Aspose team is pleased to announce the release of Aspose.PDF for Java and .NET 18.11. In this revision of the API, conversion engines have been further improved in order to convert PDF documents into other file formats. Several bugs which were reported in earlier version(s) of the API have also been rectified. Along with that, resource optimization of PDF documents has been improved in terms of performance. It was observed that execution time of OptimizeResources method was slow in earlier version(s) of the API which was due to slow image compression. In this release of the API, new image compression algorithms have been implemented which work faster and users can optimize PDF documents in an improved and faster way. The sample code snippet on blog announcement page can be used to optimize PDF resources using new implemented properties. Along with the features mentioned above, there are some useful improvement also included in this release of the API, such as implemented precise coordinate calculations for characters, Improvements have been made for working with Form Fields, Hyperlink Alignment issues have been rectified, Improved PDF Printing time taken by the API, Color corrections have been made during PDF to TIFF conversion, Table Extraction and Manipulation algorithms have further been enhanced, Functionality to support text and fonts has been added for PDF/UA format and many more.
