Hi

I have a multipage tiff whose pages I can read just fine if I pass their index
as the second argument. However, if I specify the index thourgh the Index
option, it completely ignores it and reads only the first frame. For example:


> a1 = imread (impath, 1); # reads first page just fine
> a2 = imread (impath, 2); # reads second page just fine
> b1 = imread (impath, "Index", 1); # reads first page
> b2 = imread (impath, "Index", 2); # also reads first page (wrong)
> isequal (b1, b2)
ans =  1
> isequal (a1, a2)
ans =  0
