What’s new in this release?

The long awaited version of Aspose.Slides for Java 14.9.0 . Aspose team has introduced support for replacing an image in a presentation image collection with a different one. As a result of this, the image is replaced in all instances in the presentation that refers to it. This release also introduced support for setting the fill format for SmartArt nodes and devlopers can now set the fill color or pattern for SmartArt nodes. More details about this feature are available in the article Setting Fill Format for SmartArt Node in the documentation section. Aspose team has introduced support for generating a PDF for a specific number of slides. Users can find more details by visiting and reading the article Exporting Presentation to PDF in the documentation section. Support for generating HTML files for individual presentation slides has also been included in this new release. Now, Aspose.Slides for Java makes it possible to get warning callbacks for font substitution in case the used font is not available on the machine during the rendering process. Warning callbacks are helpful when debugging issues of missing or inaccessible fonts during rendering. Developers can find more details about this feature by visiting the article Getting Warning Callbacks for Fonts Substitution in Aspose.Slides. Aspose team has rectified exception issues that appeared when accessing, saving and rendering presentation to PDF, HTML or slide thumbnails, which resulted in different exceptions like KeyNotFoundException, UnKnownFileFormatException, NullReference, ArgumentException, and IndexOutOfRange in previous releases. It has taken a leap towards improving the presentation rendering support for exported PDF, SVG, HTML and slide thumbnails in this release. Several issues pertaining to improper text, wrong shape, improper charts, unfitting SmartArt and wrong font rendering have been addressed in this regard.
