[gdal-dev] warp/trsnalte a specific src_ovr without alpha band

[Idan Miara]

Hi,

I have a RGBA raster with overviews, I'd like to cut an extent from a
specific overview into a new YCbCr JPEG raster.
I want to drop the alpha band (I don't need it and it is not supported in
YCbCr).

I couldn't find a way to do it because:
1. with gdal_translate I could choose bands (RGB) but I couldn't given a
src_ovr,
2. with gdalwarp - I could choose a src_ovr but not to drop the alpha band.

Kind regards,
Idan
