Map Object... help

[kuporific]

Hey everyone,

I'm trying to use the "Map Object..." filter under "Filters > Map > Map Object..." and sometimes it's available, but most of the time it's grayed out. I can't figure out under what circumstances I can and cannot use "Map Object...". I thought maybe it depended on file type, but that doesn't seem to make a difference, and I thought maybe the image had to be a square, but that doesn't seem to do the trick either. I'm using the Windows version of GIMP (Windows 7). Does anyone have any suggestions?

Thanks,

One of the criteria to enable plugins is the Color/Greyscale mode of the image. "Map object" doesn't look enabled on greyscale.

Yes, that was exactly the problem, thanks a lot!

Could you explain the process? I'm a newbie to Gimp.
Thanks

In Gimp, an image can bee in either ofr three modes: RGB (full color, the usual mode), grayscale, and indexed (milited number of colors, typically for GIF). Many filters work only on RGB images, and appear grayed out when the image isn't RGB (or when applied to grayscale only things, such as channels and masks).
