[Gdal-dev] gdalwarp nodata

[Richard Greenwood]

I am using gdalwarp to merge some images. The images are rgb tiffs.
No-data pixels in the source image are r=255 g=255 b=255. I am using:
  -srcnodata  "255 255 255"
This masking seems to operate on a band by band basis, rather than a
pixel by pixel basis. Which is leading to some rather bizarre output
colors. Is my -srcnodata definition correct, or is there some other
way to deal with this?

Thanks,
Rich
