It works, but I need communication between the runtime and the webpage through query strings, and with an iframe this doesn't seems possible.

I think I could workaround if C2 had actions to set the width and height of the canvas at runtime. Any chance this could be added someday in an upcoming release?

I need to embed my exported project into an HTML, more specifically inside a div tag with "Width=100%" and "Height=100%", in a way that C2 canvas behave like in crop mode, showing more layout as the div gets larger.

I tried editing the exported HTML and adding some custom javascript with no success. I'm not entirely sure of how C2 setup the project to resize it's canvas.

How can I achieve this without breaking my project?

All of this will be possible with WebGL shaders that are probably coming on the next release. Just wait a little more until the feature is implemented an ironed out.

I guess it will not be much difficult to create custom shaders, so expect lots of effects once the feature gets enough time to mature.
