Ack! How wrong I can be sometimes. Forget I ever said the above about filter
all,1.
For one thing the comma causes an error, for another it never will filter or
transmit all anyhow.
I should have checked first before speaking. The 'filter all 1' will parse
and render but won't actually do any filtering, as you had seen already.
I wasn't too clear to begin with either I think. 24 bit and other such
non-256 color images cannot be "indexed" into POV-Ray since the whole thing is
based on the idea of using from 2 to 256 entries.
So I hope that clarifies it for the new user better. Makes more sense to read
the documentation than it does to listen to me most of the time.

| | I've an image map like:
| |
| | image_map { tga "foto.tga" filter all 1 }
| |
| | But the photo is still there. When I specify filter 1, 1, I get the
| | error: Keyword 'filter' cannot be used non color-mapped image.
| |
| | What's the problem?
