Abstract
A PDF document is repurposed to save paper and ink. Preprocessing is performed on the PDF document. The PDF document has a first quantity of pages of content and a first quantity of ink. Further, complexity analysis is performed on the PDF document. In addition, a document object model based on the PDF document is created. In addition, content re-layout is performed on the PDF document based on the content repurposing such that a printer prints the PDF document with the content in a transformed format that results in a second quantity of pages being printed without falling below a predetermined readability threshold and a second quantity of ink being utilized. The second quantity of pages is less than the first quantity of pages. The second quantity of ink is less than the first quantity of ink.
