It is a 8 bit palletized image with less than 256 colours using NO COMPRESSION. Repacking it again with Irfanview, for instance, fixes it and reduces filesize from 1.3MB to 620 KB, using LZW compression and 550.2KB using DEFLATE (ZIP) compression.I don't know why XnView fails to load it though.

This way, the picture is not changed (really better for printing), and the picture is correctly displayed in the good renderer like XnView.It would be great if XnView had this function built-in ("Define picture Orientation" with the "F" pictures in or a "Rotate with EXIF" that from left to right, change or add the EXIF orientation (6 -> 1 -> 8 -> 3 -> 6 ...).What do you think of this?(I looked for this function in XnView and in the suggestion forum and did not find it).--Ben xnview Author of XnView Posts: 45555 Joined: Mon Oct 13, 2003 7:31 am Location: France Contact: Re: EXIF lossless rotation Post by xnview » Mon Sep 10, 2007 3:39 pm ben.che wrote:Hello,I did not find this rotation function in XnView.I think the best way to rotate a JPG picture, is to not rotate the picture (!) but change the orientation EXIF value of the picture.To change the orientation of the picture taken with my digital camera (which has no orientation sensor), I use EXIF Editor ( Thanks to this page ( I change or add the "orientation" EXIF value to 6 or 8.

For portable version I don't think this is a good decision. It should use a temp folder in application directory.Still noticed that the thumbnails for videos get stored there. However they do not get cleaned properly and stay there some times.Also noted some mysterious lock files from XnViewMP in that folder which never get deleted. xnview Author of XnView Posts: 45561 Joined: Mon Oct 13, 2003 7:31 am Location: France Contact: Re: Temp folder issues Post by xnview » Wed Oct 26, 2016 8:29 am i don't use temp folder, perhaps it's ffmpeg if you use it Pierre. jadO Posts: 490 Joined: Wed Apr 29, 2015 6:36 am Re: Temp folder issues Post by jadO » Wed Oct 26, 2016 10:47 am xnview wrote:i don't use temp folder, perhaps it's ffmpeg if you use itI don't think that is correct. In my temp folder I see:qtsingleapp-xnview-e789-1-lockfile what ever this meansanda lot of files like "xnview_E14008.png" which are the single thumbnail images.FFMPEG is not installed and portables as well, so using the system temp folders is bad. But even more worse is that the items do not get cleaned from the temp folder. xnview Author of XnView Posts: 45561 Joined: Mon Oct 13, 2003 7:31 am Location: France Contact: Re: Temp folder issues Post by xnview » Wed Oct 26, 2016 12:10 pm jadO wrote:qtsingleapp-xnview-e789-1-lockfile what ever this meansFrom QT api, so i can't change thata lot of files like "xnview_E14008.png" which are the single thumbnail images.ok, created by ffmpeg, should be deleted by QT api Pierre. jadO Posts: 490 Joined: Wed Apr 29, 2015 6:36 am Re: Temp folder issues Post by
