Detecting Touch Devices - carstenschaefer/ImagerJs GitHub Wiki

Specifies the function that ImagerJs calls to determine whether it's running on a touch device.

---

Configuration

imager: {
    detectTouch: function() {
        // Your code goes here
    }
}

• This function must return true or false.
• If the function returns true, ImagerJs assumes it runs on a touch device and will …
  • adjust its toolbar size (see property toolbarSizeTouch)
  • use touch-optimized settings for object control (see property objectControlsTouch)
  • add touch events
• If this function is not specified explicitly, ImagerJs will use its own touch detection mechanism.

Disabling Touch Detection

To disable touch detection entirely, simply return false from the detectTouch function:

detectTouch: function() {
    return false;
}
