In this quick article, well focus on doing programmatic conversion between PDF files and other formats in Java. More specifically, well describe how to save PDFs as image files, such as PNG or JPEG, convert PDFs to Microsoft Word documents, export as an HTML, and extract the texts, by using multiple Java open source libraries. Maven Dependencies. The first library well look at is Pdf. Dom. Lets start with the Maven dependencies we need to add to our project lt dependency. Id org. apache. There are many interpretations to the internet for this web marketing or similar terms such as online marketing, internet marketing, emarketing and others. Id. lt artifact. Id pdfbox toolslt artifact. Id. lt version 2. I celebrate myself, and sing myself, And what I assume you shall assume, For every atom belonging to me as good belongs to you. I loafe and invite my soul. POI Apache Jakata java Microsoft Office ExcelWordPowerpoint API. Id net. sf. cssboxlt group. Id. lt artifact. Id pdf. Id. lt version 1. Were going to use the first dependency to load the selected PDF file. The second dependency is responsible for the conversion itself. The latest versions can be found here pdfbox tools and pdf. Whats more, well use i. Text to extract the text from a PDF file and POI to create the. Lets take a look at Maven dependencies that we need to include in our project lt dependency. Id com. itextpdflt group. Id. lt artifact. Id itextpdflt artifact. Id. lt version 5. Id com. itextpdf. Id. lt artifact. Id xmlworkerlt artifact. Id. lt version 5. Id org. apache. Id. Id poi ooxmllt artifact. Id. lt version 3. Id org. apache. Id. Id poi scratchpadlt artifact. Id. lt version 3. The latest version of i. Text can be found here and you can look for Apache POI here. PDF and HTML Conversions. To work with HTML files well use Pdf. Dom a PDF parser that converts the documents to an HTML DOM representation. The obtained DOM tree can then be then serialized to an HTML file or further processed. To convert PDF to HTML, we need to use XMLWorker, library that is provided by i. Text. 3. 1. PDF to HTMLLets have a look at a simple conversion from PDF to HTML private void generate. HTMLFrom. PDFString filename. PDDocument pdf PDDocument. Filefilename. Writer output new Print. Writersrcoutputpdf. PDFDom. Tree. write. Textpdf, output. In the code snippet above we load the PDF file, using the load API from PDFBox. With the PDF loaded, we use the parser to parse the file and write to output specified by java. Writer. Note that converting PDF to HTML is never a 1. The results depend on the complexity and the structure of the particular PDF file. HTML to PDFNow, lets have a look at conversion from HTML to PDF private static void generate. PDFFrom. HTMLString filename. Document document new Document. Pdf. Writer writer Pdf. Writer. get. Instancedocument. File. Output. Streamsrcoutputhtml. XMLWorker. Helper. Instance. parse. XHtmlwriter, document. File. Input. Streamfilename. Note that converting HTML to PDF, you need to ensure that HTML has all tags properly started and closed, otherwise the PDF will be not created. The positive aspect of this approach is that PDF will be created exactly the same as it was in HTML file. PDF to Image Conversions. There are many ways of converting PDF files to an image. One of the most popular solutions is named Apache PDFBox. This library is an open source Java tool for working with PDF documents. For image to PDF conversion, well use i. Text again. 4. 1. PDF to Image. To start converting PDFs to images, we need to use dependency mentioned in the previous section pdfbox tools. Lets take a look at the code example private void generate. Image. From. PDFString filename, String extension. PDDocument document PDDocument. Filefilename. PDFRenderer pdf. Renderer new PDFRendererdocument. Number. Of. Pages page. Buffered. Image bim pdf. Renderer. render. Image. With. DPI. Image. Type. RGB. Image. IOUtil. write. Image. bim, String. There are few important parts in the above mentioned code. We need to use PDFRenderer, in order to render PDF as a Buffered. Image. Also, each page of the PDF file needs to be rendered separately. Finally, we use Image. IOUtil, from Apache PDFBox Tools, to write an image, with the extension that we specify. Possible file formats are jpeg, jpg, gif, tiff or png. Note that Apache PDFBox is an advanced tool we can create our own PDF files from scratch, fill forms inside PDF file, sign andor encrypt the PDF file. Image to PDFLets take a look at the code example private static void generate. PDFFrom. ImageString filename, String extension. Document document new Document. String input filename. String output srcoutput extension. File. Output. Stream fos new File. Output. Streamoutput. Pdf. Writer writer Pdf. Writer. get. Instancedocument, fos. Image. get. Instancenew URLinput. Please note, that we can provide an image as a file, or load it from URL, as it is shown in the example above. Moreover, the extensions of the output file that we can use are jpeg, jpg, gif, tiff or png. PDF to Text Conversions. To extract the raw text out of a PDF file, well also use Apache PDFBox again. For text to PDF conversion, we are going to use i. Text. 5. 1. PDF to Text. We created a method named generate. Txt. From. PDF and divided it into three main parts loading of the PDF file, extraction of text, and final file creation. Lets start with loading part File f new Filefilename. String parsed. Text. PDFParser parser new PDFParsernew Random. Access. Filef, r. In order to read a PDF file, we use PDFParser, with an r read option. Moreover, we need to use the parser. PDF to be parsed as a stream and populated into the COSDocument object. Lets take a look at the extracting text part COSDocument cos. Doc parser. get. Document. PDFText. Stripper pdf. Stripper new PDFText. Stripper. PDDocument pd. Doc new PDDocumentcos. Doc. parsed. Text pdf. Stripper. get. Textpd. Doc In the first line, well save COSDocument inside the cos. Doc variable. It will be then used to construct PDocument, which is the in memory representation of the PDF document. Finally, we will use PDFText. Stripper to return the raw text of a document. After all of those operations, well need to use close method to close all the used streams. In the last part, well save text into the newly created file using the simple Java Print. Writer Print. Writer pw new Print. Writersrcoutputpdf. Text. pw. close Please note that you cannot preserve formatting in a plain text file because it contains text only. Text to PDFConverting text files to PDF is bit tricky. In order to maintain the file formatting, youll need to apply additional rules. In the following example, we are not taking into consideration the formatting of the file. First, we need to define the size of the PDF file, version and output file. Lets have a look at the code example Document pdf. Doc new DocumentPage. Size. A4. Pdf. Writer. Instancepdf. Doc, new File. Output. Streamsrcoutputtxt. Pdf. VersionPdf. Writer. PDFVERSION17. Doc. In the next step, well define the font and also the command that is used to generate new paragraph Font myfont new Font. StyleFont. NORMAL. Size1. 1. pdf. Doc. Paragraphn Finally, we are going to add paragraphs into newly created PDF file Buffered. Shoulder Workout Program List on this page. Reader br new Buffered. Readernew File. Readerfilename. String str. Line. Line br. read. Line null. Paragraph para new Paragraphstr. Line n, myfont. AlignmentElement.
