0.92 "JPEG lossless transformations" not possible on 1 image

Post by GeorgD » Sat Oct 27, 2018 5:06 pm

XnView: MP 0.92 64 bit
OS: Windows 10.0.17134.345 64bit German

Open image from https://c.gmx.net/@327739707293172421/g ... 3Xps6b-6VQ (created using build-in panorama function of Samsung Galxy S7) - menu bar -tools - JPEG lossless transformations - rotate based on EXIF orientation field

Actual behaviour (bug): XnView shows "An error occured, the lossless rotation can't be executed". or sometimes even crashes. Same if you select other rotation or lossless crop.

Expected behaviour: Rotation and cropping works ;-) like it does for other files.

Note: Related to viewtopic.php?f=104&t=33669&p=140630&hi ... ss#p140630 but not the same, as that other issue is fixed and not affecting manually rotationg via Ctrl+Shift+R

Issue still present in v0.93.1 and still bugging as many pictures from the mobile are affected. Is there some lossless workaround?
