divideTextFrame.js

/////////////////////////////////////////////////////////////////
//Divide TextFrame v.2.2 -- CS and up
//>=--------------------------------------
// 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.
// New in 2.1 now right and center justification is kept.
// New in 2.2 better error checking, and now will run on more than one text frame at a time.
