Can someone help me optimize this prepress script?

//This is an automatic imposition script for printing
//It automatically calculates the number of horizontal and vertical imposition plates
//and covers the canvas, but the original script does not support masking objects.
//So I used a very dumb way to achieve masked objects by automatically creating outer borders for the objects and checking the box for stitching with content.
//But in practice this is very slow and laggy.
// Salty Fish 2022.5.24 Hope someone can help me.
// The following operation is creating the outer border
