Comparing Comments in Two PDF Documents

document, such as an array of annotations. You may then compare and report any

information using customized algorithms. For example, the code below reports how many

annotations exist in the two documents:

var doc2 = app.openDoc("/C/secondDoc.pdf");

var annotsDoc1 = this.getAnnots();

var annotsDoc2 = doc2.getAnnots();

console.println("Doc 1: " + annotsDoc1.length + " annots.");

console.println("Doc 2: " + annotsDoc2.length + " annots.");
