Enhancement: Adding zooming feature

[skadyrov]

Hi,

First of all, thank you for the amazing library! I implemented it in my photoalbum app, it is working great now!

I have a suggestion for this library: Are you thinking of adding a zooming feature? I found this nice library - Scale Image View on Github for zooming images. What do you think?

Hello!

Thank you very much enjoyed Spear. I carefully looked ScaleImageView, found to do very well. especially to show particularly large picture, this very great.

But I still have to be very sorry to tell you, to get Spear support ScaleImageView is very difficult, mainly because ScaleImageView not support Drawable.

In fact android.widget.ImageView meet most of our needs, in most cases we do not need to display large images zoom functions and features, so will ScaleImageView and SubsampleingScaleImageView role as a complement to the use may be more reasonable.

You mean SubsampleingScaleImageView cannot be integrated to this library? Any plans for implementing a zooming feature with just android.widget.ImageView?

[panpf]

yes！
