Yes, this is limited to a single JPEG file as a source (not a VRT of several JPEG files for example), and if you use -co COMPRESS=JPEG without an explicit -co QUALITY setting. -co TILED=YES is supported. If you add "--debug GTiff", you'll see a "GTiff: Using special copy mode from a JPEG dataset" debug message when this direct mode is used. $ gdal_translatenin.jpg out.tif -co compress=jpeg --debug GTiff Input file size is 50, 50 GTiff: Using special copy mode from a JPEG dataset Even -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/gdal-dev
