Re: rgb2ind issue

[RT]

ok I posted it in the bug tracker.

https://savannah.gnu.org/bugs/index.php?54392

 If anyone knows of a workaround please let me know.

Thanks

I'm trying to create an animated gif using code I found at https://www.mathworks.com/matlabcentral/answers/94495-how-can-i-create-animated-gif-images-in-matlab

but I get an error

"error: Invalid call to rgb2ind.  Correct usage is:

 -- [X, MAP] = rgb2ind (RGB)
 -- [X, MAP] = rgb2ind (R, G, B)

Looking at the function calling structure on matlab:


https://www.mathworks.com/help/matlab/ref/rgb2ind.html

[X,map] = rgb2ind(RGB,n)
X = rgb2ind(RGB, map)
[X,map] = rgb2ind(RGB, tol)
[___] = rgb2ind(___,dither_option)

and octave:

https://octave.sourceforge.io/octave/function/rgb2ind.html

[x, map] = rgb2ind (rgb)

[x, map] = rgb2ind (R, G, B)

it appears that the current Octave implementation is not fully compatible. Unless there's already something on the bug tracker that I didn't see in a quick search, it should probably be logged as one:
