The file which I have to merge with 1st file is in byte array

问题 Using Apache PDFBox, I am editing an existing document and I would like to take one page from that document and simply clone it, copying whatever elements it contains. As an additional twist, I would like to get a reference to all the PDField s for any form fields in this newly cloned page. Here's the code I tried so far: PDPage newPage = new PDPage(lastPage.getCOSDictionary()); PDFCloneUtility cloner = new PDFCloneUtility(pdfDoc); pdfDoc.addPage(newPage); cloner.cloneMerge(lastPage, newPage)

Displaying embedded fonts with PDFBox and Swing

由 微笑、不失礼 提交于 2019-12-07 02:33:28
I am using PDFBox to display PDF files inside a JInternalFrame. When opening PDF I get lots of warnings like this: Changing font on <m> from <Tahoma Negrita> to the default font I am aware that the fonts being reported are not part of the standard set of 14 fonts. So I decided to check if those fonts are embedded on the PDF file (thinking that there shouldn't be a problem loading embedded fonts, right?). So I open the file on different readers and check properties/fonts. I am in doubt whether this section reports fonts required by the document or fonts actually embedded in the document. The

How do I rotate the contents of a PDF page to an arbitrary angle?

由 烂漫一生 提交于 2019-12-06 14:06:42
问题 I need to rotate the contents of a PDF page by an arbitrary angle and the PDPage.setRotation(int) command is restricted to multiples of 90 degrees. The contents of the page are vector and text and I need to be able to zoom in on the contents later, which means that I cannot convert the page to an image because of the loss of resolution. 回答1: In comments it already has been indicated that to draw some content, e.g. an existing regular portrait or landscape page, at an arbitrary angle onto a

问题 I have just passed from PdfBox 1.8 to 2.0.0 and there are quite significant differences. Before to write a text on an existing pdf page I used drawString. In 2.0.0 draw string is deprecated but showText does not work in a block text. My code in 1.8: contentStream.beginText() contentStream.moveTextPositionByAmount(250, 665) contentStream.drawString("1 2 3 4 5 6 7 8 9 1 0") contentStream.endText() My code in 2.0 PDDocument newPdf=null newPdf=PDDocument.load(sourcePdfFile) PDPage firstPage
