Android Question Square png image -> Shown as rounded corners image

I have scoured a lot of threads to determine how to do this; that is, a visible square image to a visible rounded corner image; however, I cannot seem to be able to find a solution.

I have several squared cornered png images that I would like to be seen (visible) with rounded corners.

I can do it with colours and gradients on panels and labels but I cannot take a square image and end up with a rounded corner image in a panel for example.

Any help would be appreciated.

Thank you.

The easiest way is to use my BetterImageView library with two images: one for the mask (same color as the background on the edges, with a transparent middle, shaped with round corners) and placed in the foreground. Another for the image to show through the mask, placed in the background. You can also do that by superposing two ImageViews.
An alternative is to use my Accelerated Surface library. There's an example showing an image with rounded corners.

I am not certain exactly how the rx and ry arguments work in the subroutine.

Sub Globals
    Dim cvsActivity As Canvas
    Dim ABExtDraw As ABExtDrawing
    Dim ABRect As ABRectF
    Dim ABPaint1 As ABPaint
End Sub

Sub Activity_Create(FirstTime As Boolean)
    cvsActivity.Initialize(Activity)
    ABPaint1.Initialize
    ABPaint1.SetStrokeWidth(3dip)
    ABPaint1.SetColor(Colors.Red)
    ABRect.Initialize(10dip, 10dip, 200dip, 100dip)
    ABExtDraw.drawRoundRect(cvsActivity, ABRect, 20dip, 20dip, ABPaint1)
  
    ABRect.Initialize(10dip, 110dip, 200dip, 200dip)
    ABExtDraw.drawRoundRect(cvsActivity, ABRect, 20dip, 10dip, ABPaint1)
  
    ABRect.Initialize(10dip, 210dip, 60dip, 260dip)
    ABExtDraw.drawRoundRect(cvsActivity, ABRect, 25dip, 25dip, ABPaint1)
  
    ABRect.Initialize(100dip, 210dip, 200dip, 260dip)
    ABExtDraw.drawRoundRect(cvsActivity, ABRect, 50dip, 25dip, ABPaint1)
End Sub
