Hello,
I got one problem: I have a bunch of uncompressed TIFF tiles, which I am
converting to compressed GeoTiff. I would
like to mask away the rgb(0,0,0) values.
However, when I use NODATA on my VRT dataset, there are JPEG artifacts
around the edges when rendering.
Is it possible to generate a transparency mask based on NDATA before
compressing, or is there any other/better way of
doing this ?
thanks,
- oyvind
