itext7

问题 I use iText 7 with html2pdf 2.1.2 version and try to convert HTML file to PDF. I use HtmlConverter#convertToElements to process an html file. Then I would like to calculate the width of one of the elements (a table in particular). I have tried to implement custom TagWorker class, but i get table only after it's filled.

问题 ColumnText ct = new ColumnText(writer.getDirectContent()); ct.setSimpleColumn(left,bottom,right,top); ct.setText(new Phrase("String")); ct.go(); This how we were doing in Itext 5 . But how can we place text on specific position on page . I have multiple text to place on page along with images . Thanks 回答1: Try this: Paragraph p = new Paragraph("test"); p.setFixedPosition(100, 800, 200); document.add(p); It should be that simple. In this example, x = 100, y = 800, and 200 is the width.

问题 This code below does not work. Table table = new Table(2); table.setBorder(Border.NO_BORDER); I am new to itext7 and all I wanted is to have my table borderless. Like how to do it? 回答1: The table itself is by default not responsible for borders in iText7, the cells are. You need to set every cell to be borderless if you want a borderless table (or set the outer cells to have no border on the edge if you still want inside borders). Cell cell = new Cell(); cell.add("contents go here"); cell

问题 I'm working on a rather complex solution that takes an html-like input and converts it to a pdf. One of the many items that I'm trying to solve for is adding barcodes (all types, 3 of 9, PDF417, and qr code) to the footer of documents. A couple details that give me pause on how to implement: Bar code will contain current page number Bar code will contain total page count Bar code will be inside other itext elements (like a table cell or paragraph) and (in the final solution) needs to be

问题 I'm using the Link and Destination tags of iText 7.0.5 to create the links while generating the pdf doc. When there is only one Link and Destination, its working as expected. But when I'm adding multiple links and destination, its not working as expected. For example there are three links and 3 destinations and each link mapped to different destination. If I click on third link in PDF it will be redirected to third destination, but if I click on first and second links, those are also
