G Giuliano Cucchiarini Member Licensed User Longtime User Dec 20, 2014 #1 Hi How can I Zoom an ImageView using the pinch gesture? I did this in B4a using the TouchImageView library, but there is no similar library in B4i. Do you have an alternative or another way? Thank You Giuliano C.

I inakigarm Well-Known Member Licensed User Longtime User Dec 21, 2014 #3 Seems that it's possible implementing pinch zoom with an image view inside scrollview , but don't know if this is accesible from B4i directly or via nativeobject. https://developer.apple.com/library...IScrollView_pg/Introduction/Introduction.html Another option as Erel said should be webview (there're some js clases here, like hammer.js) http://www.queness.com/post/11755/11-multi-touch-and-touch-events-javascript-libraries Upvote 0

As an alternative for small images, you can convert the image to base 64 string and then embed it in a html string: http://stackoverflow.com/questions/1207190/embedding-base64-images Upvote 0
