Hello,
I am currently using the PdfWriter / PdfReader for merging existing Pdf
documents, the process that is discussed frequently on the list. This is
working fine for me, however 1 requirement that I have for my project
is, I have to fit all merged pages into a standard orientation
(Portrait) and page size (PageSize.LETTER). My question is, how does the
rotation value from PdfReader.getPageSizeWithRotation return value play
into this process. For example, I have 2 different Pdf's that I am
working with, descriptions are as follows:
1. PageSize is Letter. Orientation (in acrobat reader) is landscape.
getPageSizeWithRotation returns a rotation as 0. I interpret this
as the page was created to be landscape and due to this, the
rotation is set to 0. This scenario works works fine for me,
because I check to see if the width > height when determining if
page needs to be rotated.
2. A bit more complex. Pdf consists of 6 viewable pages spread across
2 "physical" pages. E.g. I open in Reader, I see the 6 different
pages, however opening Pdf in Photoshop (using MediaBox) I get the
2 "physical" pages. Photoshop opens the pages in the proper
orientation, however it appears as if getImportedPages is
returning a rotated value. The getPageSizeWithRotation returns a
rotation as 270, and the CropBox has a rotation of 0. However, the
CropBox's width/height values tells me the orientation reflects a
rotated value (width > height)
What I am trying to figure out, is if the getPageSizeWithRotation
().getRotation() value should be used in my algorithm to determine if I
should rotate the page, and if so, how to handle the CropBox's
width/height values, or if I should strictly use the if (width > height)
determination.
Any help on the subject would be greatly appreciated considering I have
been working on this issue for 5 days now.
Thanks,
Jordan S. Jones
