Raster to Vector [message #43371]

Hello there,

A have a TIF image and I want to make a raster to vector conversion of
some DN values.

I'm using rtf_doit:

values = [4096] ; the DN I want to convert
l_name = [values]
out_names = dir+'testimg_' + $
strcompress(string(values),/remove_all) + '.evf'
in_memory = lonarr(n_elements(values))

envi_toggle_catch
envi_doit, 'rtv_doit', $
fid=fid, pos=pos, dims=dims, $
values=values, l_name=l_name, $
in_memory=in_memory, $
out_names=out_names

But I have no success... I have the message:

% Subscript range values of the form low:high must be >= 0, < size,
with low <= high: <BYTE ( 179)>.
% Execution halted at: EVF_INIT_FILE

What could be the problem???

Any comments welcome.

Cheers,
Julio
