Thanks for the quick help.

#26 How to use exif field Orientation?

Martin Herrmann — Fri, 27 Dec 2024 10:22:10 -0000

Hi, sure, if you select one or several images and press button "0" (zero) the images are rotated according to the exif orientation attribute .
It's also possible to auto rotate the images alteady during picture import .
Best regards
Martin

How to use exif field Orientation?

Sven H. — Thu, 26 Dec 2024 17:00:57 -0000

Is there a way to use the Orientation attribute from the jpg metadata? I mean for example for autorotation when viewing images.

#25 More keybindings / shortcuts in Comment window

That was fast. Thanks. No, I didn't known about IPTC.

Thanks for the nice feedback!
Wow, the first feature request after 12 years! :)
I added the requested keybinding Ctrl-l (add last comment) and documented the existing keybinding for Ctrl-c (add copyright), see revision 456.
BTW, I don't use the JPEG comment section any more, I completely switched to use IPTC data which offers more structure and thus better searches. Have you ever tried it?

Excellent tool - I have been using it for decades. Some more keybindings / shortcuts in Comment window would be awesome. Especially, Ctrl-l for "Last comment"

Speed up thumbnail generation for RAW files (incl. howto)

Alexander Wagner — Sat, 15 Oct 2011 14:22:25 -0000

Currently, mapivi uses ufraw to generate thumbnails for RAW files. However, the procedure is very CPU expensive and thus slow. From the command used

sh -c "ufraw-batch" --silent --wb=camera --black-point=auto --exposure=auto --create-id=also --out-type=png --out-depth=16 "--output=/tmp/magick-XXCyuyPe.png" "/tmp/magick-XXUdycXg"

it seems that mapivi is calling image magick which is calling ufraw as delegate. From the delecation it becomes clear that the slowness of this procedure results primarily from the fact that a full raw development is done here (note: even in 16bit colour depth!) then the image is scaled down to some 160x120pixels and reduced to 8bit jpg for the thumbnail usage. Thus, a very high quality intermediate step is used without any need or reuse.

Thus it seems possible to speed up thumbnail generation considerably by using cheaper procedures. Instead of developing the RAW one could just extract the embedded preview images already available and just scale them down. To extract embedded JPG preview images one might use

$ ufraw-batch --embedded-image input.nef --out-type=jpg --output=.thumbs/input.nef

This pure extraction is done in nearly no time, only scaling is left to consume CPU cycles. Probably, this call could be included in extractThumb in case no Exif-thumbnail is found.

Given the procedure currently used by mapivi one might on the other end consider it a feature: if the above mentioned expensive procedure is used one should probably just store the fully developed jpg file along with the RAW files and thus incorporate them in the general jpg-centric workflow of mapivi. One would then end up with the usual JPG+RAW type of images that work flawlessly with mapivi. It only seems advisable to tag those automatic files then with a special keyword for easy reference so the user can easily redevelop them in case necessary.

Renaming upon ingest

Alexander Wagner — Fri, 14 Oct 2011 17:21:49 -0000

Usually, Mapivi renames files upon ingest. This works perfectly in case of JPG files. It also works in case the SD Card contains JPG+RAW files. Unfortunately, Mapivi doesn't rename the images in case it finds a sole RAW file. This is quite unfortunate as it breaks the logic of renaming in this case.

Therefore, it would be great if Mapivi could adopt renaming procedures to all image files and not only if a proper JPG is available. This also makes increasing sense with the additional support of RAW in recent svn revisions of Mapivi.

Keyword hierarchy collapse/expand

Alexander Wagner — Wed, 17 Aug 2011 09:20:08 -0000

It would be helpful (especially for larger hierarchies of keywords) if it would be possible to collapse/expand the whole tree at once. Especially, collapsing can help in digging to the right category when adding/searching for subitems.

Enhance Lighttable

Alexander Wagner — Tue, 16 Aug 2011 09:55:09 -0000

Currently, the light table is only used for slide shows. It would, however, be very nice and helpful if the light table could be enhanced to some sort of intelligent clipboard that allows for all major image operations, ie. enhance it's menus by the context menu of the images thumbnail. This would ease up selections for web galleries export, copy to print from various sources and so on.
