Re: imread Win XP problems

[Stefan van der Walt]

Hi Jens

The 'imread' function doesn't like the spaces in the filename.

Put the following quick fix (named pathfix.m) somewhere in your
loadpath:

function f = pathfix(p)
        if (nargin != 1 || !isstr(p))
                usage("pathfix(p)");
        endif

        f = strrep(p, " ", "\\ ");
        if (strmatch("/cygdrive/", p) == 1)
                f = f(length("/cygdrive/")+1:end);
                f = [f(1) ":" f(2:end)];
        endif
endfunction

and change the "cmd=" line in imread.m to

cmd= sprintf("convert %s '%s' %s:%s 2>/dev/null ",
                  option_str, pathfix(fname), outputtype,
                  pathfix(tnam))


Hope that helps!

Regards
Stefan
