All
I need to convert a TIF to a compressed BMP. I can get it to a bmp, but not a compressed BMP. Here the command I an using.
nconvert -out bmp *.tif
For some reason, my -help just scrolls through too fast to see. |more doesn't work to pause it.

Or maybe a compressed RGB
nconvert -out sgi *.tif
This command gives an error. Says this file cannot be converted to this format. But when I use Xnview, it works great.

Try with -truecolors

That worked:
nconvert -out sgi -truecolors *.tif
but they are uncompressed. Is there a command for compressing the RGB or BMP?
Thanks

RGB bmp doesn't support compression

That's odd. If I convert a tif to RGB in Xnview, the file size goes from 1.2MB to 34Kb. Is there any way to convert a tif to RGB or BMP and have the file size small?

I figured out a way.
Nconvert -out bmp -c 8 *.tif
Makes the BMP very small. Works since there are only 4 colors in the TIF
Thanks

Your picture is perhaps not in true colors?
