Use rtv_doit to generat a vector file [message #94239]

I'm trying to use ENVI_DOIT to create a vector file from a raster file:

ENVI_DOIT, 'rtv_doit', $
fid=fid, pos=pos, dims=dims, $
IN_MEMORY = LINDGEN(N_ELEMENTS(values)), $
values=values, l_name=l_name, $
out_names=evffile

This gives me a vector file ，while there are so many vertices that it's difficult to edit .I would like to reduce the number of vertices when generating the vector file。

Does anyone have an idea how to do that?

Thanks, Peng
