Add mouse image panning

[diniamo]

Hopefully I didn't miss anything, but I couldn't find anything in the documentation mentioning this, nor any closed issues.

I'm switch to swayimg either way since there are too many issues with imv, but dragging the image with my mouse is something I do naturally so not being able to do that feels really bad.

Which version of swayimg do you use?
Dragging image with mouse was added in version 2.1.
Simply enlarge the image to a size larger than the window, press left button and drag.
But for now there is still a performance bug.

[diniamo]

Why is panning restricted to the bounds of the window? That doesn't make sense to me.

[artemsen]

Perhaps I misunderstood your question.
If the image is smaller than the window, it is always centered and cannot be moved outside the window using the mouse or keyboard.

[diniamo]

I am asking why that restriction exists, why can't I move the image however I want to?

[artemsen]

It is not a restriction, it is by design.
Just curious, why would you want to open an image and move it outside the window?
Want to see the window background? =)

[diniamo]

Generally because, I'd rather move the relevant part of the image to the center of my screen, instead of turning my neck to the side.

[artemsen]

Oh, I get it, this is a problem with large displays.
I will make this logic optional.

[diniamo]

Awesome, thanks.

Though yeah, the performance problems make this useless.

One question: why is it possible to have frames rendered where the gui (everything except the image, like the background, text) doesn't fill the window?

Try to build release version (it is by default in the latest master) and disable antialiasing (if you use it).

I don't get the question, sorry =)
Do you mean window decoration (title/buttons) or what?

[diniamo]

Welp, using latest fixes the issue I was trying to explain as well. Thanks again.
