Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: OpenJUMP - Menu - File Group: None Status: Closed Resolution: Fixed Priority: 5 Private: No Submitted By: mentaer (mentaer) Assigned to: Nobody/Anonymous (nobody) Summary: problems with old image loader Initial Comment: OpenJUMP 1.5.2 (and RC 1.6?) seem to hang for some image types according to a user report in the forum: https://sourceforge.net/projects/jump-pilot/forums/forum/729479/topic/6269315 I attach the two images send by the user: - Scan-121105-0002.tif: can't load through "Add image layer", but works fine with "Sextante raster": - E020N30_ql.png: example of PNG image that "hangs" OpenJUMP (also with Sextante raster) ---------------------------------------------------------------------- >Comment By: mentaer (mentaer) Date: 2012-11-28 05:39 Message: turns out the reporter in the forum entry was kind of a Pro, because I wrote again with his findings which confirm ours. Interesting additional info is that he used a photoshop tool for the georeferencing. ================= By: klonuo Hi Stefan and Michael TIFF image attached in my previous reply is scanned and georeferenced. It looks like the problem is with this particular georeferenced image made by "Geographic Imager" for Photoshop. TIFF images georeferenced with gdal for example, have no problems. Also some not georeferenced TIFFs can be loaded some won't >From very quick investigation, perhaps uncompressed TIFFs can't be loaded with "Add Image Layer". Cheers from http://sourceforge.net/projects/jump-pilot/forums/forum/729479/topic/6269315/ ---------------------------------------------------------------------- Comment By: ede (edso) Date: 2012-11-28 03:10 Message: then the user in the forum thread must be mistaken. he wrote: "TIFF files were just scans. Here is link to example file that can't load through "Add image layer", but works fine with "Sextante raster": http://dl.dropbox.com/u/6735093/temp/Scan-121105-0002.tif"; jukka: you can try the latest snapshot. it should give you a more meaningful error on trying to load the tiff with 'add image layer'. ..ede ---------------------------------------------------------------------- Comment By: Jukka Rahkonen (jratike80) Date: 2012-11-28 03:05 Message: About geotiff validity, it is a valid geotiff but georeferencing with GCPs is not so common. Use gdalinfo for seeing the details. Myself I would use gdalwarp for converting the image into more common geotiff type. ---------------------------------------------------------------------- Comment By: Jukka Rahkonen (jratike80) Date: 2012-11-28 03:01 Message: Tried again with 64-bit Windows 7 and 32-bit Java 1.6.0_37. Png image is opened but tiff not. Resulting errors in attachment. Tried with Add image layer and File-Open-File. ---------------------------------------------------------------------- Comment By: ede (edso) Date: 2012-11-28 02:53 Message: ok, just read the forum thread.. obviously Michael already found out pretty much the same already. we should really stick with bug ticket on issues like that, as these are the only one communicated to the mailing list and devs keep updated this way. .. anyway, two things A) can't the user simply deliver a worldfile for the tif? B) as the 'Add image layer' does not hang at all i close this bug as fixed. ..ede ---------------------------------------------------------------------- Comment By: ede (edso) Date: 2012-11-28 02:47 Message: my guess would be it's the usual problem with jai. the user probably has some other versions of jai jars laying around in jre folder and these take precedence over our own. ..ede ---------------------------------------------------------------------- Comment By: ede (edso) Date: 2012-11-28 02:44 Message: hmmm, tried with current trunk 3085 from within eclipse on win7. used 'add image layer' on both attached files and _nothing_ hangs. E020N30_ql.png loads fine showing some kind of map with legend and such. Scan-121105-0002.tif runs and tells there were errors. Attributviewer says see screnshot below: 'Neither geotiff tags nor valid worldfile found.' does the tiff has the proper tag? ..ede ---------------------------------------------------------------------- Comment By: Jukka Rahkonen (jratike80) Date: 2012-11-28 01:37 Message: One more thing about the tif file, it is georeferenced by attaching four ground control points into the GeoTIFF metadata and I doubt that the old image loader supports that system. ---------------------------------------------------------------------- Comment By: Jukka Rahkonen (jratike80) Date: 2012-11-27 21:52 Message: Some test result follow. The png image contain some raw data (bin8, from Photoshop?). I rewrote the file with GDAL into another png file and OpenJUMP can open it. The same happens if I save the png file again with IrfanView. The original png is obviously valid but there is something in it that makes OpenJUMP to fail with it. The tif file is using LZW compression which may make troubles. ---------------------------------------------------------------------- Comment By: mentaer (mentaer) Date: 2012-11-27 09:34 Message: I could not upload the tif file so here the link (maybe it is still there then... but I have it on my machine too) http://dl.dropbox.com/u/6735093/temp/Scan-121105-0002.tif ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=679906&aid=3590407&group_id=118054 ------------------------------------------------------------------------------ Keep yourself connected to Go Parallel: INSIGHTS What's next for parallel hardware, programming and related areas?
