pdfbox

My question is very simple: how can I center a text on a PDF, using PDFBox ? I don't know the string in advance, I can't find the middle by trial. The string doesn't always have the same width. I need either: A method that can center the text, something like addCenteredString(myString) A method that can give me the width of the string in pixels. I can then calculate the center, for I know the dimensions of the PDF. Any help is welcome! SteeveDroz 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

I'm using PDFbox to extract the coordinates of words/strings in a PDF document, and have so far had success determining the position of individual characters. this is the code thus far, from the PDFbox doc: package printtextlocations; import java.io.*; import org.apache.pdfbox.exceptions.InvalidPasswordException; import org.apache.pdfbox.pdmodel.PDDocument; import org.apache.pdfbox.pdmodel.PDPage; import org.apache.pdfbox.pdmodel.common.PDStream; import org.apache.pdfbox.util.PDFTextStripper; import org.apache.pdfbox.util.TextPosition; import java.io.IOException; import java.util.List; public

Link to example PDF: click here . Here you can see that many labels in the left are clipped (because of some clipping instructions) When I use PDFTextStripper, it prints all text which is actually cut/hidden in example PDF file. I have already tried solution described here however it makes it even worth because removes much text in the top + some text in the beginning of each row. Is there any other way to show only visible characters, and skip all overlapped, using PDFBox? Or maybe is there any other tool which could return only visible text? Thanks in advance. The reason why the

I am new to PDFBox and Boxable and I'm hoping if someone could help me with this! 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 while drawing the table I use something similar to get the YPosition for next element, float yPosition =

I am using Java PDFBox version 2.0. I want to know how to add a back ground image to the pdf. I can not find any good example in the pdfbox.apache.org Do this with each page, i.e. from 0 to doc.getNumberOfPages(): PDPage pdPage = doc.getPage(page); InputStream oldContentStream = pdPage.getContents(); byte[] ba = IOUtils.toByteArray(oldContentStream); oldContentStream.close(); // brings a warning because a content stream already exists PDPageContentStream newContentStream = new PDPageContentStream(doc, pdPage, false, true); // createFromFile is the easiest way with an image file // if you

As discussed in this question ( Wrap image to Jframe ), i need a jframe to match the exact provided image (The image itself is originally a PDF which has been converted to an image) The solution provided does indeed build a jframe to my image dimensions, but i can't actually see all of the image. I need to be able to resize the jframe, with the image dynamically adjusting to the new jframe size. Failing that, i think if i could just scroll the jframe or even zoom in or out, i could at least get to the parts of the image that i currently cannot see. The reason i need this is that, within my

I have a program that create TextFields inside a PDF-file so it can be used as a form. I would like to have the text I write in the TextFields I created to be centered though. How is that possible? My code currently looks like this: PDTextField textBox = new PDTextField(acroForm); textBox.setPartialName("Field " + j + " " + i); defaultAppearanceString = "/Helv 8 Tf 0 g"; //Textsize: 8 textBox.setDefaultAppearance(defaultAppearanceString); acroForm.getFields().add(textBox); PDAnnotationWidget widget = textBox.getWidgets().get(0); PDRectangle rect = new PDRectangle(inputField.getX(), inputField
