Android Question [B4X] HugeImageView: how to set starting point?

Alessandro71 · Feb 18, 2023

HugeImageView starts all zoomed out at the center of the image.
Is it possible to center a specific point in the image and set a zoom level?

Change the last line in SetBitmap to:

B4X:

ZoomChanged(pnl.Width / 2, pnl.Height / 2, 2)

This will set the image to be centered and with zoom level 2. You will need to do some math to zoom to a specific point.

The starting point will be different for each image, so I'll try to devise a "reverse geocoding"
