[META] Image viewing and saving - nonAPI

[gsantner]

General information

• App version: 0.2.1

• Save images

  • use correct extensions (jpg, png, gif)
  • make sure parents exist Share to Telegram (or anything else) not working #137
  • make sure write permission given

• Picture ContextMenu improvements

• Optional: Lightweight picture viewer (jpg, png, gif)

  • Very optional: Swipe pictures of post if there are multiple

Correctly save images

Currently everything is saved as *.png file when clicking picture -> Context menu -> save.
The images should be saved with the proper extension (jpg/png/gif/..)

Picture ContextMenu improvements

Currently

1. Long-Click on Picture in WebView
2. Context menu gets opened

Expected

• Download picture -> Notification which opens the system picture viewer with the picture
• Show picture (New): Some kind of dialog or popup, which just shows the picture, but leaves WebView as it is
• Allow to copy url of image (Copy image URL #136) - just like normal links, code exists
• Allow different file formats: jpg, png, gif

I guess some "show image" feature will be/is implemented in the mobile site?

Edit:
Displaying a notification after download finished is a great Idea!
For "Show Image": We could take a look at https://github.com/davemorrissey/subsampling-scale-image-view
Different file formats: Related to #102

[gsantner]

Show image is one of my use cases: I spend the most time on diaspora looking on pictures. Sometimes there are really good pictures, but I can't really see anything. So an built-in context action for viewing (and allowing zoom-in) would be great.

Library: Don't know how big the mentioned one is, but I think some lightweight (without much options) is enough. But it should handle the most common (mentioned above) file extensions.

[vanitasvitae]

The library I mentioned handles images, gifts and I think even webms.

It would be nice, if the imageViewer would offer swipe actions that allow to go to the next/previous image in the post (if there is one). I don't know, how hard that would be to accomplish without the API though.

Any contributions are appreciated on this issue!

Just came across this which could help to implement the "Copy link to clipboard":

@noplanman: copying the image link to clipboard is no big deal, there is no extra app needed for that, but thank you anyway :)

[noplanman]

Oh, I didn't post it for the extra app, but for the part "Option 3: Extend the Share dialog".
As for now, there is no such option on the share dialog, meaning I need to select "Open in external browser", then copy the URL from there.

[vanitasvitae]

Yeah, I meant, adding such an option to the share menu is no big deal ;)

[noplanman]

Aaaah, great! 😃

[vanitasvitae]

I just added an option to copy image urls to clipboard :)

[gsantner]

@vanitasvitae Nice :D
We could also inherit&override from the ContextMenu of normal links (don't know how you did :) )

[vanitasvitae]

Its only ~5 Lines of code. I don't think its worth to inherit something there ;)
Edit: I just added another switch case without body right before the copy link case. Thats about it. So in fact, it actually uses the copy text code.

Thanks! I use this so much... Can't wait for the next version 😇
