I do have B&W tif's (1-bit coded), and when I want to get those rendered
by mapserver, I obtain bad restitution within some zoomscales. The map
image is also B&W. I would prefer it to be in greyscale.
Can I easily do this with mapserver.
To have this working, I transformed my tiff manually with photoshop to
have an 8-bit greyscale image. Can I do this easily with the libtiff tools ?
And then I applied gdaladdo to get overviews. This last operation seems
to be necessary to have a good rendering.
Did some of you have similar problems and got it work ?
