Add multiple file support #28

Closed srhardie closed 10 months ago

srhardie commented 10 months ago

RFE - Are you able to please add keyboard shortcuts for moving forward/backwards through multiple image files in a directory. Currently if there are multiple images in the same directory, from Nautilus file browser I open the first image file for viewing. Then to view the second image, I need to use the 'Replace Image...' dialog or go back to Nautilus and double-click on the next file. This is slow for moving through dozens or hundreds of image files in a directory. Perhaps as mentioned in the vipsdisp TODO list, something like Shift-left and Shift-right? Similar to Gnome Image Viewer (EOG) using left/right arrow keys to move through multiple image files.

Fedora 38, vipsdisp 2.6.3 as a flatpak from flathub.org

Hello @srhardie, yes this has to be the most requested feature.

I've been making vipsdisp as a new image view window for nip2:

https://github.com/libvips/nip2

That thing needs updating for gtk4, and image display is probably the bit that's changed most since gtk2. Since this will be a widget in a spreadsheet, it won't need multiple image support.

... having said that, I agree that as a lightweight standalone viewer, it would be useful for vipsdisp.

... I decided this feature was more interesting than anything else I had planned today, so I hacked in basic support. There are a few things to look at still:

it uses alt-left and right
if you run vipsdisp a/b/c.xx, then left/right cycles though all files in directory a/b
if you run vipsdisp a.x b.y, then it cycles between those files
need to add multi-file drag and drop, and multi-file copy and paste
we could improve caching of recently opened files
could improve killing of background loads of abandoned images

git master vipsdisp supports drag and drop and copy paste, so you can just drag files from nautilus. Proper multi-file support is better, of course.

Thanks! This will be immediately useful in a large image processing project.

I compiled from master and tested it out. Cycling through image files using alt-left/right works great.

Looking forward to an updated flatpak on flathub when you can.
