Not all pages rotated from multi-page TIFF images

Post by wmdmer » Fri Sep 18, 2015 6:30 am

Hello!

I have the issue with the last ver (for now it's 2.34). When trying to rotate all pages from the multi-pages TIFF only the last observed page is rotating.
I haven't success to find any setting for this in preferences.

Am I doing something wrong or observing a bug? Or maybe it's a feature?

If you are rotating the pages (or performing any other editing) by stepping through the pages, you need to resave the file every time a page in the file is changed otherwise the changes will be lost... If the file has a large number of pages resaving each time could become very slow.

Or are you rotating the pages in the file using a batch operation, if that is possible?

Edit:

In a quick test, the pages of a multi-page TIFF were rotated correctly using a batch operation... [Using XnConvert for my test].

Oh yea.. if there are 20+ pages am i need to resave the image after I step each page?

It's uncomfortably, because for example if I step to another file I got the message: "The document was changed - save it?" - well I press yes, but only the last observed and rotated page would be rotated. And I can choose "do not ask me" - thus XnView will save only the last rotating.
While stepping pages inside the file regardless of rotating any page this message never appear. So i suppose rotaing the single page shoud be significant edition for this message, which I can follow the setting YES and "do not ask again"

I suppose I could step pages inside one TIFF, rotate single (or maybe all) page, and the changes should be automatically written do disk.

No, batch operation is not helpful if I have the scanned document 20+ pages where some pages I need to rotate 90° left, some 90° right, some 180°.. This operation always handy.

Yes...

That seems a valid comment, could you post that separately as a suggestion so that Pierre can consider it?

When I looked at a similar situation five years ago -- stepping through the pages of files containing around 100 pages to make selective edits -- I decided the best way was to extract the images from each file to a folder, step through the images in the folder quickly making any required edits and resaving any page that was edited, and then creat a new multi-page files from the final folders of images.

Overall that seemed the best way for processing a large number of multi-page scans, and there was a possibility to use NConvert scripts to automate some of the operations such as extracting the images in each multi-page to a folder, and creating the new multi-page file from each folder of images.

Ok, I got your point:
Onened another thread: Proposal to save multi-page TIFF when single page changed.
It's ok to close this one
