[Laszlo-dev] SOLO Swf Resize while Preserving Aspect Ratio

[Aaron Shepherd]

The problem isn't with the embed.js, since I'm not actually using that.

The problem is with the SWF file that is generated through the Laszlo
compiler.  It must contain a setting for the scale option that is not
allowing for scaling while preserving the aspect ratio.

If I set the scale=showingall in the embed tag, set the width and height
on the embed tag to 100%, then I want the app to scale to the browser
width/height with aspect.  If you do this with a "normal" flash file,
like any of the example "working" swf files in the demos, it works the
way I want the Laszlo outputted swf files to work.

I'm sure there is a setting somewhere in the SWF writing classes (or
perhaps in the compiler source), that controls this functionality.

I just need to find the right 2 lines of code :)

Thanks,

Aaron

embed.js is very tricky to work with.  You could try ?lzt=html-object  
and look at the source to play with the plug-in options; or, maybe  
you just want to set the canvas width/height to 100%, which will  
cause it to size to the plug-in?
