iOS Question zoom in/out image

f0raster0 · May 19, 2016

I would like to show an Image in ImageView or similar,

What do I have to do to be able to zoom in/out the Image with 2 fingers?

Thank you all,

The simplest way is with WebView:

B4X:

WebView1.LoadUrl(File.Combine(File.DirAssets, "IMG_0001.PNG".ToLowerCase)) 'ToLowerCase is only required if the image is loaded from the assets folder.

Make sure that the ScaleToFit option is checked.

With the code I posted in post #2.

Bitmap is not in my DirAssets, its a bitmap variable in the code (some downloaded data)

You will need to write it to a temporary file:

B4X:

Dim out As OutputStream = File.OpenOutput(File.DirTemp, "temp.png", False)
bmp.WriteToStream(out, 100, "PNG")
out.Close
