Scalegorithm calculates how to properly scale a child element within a parent when conventional CSS options fail. This is useful for image scaling and cross-domain iframe situations.
Features:
- Auto fit images in a container
- Simulate padding around image
- Recenter origin after scaling
- Limit upscaling to prevent pixalation
Instead of directly manipulating DOM elements using scaleChild(), you may also use the calc() function to calculate numerical results.
