I'm new to corona, but not new to Android development.
When developing natively, I would use "createScaledBitmap" to perform a high quality bitmap down-scaling to device-resolution and then cache the resulting bitmap for later runs so performance isn't impacted. This approach is recommended by google:
There was not a lot of information about the scaler used by Corona, but from very initial testing, it seems to be unfiltered bilinear, while I was hoping to reach Bicubic/Lanczos scaling quality.
My question is two-fold:
1. Is it possible to setup the scaler quality to use a better than default quality algorithm?
2. Can I access Android's "createScaledBitmap" from corona (there is also a comparable function in Windows)?
