Issue when image becomes smaller (when zooming out) than viewport

[jonathangerbaud]

Hello,

First of all, let me say that your library is amazing!

Now, I'll try to explain the issue precisely. The problem occurs when setRestrictBounds is set to false. When I zoom out and the image becomes smaller than its original size, then gestures (rotation, panning) are almost impossible and seems no longer enabled. Only zooming in seems to work (but not as efficiently as usual behavior).

It's like there is some condition that prevents gesture when the image is smaller than its original size.

And it's quite annoying for user experience.

I tried several combinations of settings but nothing seems to fix this issue.

Here is the actual settings configuration I'm using:

      source.getController().getSettings()
                .setMaxZoom(5f)
                .setPanEnabled(true)
                .setZoomEnabled(true)
                .setDoubleTapEnabled(false)
                .setRotationEnabled(true)
                .setRestrictRotation(false)
                .setRestrictBounds(false)
                .setOverscrollDistance(0f, 0f)
                .setOverzoomFactor(2f)
//                .setFillViewport(true)
                .setFitMethod(Settings.Fit.OUTSIDE)
                .setGravity(Gravity.CENTER);

Maybe I missed a settings, or there is some trick to use to make it work. Any way, if you have any clue, let me know about it.

Thank you in advance for your time!

I'm experiencing the same issue with the following configuration:

gestureView.getController()
        .getSettings()
        .setMaxZoom(3f)
        .setRotationEnabled(true)
        .setRestrictBounds(false)
        .setFitMethod(Settings.Fit.INSIDE)
        .setOverscrollDistance(2f, 2f)
