Reading animated gifs?

[seedpress]

Is it possible to read AND write animated gifs in Octave by using imread and
imwrite (or any other function)? I know that Matlab's imread function is
supposed to be able to read them. But, so far, my code has failed to do it
within Octave.

My code:

g_name='example-gif-anim.gif';
out_name='example_res2.gif';
gI=double(imread(g_name, 'frames', 1))/255;
imwrite(gI,out_name);

I keep getting the following errors:

fn = example-gif-anim.gif
error: imread: invalid image file: Invalid call to __magick_read__.  Correct
usage is:

 -- Function File: M = __magick_read__(FNAME, INDEX)
 -- Function File: [M, COLORMAP] = __magick_read__(FNAME, INDEX)
 -- Function File: [M, COLORMAP, ALPHA] = __magick_read__(FNAME, INDEX)

error: called from:
error:   C:\Octave\3.2.4_gcc-4.4.0\share\octave\3.2.4\m\image\imread.m at
line 77, column 7
error: evaluating argument list element number 1

octave-3.2.4.exe:6> animate example-gif-anim.gif
error: `animate' undefined near line 6 column 1
octave-3.2.4.exe:6>

I'm running Octave 3.2.4 for Windows MinGW32 in Vista(choke).

Obviously, if I can get the read and write functions working, I'll be
processing the images before writing. But now I'm just trying to get read to
work.

So, is reading an animated gif possible?
