Description

Using gdal_translate to convert a JP2 file is very slow, the same for importing the file into GRASS. I am using JP2OpenJPEG driver, tested on Linux and Windows. A file to test with can be downloaded from here: http://www.uahirise.org/dtm/dtm.php?ID=ESP_020673_1750

More details in GRASS-user discussion.

r36357 should fix it "penJPEG: add a USE_TILE_AS_BLOCK=YES open option that can help with whole image conversion"
