Rotate images?

Postby der_skeptiker on Fri Mar 19, 2010 11:50 pm

Hi,
I'm very new to FPV. My most important question is: How can I rotate images while displaying them (no batch; without loss of information)? Can FPV save them then as a new/the same file?
Pictures of my camera have no rotation information in their EXIF data :(

The program does not edit or save images at this time, it is strictly read-only. Indeed it relies on EXIF orientation information to rotate image properly for display. If your camera does not write orientation information there is no immediate solution with FPV.

I'm planning some additional function, manual rotation (in addition to the existing automatic rotation) may be added in a future version.

Hi,

As I have also photos with lacking and/or wrong orientation tags it would be nice to know, if user could select to write correct orientation tag into sidecar (XMP?) files. That way he/she wouldn't have to edit original JPG and RAW image tags inside those files. It's annoying to always rotate some images that don't have this EXIF data in them.

Metadata editing inside original photos seems to be such a risky business... :cry:

You can use ExifTool to fix the orientation tag within your files, if it's wrong or missing for some reason.

Yep ExifTool and ExifToolGUI seem to be very capable in doing this. But even author of ExifTool suggests you should make backup of the original files - especially if you are editing RAW files.

So if a image management/viewer/editor software can support sidecar xmp files, could these files be used to have orientation info in them. For example if sidecar file contained orientation info it would override all exif orientation data - otherwise exif data was used? Just a thought from a non-programmer! =) So if you would use sidecars to add description, title etc. metadata, why not use them for orientation data also? That way you could leave original RAWs untouched.

An on-screen rotation feature has been added some time ago: hit the [Ins] key or [Shift+Ins] to rotate the image on-screen.
