Add or Search Hidden Text in PDF Document & Change Annotations Orientation using Java

LANE COVE, Australia - June 13, 2016 - PRLog -- What's New in this Release?

Aspose team is pleased to announce the release of Aspose.Pdf for Java 11.4.0. In order to add hidden text, pass an argument of true to TextState.setInvisible(…) method. TextFragmentAbsorber finds all text that match pattern (if specified). Please note that hidden text in the document will be invisible for end user while viewing the document with PDF reading software (e.g. Acrobat Reader). But it can be found using text search. There are several ways to make text invisible for end user in PDF and we have implemented one of those techniques. However the text added through our approach can be found using TextFragmentAbsorber and we cannot guarantee that any hidden text added by third party applications can be found using same approach but in case you encounter any issue, please share the resource file and we can further investigate the scenario. The processParagraphs() method was introduced to calculate objects placed inside PDF file and in case we need to have page count information during PDF file generation, this method can be used as it manipulates file objects and returns the desired information. In earlier release versions, once this method was called, the file objects could not be accessed any further. So if you need to add any new object to existing page instance, it was not possible and you had to have a new Page instance where objects can be placed. Nevertheless, starting this new release, you can utilize same Page objects even after calling the processParagraphs() method. A new Rotate(...) method is added for annotation which provides the capabilities to change annotations orientation. As well as the enhancements and features discussed above, there have been specific improvements regarding Text extraction from PDF, image placement inside PDF, PDF to HTML, HTML to PDF, PDF to PDF/A, XPS to PDF, PDF to Image, PDF to TIFF, TIFF to PDF conversion and PDF printing are also improved.
