StageWebView.drawViewPortToBitmapdata is resizing. :(

Hi,

I've built a stage web view component that draws and maintains stage webview. For animations etc. I transpose into a bitmap.

This works fine in theory, but on my Nexus7, I am finding that the whole thing displays about fifty percent too big!

EG: Using the code below, I get traces like this:

BUILT WITH (x=0, y=60, w=1280, h=643)

/// Stuff in the middle as animation proceeds

SCALES: (x=0, y=0, w=1280, h=703)

          (x=0, y=60, w=1920, h=964.5)

As you can see, the bitmap data is created at the correct dimensions, but as soon as I display it, it seems to resize from 1280x643 to 1920x964.5...

This, I hasten to add, looks naff.

Has anybody else encountered this and has anybody else got a workaround?

Thanks,

G
