I hope it’s not too late… ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(); document.save(byteArrayOutputStream); document.close(); InputStream inputStream = new ByteArrayInputStream(byteArrayOutputStream.toByteArray()); And voila! You’ve got both input streams!
Here is code using PDFBox 2.0.1 that will get a list of all images from the PDF. This is different than the other code in that it will recurse through the document instead of trying to get the images from the top level. public List<RenderedImage> getImagesFromPDF(PDDocument document) throws IOException { List<RenderedImage> images = new ArrayList<>(); … Read more
Using PDFBox 2.0.7, this is how I get the text of a PDF: static String getText(File pdfFile) throws IOException { PDDocument doc = PDDocument.load(pdfFile); return new PDFTextStripper().getText(doc); } Call it like this: try { String text = getText(new File(“/home/me/test.pdf”)); System.out.println(“Text in PDF: ” + text); } catch (IOException e) { e.printStackTrace(); } Since user oivemaria … Read more
Measurement units inside a PDF are in points, a traditional graphic industry measurement unit. Adobe uses the following definition: 1 pt = 1/72 inch and since one inch is defined to be exactly 25.4 mm (really!), you can convert from points to mm using the formula mm = pt*25.4 / 72 Your values, by the … Read more
Since I also needed table drawing functionality for a side project, I implemented a small “table drawer” library myself, which I uploaded to github. In order to produce such a table – for instance – … … you would need this code. In the same file you find the code for that table as well: … Read more
Here is what I have found out so far: PDFBox uses a resource file to bound PDF operators/instructions to certain classes which then process the information. If we take a look at the PDFTextStripper.properties resource file under: pdfbox\src\main\resources\org\apache\pdfbox\resources\ we can see that for instance the BT operator is bound to the org.apache.pdfbox.util.operator.BeginText class and so … Read more
Using pdfbox we can achive this Example : public static void main(String args[]) { PDFParser parser = null; PDDocument pdDoc = null; COSDocument cosDoc = null; PDFTextStripper pdfStripper; String parsedText; String fileName = “E:\\Files\\Small Files\\PDF\\JDBC.pdf”; File file = new File(fileName); try { parser = new PDFParser(new FileInputStream(file)); parser.parse(); cosDoc = parser.getDocument(); pdfStripper = new PDFTextStripper(); … Read more
Ok, I found the answer myself. Here is how to center some text on a page: String title = “This is my wonderful title!”; // Or whatever title you want. int marginTop = 30; // Or whatever margin you want. PDDocument document = new PDDocument(); PDPage page = new PDPage(); PDPageContentStream stream = new PDPageContentStream(document, … Read more
Inkscape can also be used to convert PDF to SVG. It’s actually remarkably good at this, and although the code that it generates is a bit bloated, at the very least, it doesn’t seem to have the particular issue that you are encountering in your program. I think it would be challenging to integrate it … Read more
