Hi, I have four tif input files, these have 3 bands RGB and are JPEG compressed. No null data set.
My goal is to mosaic these and then warp the mosaic. I start it with: gdalbuildvrt mosaic.vrt file1.tif file2.tif file3.tif file4.tif Then I warp the mosaic: gdalwarp -dstalpha -of vrt -overwrite -s_srs EPSG:32632 -t_srs EPSG:7791 mosaic.vrt warped.vrt Then I run gdal_translate -b 1 -b 2 -b 3 -b 4 -co BIGTIFF=YES -co COMPRESS=DEFLATE -co ALPHA=YES -co TILED=YES -co NUM_THREADS=ALL_CPUS warped.vrt output.tif The final tiff file has black edges. What's wrong with my procedure? How to avoid this?
