Little help on map exploration project

Hi to all,

I made a little project to explore an ancient WWI battlefield with satellite photos.

Everything is ok with it but I'd like to add a zoom function with :

• zooming with touch on a tablet
• zooming with + and - buttons for desktop computer use
• keep the pictures within the screen (i.e. no blanks around it)
• constraint zooming within x1 and x0.3 (till photo fills screen)

Here's the link to the project :

thanks for any help !

Oh, and project online is here :

It says it needs the Boundary plugin.

I was going to copy the "Touch zoom" demo into an event sheet, and include it in your event sheet, and see if that worked.

You're right ! I used the Boundary plug in to constraint photos into the viewier.

Here's where you can get the plug in (very useful !) :

thanks for your help

Paradox the project was more about moving the images inside the viewport that making the viewport travel over the images. But I guess they are different approches

Any idea about that ?
