Convert PDF to Different Formats
Aspose.PDF for Java allows converting PDF to any of different supported formats like Word, HTML, PowerPoint, etc within Java applications is easy with just a few lines of code.
Save PDF in different formats - Java
// load the file to be converted Document pdoc = new Document(dir + "template.pdf"); // Convert to DOCX, HTML and PPTX pdoc.save(dir + "output.docx", SaveFormat.DocX); pdoc.save(dir + "output.pptx", SaveFormat.Pptx); pdoc.save(dir + "output.html", SaveFormat.Html);
Dynamically Manage PDF Files
Aspose.PDF for Java API not only creates files from scratch but also manipulates and saves documents to multiple formats including PDF/A compliant documents. Moreover, API also supports PDF generation from XML, PCL or image files.
Few of the files manipulation capabilities of API are table creation, specifying the table width, margin information, padding, row span, column-span, default cell text and much more. Nested tables, as well as the integration of tables with data sources, also supported.
Content Formatting on Most Granular Level
Java PDF library has the ability to align text horizontally as well as vertically. Within horizontal alignment, one can easily change content alignment from left to right with respect to languages such as Arabic, Hebrew, and Urdu and can handle white spaces in the text, set custom tab stops and much more. For vertical alignment, one can adjust text segments such as baseline or topline.
Furthermore, API supports defining text formatting for all segments of a document, changing text foreground and background colors and usage of replaceable symbols which allows changing the corresponding text content at runtime.
Protect PDF Files with Ease
API offers the facility to encrypt documents with a verity of encryption algorithms and key sizes. You may also set master and user passwords for further security. Content modification in documents such as content copying, printing, form field completion, degraded printing, annotation modification as well as PDF document assembly can all be restricted by using this library.
Encrypt PDF document - Java
// load file to be encrypted Document pfile = new Document(dir + "template.pdf"); // encrypt the document pfile.encrypt("userPassword", "ownerPassword", 0, CryptoAlgorithm.AESx256); // save the encrypted one pfile.save(dir + "output.pdf");
Enhance PDF Reports with Graphs & Images
Aspose.PDF for Java supports graphs, drawn on any page by specifying coordinates. You may also choose to rotate or scale the existing graphs to suit your requirements.
API allows images insertion, replacement, and deletion, present within files as well as enables to use images as watermark while creating files or manipulating existing documents.
Process PDF Form Fields
Beyond simple form fields processing like addition & removal of form fields, the library provides advanced features such as converting Dynamic XFA form to Standard AcroForm, getting form fields from a specific region of PDF document, adding tooltips and setting custom fonts for the form fields.
Adobe Acrobat Automation - Not Needed
Aspose.PDF for Java APIs are built using managed code that can be installed and deployed without needing Adobe Acrobat installed. It is easier and flexible to use as compared to Adobe Acrobat automation.
