Use for Font FallBack and Prompt Text using Aspose.Slides for .NET and Java

Hello readers! I am grateful to share the release announcement for v19.10 of Aspose.Slides for .NET and Java. We have included the support for exciting new features, which include support for using Font FallBack and Prompt Text setting inside presentation files generated using Aspose.Slides.

Support For Font FallBack

Almost for all symbols of Unicode characters, a reserve typeface is used that we can call Font Fallback. If any Unicode character is used in any application by selecting a particular font and that character is not part of the repertoire of used font, then, in this case, a symbol from Fallback font is used as a replacement for rendering. Aspose.Slides now offers the same support in API.

In the following code example, we have demonstrated the use of setting Font Fallback using FontFallBackRule objects.

The equivalent Java based example for this is:

Set Prompt Text in a Placeholder

When working with PowerPoint placeholders for text, the text field highlights what is to be entered in that. This phenomenon is called support for Prompt Text for a placeholder in PowerPoint. Prompt Text is only information string and vanishes as soon as you start writing your custom text to the placeholder. For example, you can observe Prompt Text fields like Click to add a title or Click to add subtitle when working with PowerPoint slides. Using Aspose.Slides you can now add custom Prompt Text manually by accessing the default placeholders.

In the following example, we have demonstrated the use of this new feature:

The Java-based implemented for this is as under:

Moreover, there are many other new features, enhancement, and bug fixes included in this release.
