What’s new in this release?

We are pleased to announce the release of Aspose.Pdf for Java 11.2.0 . We are pleased to announce that this new version not only includes all the features and enhancements introduced in Aspose.Pdf for .NET 11.2.0 but also contains the feature to change PDF document colorspace from RGB to Grayscale and set background image of submit button. It also includes some important bug fixes along with above stated enhancements. We received a requirement to convert a PDF document colorspace from RGB to Gray-scale, so that it would be faster while printing those PDF files. Also when file is converted to Grayscale, the size of document is reduced but with this change, the quality of document may drop. The feature is already supported in Aspose.Pdf for .NET version and now it is also supported in Java version of Aspose.Pdf. One of the customers wants to set the background image for submit button over form. We can set background image of submit button by using addImage() method in DOM approach. The other most notable enhancements in this release includes adding Grouped ChekBoxes, converting XML file to PDF, How to add transparent text in PDF and adding drawing with transparent Color.
