Pan and zoom SVG (or anything really)
Download and include movey.js in your scripts.
Hook up movey to a target you want to interact with by using data-movey-target attribute.
Use data-movey-reset attribute on a button which you want to use for reseting your target back to the initial position.
Movey exposes 2 methods for setting and getting settings.
Straight forward, returns the settings object.
You can override the default settings by calling useSettings() and passing in an object with your settings.
The default settings object looks like this:
{
zoomMin: 0.5, // minimum zoom out
zoomMax: 3, // maxium zoom in
zoomStep: 0.2, // how much one step zooms
transitionAllowed: true, // is transition allowed ?
transitionString: 'transform .3s linear' // the transition string which is used if transitionAllowed is true
}
