[gdal-dev] Use of gdalwarp to make GeoTiff transparent is flipping the image

[Liglio]

Hi,

I used the command "gdalwarp -dstalpha -srcnodata 255 -dstnodata 0 image.tif
transp_image.tif" to make a color GeoTiff Image became transparent, but it
is flipping the image horizontally. What I am doing wrong? Can I unflipp the
image?

Thanks.
