[gdal-dev] Re-creating mask with nearblack

[Martin Ždila]

Hello,

I attempted to create a mask with nearblack -alg floodfill -setmask -nb 0
-white file.tif but near 90% it failed because of full disk space.

Will re-generating new mask remove (or overwrite) the old one? I wouldn't
like my geotiff to contain unused data unfinished mask.

If not, is there a way to get rid of it? I use JPEG compression so I don't
want to create a new geotiff from it by recompresing because it AFAIK would
reduce the image quality.

Thanks in advance
