Acrobat document resizing

[JKuruvilla]

Hello,

I want to use an applescript to resize my acrobat document (JavaScript also will do). Note that, this is not crop. My current document size is 7.5 inch x 10 inch and I want to make it 8.5 inch x 11 inch. This function available in crop tool (Set Page Boxes/Change Page size/Custom) if I want to do manually. Any help please?

With JavaScript you'd use the setPagesBoxes method to first set the media box to the size you want and then set the crop box to match.

Can you please give me little more insight on this?

[George_Johnson]

Exactly how do you want to go from 7.5 x 10 to 8.5 x 11? It might be by adding an inch to the right side, or 1/2 inch to both the left and right sides. Same thing for the top and bottom.

Also, do you want to do this for every page in the document, or just certain ones?

[JKuruvilla]

Thanks George for your feed back. I know how to do this manually, I have a bunch of PDFs with single pages. I am trying to find out an automated system such as applescript or JavaScript for the ongoing solution.

[George_Johnson]

Yes, I'm willing to show you how, but it would be helpful if you provided the information I asked about. The details are important.

[JKuruvilla]

Yes. It is single page document. I want to add 1/2 inch each on all four sides. meaning currently, it is 7.5x10 inches and want to get it as 8.5x11. thanks again.

Here's a basic script that should help you get started. It adds 1/2 inch to all sides of the page and assumes the page isn't rotated.

// Get the rect (left, top, right, bottom) for the media box of the current page

var aRect = getPageBox({cBox: "Media", nPage: 0});

// Set the  increment value, in points (72 points/inch)

var inc = 0.5 * 72;

// Set a new media box

setPageBoxes({cBox: "Media", nStart: 0, nEnd: numPages - 1, rBox: [aRect[0] - inc, aRect[1] + inc, aRect[2] + inc, aRect[3] - inc]});

You can run this script in the interactive JavaScript console (command + J), in a custom action, custom toolbar or menu item, etc. Post again if you need more help and consulting the Acrobat JavaScript reference is always a good idea.

Thanks George, I think I am very close. I am getting the following error.

When you execute it in the console, you have to select all of it and press command+return.

Thanks George. This works Good. One more question. How can I put this in loop? so that, I can select a bunch of PDFs, run at one time. Probably, an external script? how that will work?

[George_Johnson]

That what custom Actions are for. You can set one up with a single JavaScript action and process the files you select when you trigger the action. You should be able to find more information on creating and using Action in Acrobat with a search.
