AI脚本分割文本框教程 脚本的作用

/////////////////////////////////////////////////////////////////
//Divide TextFrame v.2 -- CS,CS2
//>=--------------------------------------
// Divides a multiline text field into separate textFrame objects.
// Basically, each line in the selected text object
// becomes it's own textFrame. Vertical Spacing of each new line is based on leading.
//
// This is the opposite of my "Join TextFrames" scripts which
// takes multiple lines and stitchs them back together into the same object.
