ERR PANO TOO LARGE
When I export a panoramic picture, the software reports an error:
ERR PANO TOO LARGE
Reset the adjustments through the edit menu.
I can confirm issiue with ERR PANO TOO LARGE for 10+ JPEG photos. Did not run out of memory. I wouldnt mind if pano from multiple photos took long to export
Thanks for the reports!
Just to confirm, did you get a good result with a previous version of Xpano, or is this the first time you're testing the app now with the 0.18 version? I have added this check in 0.18 because previously the app was crashing for large panos.
I'll have a look and try to implement it so that the pano is exported at a maximum supported resolution (possibly selectable in the options).
If you don't mind sharing your pictures, I'd be happy to test the new approach on them, you can send me a link on email / matrix chat (links on https://krupkat.cz)

Is this limitation of OpenCV or some engine in the app? I admit my photos were JPEGS ~18MPx each straight from camera with no edits [I was testing if your app will suit my needs].
If this is limitation of the app, please point me to the parts of code/module responsible for holding/handling of stiched panorama. Any information about algorithm/architecture of your app will be welcome. I have no familiarity with OpenCV API [or GUI you have used] but I have some experience with bitmaps & graphics in boost/Qt soo... when I will have some free time I might try to help :)
Cheers
I also encountered this issue, just made this PR https://github.com/krupkat/xpano/pull/129 that makes the maximum panorama size customizable. This should at least help a little bit :)
This is great, thanks a lot! :)

The error was coming from OpenCV, but honestly I was not able to reproduce it when I tried recently... when I disable the max pano size and try some large pano (e.g. by rotating a perspective projection in so that it stretches a lot) I get an out of memory exception and surprisingly, the app survives, just cancelling the task.
On some panorama settings (perspective for example), I also get OOM errors from Opencv (but the app doesn't crash!). But using spherical everything works fine. I guess this might be related to how the images have been taken (more suited to spherical), but it's still strange that perspective needs so much more memory.
