I have a large collection (millions) of .png files (with .wld files) some
8bit/color RGB, others with 1,2,4 or 8bit colormaps, and some grayscale.
Since .vrt files cannot have different colormaps I'd like to convert them
into something uniform (probably 8bit/color RGB).
gdal_translate -expand is not valid with 8-bit/color files.
Is there any way of converting the files to something which can be used
in a .vrt, without knowing how many bands, and hence which arguments to
apply, to each file ?
Thanks,
