Your approach When I pass a Tf operator that has a size greater than my threshold, don’t add the next Tj/TJ that is seen. is too simple. On one hand, as you remark yourself, the text may be scaled by the current transformation matrix. (Actually not only by the transformation matrix but also by the … Read more
Is it possible to use pdfbox to include other pdf pages as embedded objects within a page It should be possible. The PDF format allows the use of so called form xobjects to serve as such embedded objects. I don’t see an explicit implementation for that, though, but the procedure is similar enough to what … Read more
This answer is actually an explanation why a generic solution for your task is at least very complicated if not impossible. Under benign circumstances, i.e. for PDFs subject to specific restrictions, code like yours can be successfully used, but your example PDF shows that the PDFs you apparently want to manipulate are not restricted like … Read more
Adding to the answer of Mark you might want to know where to split your long string. You can use the PDFont method getStringWidth for that. Putting everything together you get something like this (with minor differences depending on the PDFBox version): PDFBox 1.8.x PDDocument doc = null; try { doc = new PDDocument(); PDPage … Read more
Extending PageDrawer didn’t really work, so I extended PDFGraphicsStreamEngine and here’s the result. I do some of the stuff that is done in PageDrawer. To collect lines, either evaluate the shape in strokePath(), or collect points and lines in the other methods where I have included a println. public class LineCatcher extends PDFGraphicsStreamEngine { private … Read more
Here’s some code to add a ToUnicode CMap stream in a font. Obviously I can’t do it with your file, so I used one of my test files, which can be found here. I had to work on each entry separately and didn’t do all. However the result is good enough to extract the first … Read more
Why not use the PDFMergerUtility of pdfbox? PDFMergerUtility ut = new PDFMergerUtility(); ut.addSource(…); ut.addSource(…); ut.addSource(…); ut.setDestinationFileName(…); ut.mergeDocuments();
Solution for 1.8.* versions: PDDocument document = PDDocument.loadNonSeq(new File(pdfFilename), null); List<PDPage> pdPages = document.getDocumentCatalog().getAllPages(); int page = 0; for (PDPage pdPage : pdPages) { ++page; BufferedImage bim = pdPage.convertToImage(BufferedImage.TYPE_INT_RGB, 300); ImageIOUtil.writeImage(bim, pdfFilename + “-” + page + “.png”, 300); } document.close(); Don’t forget to read the 1.8 dependencies page before doing your build. Solution for … Read more
