Why are my filters disabled

Hi,
I've been using Gimp for a good while, but today I tried to edit a TIFF image of an old document with lots of speckles on it. No problem - use the despeckle tool! However, when I try to invoke it, all the enhance filters are greyed out. I then tried a similar file, this time a jpeg and the filters are all enabled. I then thought maybe it doesn't like to image type so I saved it as a PNG file, killed Gimp and restarted. The filters are still disabled.

Can someone suggest why the filters are disabled for this image, and how I can fix it?

Many thanks

Bill

It is probably a greyscale tiff. Many filters only work on RGB. Try image>mode>RGB then you should be able to use the filters.

The image should be in RGB mode for these tools to work. Check Image -> mode.
