sbweb-scalegorithm v1.1.0

Scalegorithm

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

Scale math

Instead of directly manipulating DOM elements using scaleChild(), you may also use the calc() function to calculate numerical results.
