  image_map... (Message 1 to 3 of 3)

I'm trying to use a basic gif image for a map on a block, but I get the
following error...

"error: Interlacing in GIF image unsupported."

Here is the code I'm using...

box { <-2, 0, -.5> <2, 5, .5>
  pigment {
    image_map {
      gif "<file-name>.gif"
    }
  }
}

I just wanted to get a feel for how the process worked before putting in
the modifiers, but couldn't even get that far.  What am I doing wrong? I
do have the image in the same directory as the POV file.  I've even
tried two or three different image files...

Any help is much appreciated and needed.

Thank you,
Saif

There are actually different types of gif files.  Some are interlaced and
some are not.  Pov is not designed to read interlaced gif files.  Do get
arround this, open your picture in an 2d paint program.  Go to the save
options and specify not to save interlaced gifs (Paintshop Pro or LView Pro
will do this), and save your picture again.

  I wonder why. It takes about 2 lines of additional code to read
interlaced gifs (I know, I have made a gif decoder).
