B4A Library Image Gesture View Library

Based on this Github repo, I adopted the view into a b4a library. The view mixes ImageView and FrameLayout with gestures control and position animation.
The goal of this library is to make images viewing process as smooth as possible and to make it easier for developers to integrate it into their apps. (Quoted)
Although the original view is rich in features, I scratched its surface with this library. It zooms in and out, rotates, translates and above all allows gestures by the user.
It is based on the .aar file and it should be placed in the additional libraries folder.

Here is a demo video:

Note that the rotation is 'jerky' because it is done with the mouse in an emulator. Using two fingers on a real device will run it smoothly.
******************************************************************************
It depends on: JavaObject and Reflection libraries.
Properties:
-Max Zoom: Float
-Min Zoom: Float
-Fit Method: List of String
-Set rotation enabled: Boolean
-Set Double tap enable: Boolean
-Set Double Tap Enabled: Boolean
-Set Zoom Enabled: Boolean
-Image File: String
-Enable Events: Boolean

Events:
-StateChanged (cMap as Map)
- StateReset (cMap as Map)
Methods or Subs:
-SetImageBitmap(Bitmap As Bitmap)
-SetImageFromAssets(FileName As String)
-SetFillViewport(Fill As Boolean)
-SetOverzoomFactor(Factor As Float)
-SetOverscrollDistance(Horizontal As Float, Vertical As Float)
- SetAnimationsDuration(Duration As Long)
-SetRestrictRotation(Restrict As Boolean)
-SetGravity(Gravty As Int)
-ZoomBy(Factor As Float, PivotX As Float, PivotY As Float)
-ZoomTo(Zoom As Float, PivotX As Float, PivotY As Float)
-RotateBy(Angle As Float, PivotX As Float, PivotY As Float)
-RotateTo(Angle As Float, PivotX As Float, PivotY As Float)
-TranslateBy(dX As Float, dY As Float)
-TranslateTo(X As Float, Y As Float)
- ResetState
- GetZoom As Float
-GetRotation As Float
-GetX As Float
-GetY As Float
-AnimateToState(TargetZoom As Float, TargetRotation As Float, TargetX As Float, TargetY As Float, Duration As Int)

Example:

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Private xui As XUI
End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    Private cvGestureImage1 As cvGestureImage
    Private btnReset As Button
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Layout")
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Private Sub cvGestureImage1_StateChanged (cMap As Map)
    Log($"Zoom: ${NumberFormat2(cvGestureImage1.GetZoom, 1, 2, 2,False)}x | Rotation: ${NumberFormat(cvGestureImage1.GetRotation, 0, 1)}° Position: ${NumberFormat(cvGestureImage1.GetX, 0, 0)}, ${NumberFormat(cvGestureImage1.GetY, 0, 0)}"$)
End Sub

Private Sub cvGestureImage1_StateReset (cMap As Map)
    Log("State Reset")
End Sub

Private Sub btnReset_Click
    cvGestureImage1.ResetState
End Sub

P.S. Download the aar file from : mvn repository and place it in the additional libraries
