for the hint, it is perfect.
One remark, with image magick 6.4.0 (cygwin), -auto-tone is not recognized and the white becomes gray

Hi everybody, I would like to change the color of several images to grayscale. However, simple grayscale conversion is not suitable in my case because i want to convert scientific images with scalar bar from blue to red. So the red and blue all become black. I managed to do it with photoshop by ...
