Hi, If I run gdalinfo against the JPEG2000 image in http://kartat.kapsi.fi/files/orto/etrs-tm35fin/mara_v_25000_50/2013/N53/02m/1/N5144H.jp2 the JP2ECW driver reports the blocksize as (256x256) and JPEG2000OpenJPEG driver reports that the block size is (1024x1024).
What interests me would be to know the fact that this image has only one JPEG2000 tile with a tilesize of (11754x11754). Is there any driver-independent way for getting this information? -Jukka Rahkonen-
