[gdal-dev] Re: [GDAL_TRANSLATE]Problem with colorimetry

[Chaitanya kumar CH]

Fab,

I found the problem.
There were some differences in color tables of your images. gdalbuildvrt
application from the latest GDAL version reports the issue when you try to
build the vrt file. You're advised to preprocess your rasters with other
tools, such as pct2rgb.py or "gdal_translate -expand RGB" to operate
gdalbuildvrt on RGB rasters instead.

The reason the red areas were occuring in different areas is that
gdalbuildvrt considers only the first file's color table.
