Currently only the Native platform supports the “Change camera size” action / function but is non-existent for the HTML5 platform.
This function is greatly needed for “responsive” apps that do not rely on a fixed size and instead adapt to the actual screen size of the device, providing a surely borderless result for all device / display resolutions without stretching or having “black” borders of any kind.
Reasoning and explanation: Camera size issue
If you plan to implement this and can give an estimate, could you provide an estimated time frame around which it is expected to appear as a new feature?
