Hi, I am new to illustrator and do not know about its tools' name. So, I want to change these attributes(underlined in red color shown in the picture) through ExtendScripting. Just let me know their abbreviation of VA, AA, etc or their functions in Extendscript.
To build @Joonas' comment into an answer, these two attributes are called (top to bottom) Leading and Tracking. As @Billy Kerr mentioned you can find these names by hovering over the icons. In ExtendScript their names are - reassuringly -
Here's example of them in action taken from the CS4 Scripting Guide (page 84, 86).
// Create & Get Text Object var myDocument = app.documents.item(0); var myPage = myDocument.pages.item(0); var myTextFrame = myPage.textFrames.add(); myTextFrame.contents = "x"; var myTextObject = myTextFrame.parentStory.characters.item(0); // Set Leading and Tracking myTextObject.leading = 12; myTextObject.tracking = 0;
I find the scripting guide can be quite useful. I'm new to ExtendScript and one method I've found is to search for the attribute name in the Scripting Guide, find examples of the attributes being used, and build my code from those examples.
