I wrote 2 blog posts explaining how image data is stored in a PDF file at https://blog.idrsolutions.com/2010/04

The class is still mentioned in the documentation/tutorials on the Apache page. Any ideas? 回答1: The Lucene support was moved to a separate component within PDFBox (see PDFBOX-752). You can find it under the lucene directory in the PDFBox source tree or as the pdfbox-lucene artifact on the central Maven repository. And the jars can be downloaded from sites like

This question is in reference to a question asked here (Ref: https://github.com/dhorions/boxable/issues/89 ) In this, flurinBoonea presented a small sample code to put Text, Image and Table all in the same page. My question is, if I want to create a Table (which has dynamic height based on the content inside) and then I need to put some text after the table. How am I able to do that ?!? Somewhere I read that

问题 I have text annotation on my pdf but when I am converting pdf to image file using pdfbox api, annotation disappears(not visible on image). I have searched for couple of forums but I did not get accurate answer of this question. for (int page = 0; page < document.getNumberOfPages(); ++page) { BufferedImage bim = pdfRenderer.renderImageWithDPI(page,70,ImageType.RGB); // suffix in filename will be used as the file format ImageIOUtil.writeImage(bim, pdfFullPath + "-" + (page+1) + ".png", 70); }

问题 I am working with a large document, but I have extracted the page giving trouble here. The y-coordinates I get back for the lines in the table seem to be stretched beyond the coordinates of the text. There seems to be some transformation going on, but I cannot find it. If possible I would like to fix the problem within the scope of the PDFGraphicsStreamEngine as extended below, and not have to go back to the drawing board with the other input streams available in PDFBox. I have extended
