Implementations may vary depending on the viewer that is used. Be prepared to spend an equal amount of time if that's what you want.ĭISCLAIMER: the UserUnit value isn't supported by all viewers. It took one of our customers several weeks to achieve this correctly. If you want to downscale pages, you can only use PdfWriter (which throws away all annotations) and you need to copy the annotations separately after transforming all the /Rect values of these annotations. Summarized: it's a piece of cake to rotate pages in an existing PDF, so is scaling the pages up to a bigger size. It looks like a page in landscape because the dimensions of the page are created in such a way that the width is greater than the height. You'll notice that this doesn't have any effect on page 4. In the example, I removed the key, changing all pages shown in landscape (of which the value for /Rotate is 90) into portrait (the default value for /Rotate is 0).
Version 1.7 of the PDF specification originally written by Adobe says: "Acrobat 7.0 supports a maximum UserUnit value of 75,000." Nothing is said about the minimum value, but experience tells us that the minimum value supported by Adobe Reader is 1, meaning you can't scale down.Īs for the rotation, you can change the rotation of a page by changing the /Rotate key in the page dictionary.

The ISO standard for PDF says that the range that can be used for the user unit is implementation-independent. If you change the UserUnit to 0.5, you'll see that it won't have any effect in Adobe Reader. We introduce a UserUnit of 2.5 for all pages that aren't scaled yet. Given an original PDF pages.pdf with rotated pages, cropped pages and annotations, we scale and rotate some pages, resulting in pages_altered.pdf. I've created a small ScaleRotate example that looks like this.

There is a PdfCopy.SetPagesize() function (which doesn't work, which I suspect means I'm doing it wrong), but I have basically no idea how to properly scale the source page when it needs to be resized.
#Is there a way to rotate pdf pages code#
I need some example code of using the PdfCopy class to resize a page.Preferably I'd like to continue using the PdfWriter class, but need it to copy/duplicate any visible annotations from the source pages and include them in the output, or.The problem I'm running into is that when using the writer class, it doesn't appear to be including the visible annotations from the source page (for instance: the comment are missing). To this end I'm using the PdfWriter class. Your document will now reflect the changes you have made.I'm using iTextSharp to import specific pages from a PDF, possibly rotate, resize or otherwise alter that page, and exporting it into a new PDF. Click OK when you have finished making your selections.
The selected page will become the new page 5 and the old page 5 will become page 4 in the new arrangement. For example, if you want to move page 1 to page 5, you enter a "5" in the Move To Page number field. All pages listed after the relocated page will shift backward a number. The relocated page will be inserted into the new arrangement at the number specified. When moving pages around, allow for document adjustments. Note: The Move to Page feature will move the selected page to the number indicated. Select the destination to save your selection.Within the Move Pages dialogue box that appears, use the radio buttons and controls provided to select an individual page or page range to move.Right-click in the PDF you wish to alter, and select " Move Pages." from the right-click menu.Using the Move Pages feature, pages may be moved to a different location within the PDF document. Click OK when you have finished making your selections to view the changes.Filter Page Selection and Orientation sections, choose which pages to rotate based on other criteria ( Even Pages or Odd pages Portrait Pages or Landscape Pages).Current Page (the default setting), All pages, or Pages within a range.Pages - rotate a range of pages and specify page numbers from: (starting page #) and to:(ending page #).Acrobat is different in that one can rotate individual pages using the page navigation panel and selecting the pages to process. There is no way to save this change in Reader. All - rotate all pages within the PDF document. In Adobe Reader DC there is an option under View to rotate all page in the PDF clockwise or counter clockwise.
