I enjoyed reading your post and am glad to see ZoomifyImage being used under PHP. I am in the process of updating the software and documentation (including a bug fix that Ciaran found) and wanted to know if it was OK to link to your post in my documentation? I am also adding a folder to the software for another user contribution and could add your PHP code also, giving you full credit of course, if you would like. Thanks for considering this, adam

Have you tried running the converter directly on the image, independent of the wrapper code? That might give a better idea of where the problem is occurring. You might also try running in verbose mode - I believe both php and python have a "verbose" switch that you can activate from the command line, usually by specifying a -v or -V flag. This would cause errors and such to show up in the output.

Here's a new one. Some TIF files work fine, others don't. The problem files create a picure directory, and a Tileset0 directory within it. Only one tile is created, and this is placed in the top level directory (where the overall structure is toplevel-picture-Tileset0). No XML file is created. The image wrapper code doesn't indicate a message - says it has processed the TIF file as usual, though you can it has had problems by the fact that it takes only moments. The exact same problem appears with some (but again not all) PNG files. So far (touch wood), I've had no problem with JPEGs. Any ideas ? thanks! Ciaran

Hi, sorted that out. It's now running sweetly on my laptop. There was no issue (under XP) with the chmod commands, incidentally. I've now ported it to my production linux environment, where it runs fine for the first image. But when I point it at the next image, it bombs out with [Errno 13] Permission denied removing ./pix/aaaaxxcc/TileGroup0/5-1-4.jpg where I have,of course, a zoomified file called aaaxxcc.jpg in the ./pix/ directory. Why would it want to *remove * files in a totally different directory when building a new zoomified image ? Thanks again! Ciaran

Are you able to process individual images (i.e. when you run the "python ZoomifyFileProcessor.py upload/imagename.tif" command, does it produce a result)? As for debugging, I'm afraid the wrapper scripts I wrote aren't quite that complete (or elegant, for that matter :) ). In lieu of such a command, you could try changing your error reporting level in php, as well as removing the "@" symbols from before the function calls in the code. The wrapper also executes a "chmod" command on the resulting directories (this is to fix a unix permissions issue) - you could try commenting out that line, as this might be something windows doesn't expect.

Hi, is there any reason this should't work in Windows ? I've installed Python24, got the PIL, edited the php files (running php and apache locally), run the converter, and it says it's converting the images (which it lists correctly), but when I go to see the results, there's nothing there.... Is there a debug command, perhaps ? Thanks a lot Ciaran

That's really pretty slick. This would be good to integrate with an Ajax tiled image browser too, as you wouldn't need flash then. I would like to give it a whirl on some of the stuff I'm doing for Animal Science if you don't mind me badgering you over the wall :-D Nice work.
