You should use the iXUI library.
Declare both views as B4XView.
Private MyImageView, MyPanel As B4XView
Then use:
MyImageView.SetBitmap(MyPanel.Snapshot)

Tested with B4J, but it should work with B4i and B4A.

Thank @klaus it works but the image got distorted after Clicking Save Button and please, how do i save and share on other platforms

 

[klaus]

Snapshot returns a B4XBitmap.
With B4XBitmap.WriteToStream you can save it in a file.
Then, I have no experiene in sharing files between iOS and other platforms.
For the image distortion I suppose that the width / height ratio is not the same.

With B4XBitmap.WriteToStream you can save it in a file.

Thanks so much for the help but a little help on how to save

I have

Private MyImageView, MyPanel As B4XView

Sub Save_Click
    MyImageView.SetBitmap(MyPanel.Snapshot)
    Dim bmp As B4XBitmap = Panel5.Snapshot
    Dim Out As OutputStream
    Out = File.OpenOutput(File.DirDocuments,"1.jpeg", False)
    bmp.WriteToStream(Out, 100, "JPEG")
    Out.Close
End Sub

i still can't save the images let alone to share

please help me out with example

thanks

I already told you:
I have no experiene in sharing files between iOS and other platforms.
I would have to do the same as you could do: serch in the forum.
Erel gave you a link in post #5

Kindly help me out with how to save using b4xBitmap.writetostream. I have tried but could not get it working #6
Thank You

Your code correctly saves the bitmap. What is the problem?

Have sorted it out

the problem was with the Arrangement of the views in the Designer.

Thanks @Erel and @klaus
