Android Question ZoomImageView, image map and zoom factor

[Drago Bratko]

On this control I would need to have two additional options on it :
- image map
- possibility to create 'image maps' which would be polygon (or rectangle) area which would be then clickable
- or that click event would return x and y coordinate of clicked position
- zoom restriction
- that it would be definable to set max zoom and minimal zoom
- or that there is zoom event which would have 'zoom factor' property and cancel possibility by code

Is it possible that I do that or author (Erel) should do it (if he has time, of course) ?

You will need to add such features yourself. It is a b4xlib, so the code is inside the zip file.

OK, got it. Will try to do so. Thank you.

For Android my ScaleImageView does most of what you need. I wrote it for my map use and it supports click locations.

Thank you for your feedback. I appreciate it.
My app should on the end work on Android and iOS ... that's reason why I was thinking to base it on Erel's control which is cross platform.

B4J offline map app - jpg/jgw

I can not find the offline map app for B4J, therefore I make a little app for it. The app is not perfect but it is at least the beginning. Thank you "Erel", "oparra" and "emexes" for your advices here...
