Image Rendering in PPTX, Enhanced Slide Animation Using Java

Question

What's New in this Release?

The long awaited version of Aspose.Slides for Java (14.7.0) has been released. This is a maintenance release whereby we have addressed several issues that have been reported recently. The main focus has been to improve issues with access and saving files as well as slide transitions and rendering issues. It introduced support for improved slide animations and transition effects in a presentation. It has also introduced support for cloning or serializing shapes within presentation slides. Now, it is possible to replicate shapes from a source slide by adding or inserting them into a target slide shape collection. Aspose team has rectified issues pertaining to presentation accessing and saving to other formats which resulted in exceptions like NullReference, ArgumentException, IndexOutOfRange, StackOverFlow, TextFrameFormat and unsupported format exception using older product versions. Aspose team has improved the API rendering performance in this release to a great extent in areas of charts, SmartArt, text and tables for generated slide thumbnails and exported PDFs. We have addressed several rendering issues for charts and text frames involving text spilling out of shape, improper chart titles, missing images, missing text and improper chart rendering issues for exported PDF and generated thumbnails. The SmartArt rendering has also been improved and issues like missing or improperly rendered SmartArt shape in exported PDFs have also been rectified. We have enhanced the rendering support in this release for chart entities, other text elements and shapes inside generated thumbnails and PDF files. It has made several enhancements to the new API.
