Convert color-scale pictures to gray-scale ones
 
Dear All,

This is not a fluent problem, but hope someone has the experience.

I got contour pictures in color-scale, and wonder if we can change it to gray-scale. Please note that most photo softwares will change both RED and BLUE to dark color, which is not right for Fluent pictures. What we need is to change the color of RED->BLUE into WHITE->BLACK. I know that we can directly import gray-scale picture from FLUENT, but still hope there is another way to do this more conveniencely.

Many thanks.

Try using GIMP or even matlab can do that if you have the image processing toolbox

Just save the images using File->Hardcopy, choosing the gray scale instead of Colour.

Regards, ap

Or in the fluent gui pulldown, colormap, choose b&w scale rather than rgb.
