max
A value between 0 and 1. This number dictates how much the image can shrink if its height exceeds the activation threshold. A value of 1 will shrink the image down to the threshold height.
For example, if we have a pageHeight of 400px and activationThreshold = 0.5, Images with a height over 200px will shrink. Setting maxShrinkFactor to 0.5 will shrink an image with a height of 280px to 240px
