How to change/crop to larger page size?

Question

Hi,
I have the following script to loop through each page in a document, check if each page is A4 Portrait size, and if it is, change it to US Letter paper size:
//Change Portrait A4 Page Size to US Letter Size
//Values are in points and there are 72 points per inch
//Check if page is Portrait A4 size (if Yes, then crop to US Letter otherwise ignore)
for (var i=0; i<this.numPages;i++){
var rCrop = this.getPageBox("Crop",i);
if (this.getPageBox("Crop",i)[1]<842 && getPageBox("Crop",i)[1]>841 && getPageBox("Crop",i)[2]<596 &&
getPageBox("Crop",i)[2]>595){
rCrop[0] -= 8.28; // Adjust Left Side
rCrop[1] -= 24.84; // Adjust Top Side
rCrop[2] += 8.28; // Adjust Right Side
rCrop[3] += 24.84; // Adjust Bottom Side
this.setPageBoxes("Crop",i,i,rCrop);
The script crops the top and bottom of each page correctly, but only expands the width of the left and right sides on the first page. After doing some experiments it seems the script will crop pages to a smaller size but struggles to expand pages to a larger size (in converting from A4 to US Letter I need to crop top and bottom to smaller size, but expand left and right sides to larger size). I tried changing "Crop" to "Media" but this didn't help.
Any ideas?
Many thanks. HJ

The page size options are limited, but are in the crop tool. If there are no tags or other markup, you can also print to a new PDF and adjust the size in the printer interface -- sometimes the simplest method, but not normally recommended. The rotation can be done in the document menu and then saved. The rotation that is typically on the toolbar are only for the current view and does not save with the PDF. Many of these you can use a batch process to resolve (in AA8 that is under the Advanced>Document Processing). The better method is to setup your Adobe PDF printer to create the correct page size and orientation in the future. You can setup to typically expand to fit, select a paper size, and have the settings set to auto-rotate. The later is based on the text that is found on the page. The margin elimination is also part of the crop tool. Hopefully this at least gives you some things to look at. Unfortunately, the tools get moved around with every version, so you may have to search for the tools.
