Feature description

On a small image, I want to zoom out the image to its minimum, that the image viewer fits the downscaled image on the device's screen.

In example, I have an image that has 184x184 pixels. So I want to zoom out the image to its smaller size. Since I have a 720p screen, I'll be able to pinch it towards the two finger to scale down image that matches the screen details.

Since Fossify Gallery does not have a feature to zoom out smaller images on a large screen like this, I'll not be able to see fit the downscaled image on a large 720p screen.

Why do you want this feature?

I use the zoom out feature, used for making a small icons or stickers.

Additional information

As an example from QuickPic Gallery, a modified version by WSTxda.
