Android Question [ZoomImageView question] Automatically set image to a certain size and hide white background

[aironium]

I'm trying to remake the PDA from S.T.A.L.K.E.R. especially its map component. I used the ZoomImageView library and upon loading, the map image is displayed with a white background and on almost fit on the screen:

I tried loading the image with LoadBitmapResize, but yields the same result.

The aimed effect upon load of page (appear event) should end up like this:

(or basically fit the image to the edges of the ZoomImageView (and lock it as the maximum zoom out size) and do not show the white background).

Current Snippet Used:

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("page_map")
    mapZoomable.SetBitmap(LoadBitmap(File.DirAssets, "zone.png"))
End Sub

I assume there should be a different option for accomplishing the task, and I am currently looking for alternatives. I don't really know if ZoomImageView is the correct option in the first place.

ZoomImageView will need some non-trivial modifications to behave as you want it. Maybe go with a simpler solution and use ScrollView2D with a large ImageView: https://www.b4x.com/android/forum/threads/b4x-xui-sd-xuiscrollview2d.106438/#content

I guess that zooming is not critical for this.
