GNOME Bugzilla – Bug 306958
image comparison feature - side by side view
Last modified: 2018-07-12 00:06:03 UTC
f-spot need an image comparison feature. ie, display 2 or 3 pictures side by side to visually compare them to select the best... Like you would do with a couple of prints.
Apple's Aperature seems to do this quite well.

There are some pretty screenshots at http://www.apple.com/aperture/compare/compare.html It's actually Aperture, I'm bad at spelling.
Gabriel, thanks. I looked through the index page at compare/ too, and I think something like Aperture's stack feature (sliding opacity meter would be powerful, simple, and easy) would work great. Comparison side-by-side is already inherent in F-Spot's thumb browser, no? Some sort of "compact" function might aid in rough-eye-comparison. A filmstrip is definitely needed for navigation regardless of the comparison matter. (Is there already a bug for that? /me goes to search) (Perhaps this is best implemented as a view mode--thumbnails/tiles or filmstrip [Or are the F-Spot devs trying to get away from the canonical modes of viewing?])
A comparison mode would be great. It probably wouldn't be prohibitively hard to pack several ImageViews into a table. Should the zoom etc be linked for each of the views?
I think a zoom feature and/or magnifying glass? would be great to compare details in each photo

Linking the zooms between the windows is probably the right thing. I find it hard to imagine a time you'd want to zoom one and not the other...
for reference the iphoto comparison mode does not link the zooms
I can see situations where you would and wouldn't want the zooms linked. I would think having them linked by default would be good, but make it easy to unlink them (unbroken chain/broken chain) so the user can inspect parts of a specific image if they want, or if the photos are different resolutions. Linking the scrolling (if the zoom is linked, say) could also be nice (and irritating) in certain situations. Perhaps a three-mode button, with not linked, zoom linked, and zoom+scrolling linked would be appropriate.
Apple iPhoto does this side by side comparison marvellous, I have no clue of Aperture. I would love this feature. "Ever have two or more similar photos you need to choose between? In full-screen mode, iPhoto lets you compare up to eight photos onscreen at once. That makes it really easy to find the very best one in the bunch." {from http://www.apple.com/ilife/iphoto/features/fullscreen.html, there is also a screenshot over there} With a simple click, the chosen photo disappears and is replaced by a new photo. Eventually you will end up with the best photo of your collection. Keep up the good work!

Created attachment 136667 [details] [review] This patch introduces a new mode : side by side view This needs heavy testing !
Created attachment 136668 [details] this is the main file src/DoubleView.cs oups, I forgot the main file. I didn't manage to register it in git.
Omg! I love the stuff you've been putting out Vincent! Unfortunately, I can't get this to apply, so I can't test or review it. Could you look into it? We should get this ball rolling.
I pushed the patches, and fixed the build in http://gitorious.org/f-spot/mainline/commits/bgo306958 I love this, even if it needs some polishing. - the H/V button works, but choosing wether to be vertical or horizontal could be computed based on image sizes and allocations - the window doesn't theme correctly - by default, zooming and panning should be linked between the 2 views - when 2 images are selected (in browse mode), those 2 should be the ones displayed - if the filmstrip is not shown, it magically shows up when switching H/V - if the filmstrip is not shown, there's no way to pick images, as the left/right arrows moves both
Thanks ! I've committed on my clone - auto select H/V accoording to image size - fix filmstrip visiblity - when 2 images are selected, these are displayed I've checked left/right arrows when there is no filmstrip : as far as I understood, the arrows apply to the image that have the focus. Click anywhere on the second image, then the arrows moves the second image. Do you have the same ?
I've also pushed an experimental zoom sync between the two images. This introduces two problems : - the sync button is not very nice. It may confuse the interface - the panning sync is not handled, and would be difficult to. Since one picture may have an infobox and not the other one, or the central pane between the two pictures may have been moved, the displayed image size may be different between the two, and so is the panning.
We should definitely try to get this in by .7 (or whatever the next release will be called).
This is in http://gitorious.org/~vpomey/f-spot/vpomeys-clone/commits/bgo306958 by the way.
F-Spot has moved to https://github.com/f-spot/f-spot/issues If this Bugzilla ticket is still valid in a recent version of F-Spot, please feel free to post this topic as a ticket in the F-Spot project on GitHub. Closing this report as WONTFIX as part of Bugzilla Housekeeping as we are planning to shut down GNOME Bugzilla in favor of GNOME Gitlab.
