Hi, Here is a nice 18K photo: http://www.openjpeg.org/samples/Cevennes2.jp2
GvSIG does not open it. It generates 37493 characters long error message instead and the error window is (perhaps) impossible to close withour killing gvSIG. Kosmo does open this image as well as my non-georeferenced aerial images. However, Kosmo is placing the image into coordinates (0,0) even is they have corresponding world file. ER Viewer 7.0 does not get georeferencing from world files either so maybe we will out of luck. But Kosmo is close to success. All that is missing is to slide and scale the image according to .j2w file values. I have used JPEG2000 world files in a standard way. I have copied the original .tfw file into .j2w and placed it into the same directory than .jp2 image. Gdal is recognising .j2w file as well as some other programs. Some programs don't read the world file. -Jukka- > -----Alkuperäinen viesti----- > Lähettäjä: edgar.sol...@web.de [mailto:edgar.sol...@web.de] > Lähetetty: 21. syyskuuta 2011 14:37 > Vastaanottaja: OpenJump develop and use > Aihe: Re: [JPP-Devel] OpenJUMP with JPEG2000 test results > > does gvsig 1.11 open plain jp2 for you? > do you have a small plain jp2 to play with? > > ede > > On 21.09.2011 11:57, Rahkonen Jukka wrote: > > Hi, > > > > I had a test with OpenJUMP-snapshot20110920-r2420-bin.zip > on Windows Vista 32-bit and Windows XP Pro 32-bit and jre 1.6.0_27. > > > > Test 1. > > GeoJP2 (.jp2) images created with Kakadu kdu_compress. > Original images have been geotiffs and in this case > kdu_compress is creating a GeoJP2 file with included > georeferencing info. > > Result: 1-channel (black and white) and 3-channel images > (RGB) are shown fine. > > > > Test 2. > > JPEG2000 images created with ER Mapper Image Compressor 7.2 > from georeferenced images (tiff files with tfw). > > Result: OK > > > > Test 3. > > Non-georeferenced .jp2 files created with Kakadu and ER > Mapper Image Compressor. > > Result: OpenJUMP seems to open the images (no error > messager) but it does not show them.
