Starting with v2017R1, Qoppa Java PDF library jPDFProcess offers an API to easily resize or change page sizes in a PDF document.The resize options are as follow:Media Box – new media box for the PDF Page.Center – option to center the page contents in the new media box (off by default)Auto Scale – option to scale the page contents to fit inside the new media box (off by default)XOffset, YOffset – x and y offset of the page contents. If center or auto scale is on, then this value is not used.Scale – scale to be applied to the page content. Not used if auto scale is set to true.Rotation – amount to rotate the page contents in radians. A positive value rotates the page counter clockwise.Fit To Media – option to set the page’s crop box equal to the page’s media box, otherwise the crop box will have the same margins as before resizing. The default is off.Here is a Java sample program that will open a PDF and resize its pages to A3 format. Media Box and Crop Box will be resized to A3. The page content is re-scaled and centered to fit the new format.// Load documentPDFDocument pdfDoc = new PDFDocument("C:/qoppa/test/in.pdf", null); // Get the first page of the PDFPDFPage page = pdfDoc.getPage(0); // Create ResizePageOptions objectResizePageOptions options = new ResizePageOptions(); // Get the page size A3 (297mm x 420mm) in pointsdouble width = 297 / 25.4 * 72.0;double height = 420 / 25.4 * 72.0; // Set the new Media Boxoptions.setMediaBox(new Rectangle2D.Double(0, 0, width, height)); // Scale the page contents to fit the new page sizeoptions.setAutoScale(true); // Center the page contents on the pageoptions.setCenter(true); // Set the crop box to the same size as the media boxoptions.setFitToMedia(true); // Resize the pagepage.resizePage(options); // Save the output documentpdfDoc.saveDocument("C:/qoppa/test/out.pdf");Download the full Resize PDF Pages Java Sample.You can try the functionality in our end-user application PDF Studio, which makes it simple to visualize the different resize properties available.
