Shape Image Threshold
Overview
The shape-image-threshold CSS property sets the alpha channel threshold used to extract the shape using an image as the value for shape-outside.
<div class="">The shape-image-threshold CSS property sets the alpha channel threshold used to extract the shape using an image as the value for shape-outside.
Any pixels whose alpha component's value is greater than the threshold are considered to be part of the shape for the purposes of determining its boundaries.
For example, a value of 0.5 means that the shape will enclose all the pixels that are more than 50% opaque.
