[FWTools] [Gdal_translate]colorimetry changes

[force verte]

Hi,

I try  to assemblez several TIF to make a unique picture.
I use this command:

C:\GDAL\SCAN25_SCOT>gdalbuildvrt truc.vrt C:\GDAL\SCAN25_SCOT\*.tif
> -srcnodata "0 0 0"
> 0...10...20...30...40...50...60...70...80...90...100 - done.
>
> C:\GDAL\SCAN25_SCOT>gdal_translate -of GTiff C:\GDAL\SCAN25_SCOT\truc.vrt
> C:\GDAL\SCAN25_SCOT\truc.tif


But a part of the picture gets a lots of red pixels.

Does someone know why?

Thanks
Flu
