[scilab-Users] How to load 16bit TIFF image in Scilab?

[Charlie Warner]

A bit more information about ImagJ, from the documentation:

"16-bit and 32-bit grayscale images are not directly displayable on 
computer monitors, which typically can show only 256 shades of gray. 
Therefore, the data are mapped to 8-bits by windowing. The window 
defines the range of gray values that are displayed: values below the 
window are made black, while values above the window are white. The 
window is defined by minimum and maximum values that can be modified 
using Image>Adjust>Brightness/Contrast."

Is this the sort of function you are looking for?

      Have a look at ImageMagick
      or possibly libTIFF

      
    I already played with ImageMagick but I don't know how to use it to
    convert in a format scilab can import.

    As for libTIFF, I am currently playing with it in an attempt to
    write my own import function for scilab.

    

      In the Linux world, GIMP or ImagJ may
      accomplish what you are wanting to accomplish.

    
    Gimp (at least the version I have on Fedora13) does not support
    16bit.
