.NET developers can integrate refined text search features and highlighting capabilities into their presentation processing C# apps with Aspose.Slides for .NET 24.6 release (DLLs-only).

Streamlined Text Search

Seamlessly locate specific text within your C# presentations with the new ITextSearchOptions interface added to this release. With this update, you can control aspects like whole word matches for precise searching, as showcased in the following C# code sample:

using (Presentation presentation = new Presentation("pres.pptx"))
{
    presentation.ReplaceText("the", "***", new TextSearchOptions() {WholeWordsOnly = true}, null);
    presentation.Save("pres-out.pptx", SaveFormat.Pptx);
}

Enhanced Highlighting

You can achieve refined highlighting effects with the introduction of ITextFrame.HighlightText and ITextFrame.HighlightRegex methods in this version of Aspose.Slides for .NET. You can now target specific text or leverage regular expressions for enhanced highlighting. To learn how to highlight text in text frames, please refer to this code example:

using (Presentation presentation = new Presentation("pres.pptx"))
{
    // highlighting all words 'important'
    ((AutoShape)presentation.Slides[0].Shapes[0]).TextFrame.HighlightText("important", Color.LightBlue);
    // highlighting all separate 'the' occurrences
    ((AutoShape)presentation.Slides[0].Shapes[0]).TextFrame.HighlightText("the", Color.Violet, new TextSearchOptions()
        { WholeWordsOnly = true }, null);
    presentation.Save("pres-out2.pptx", SaveFormat.Pptx);
}

Powerful Text Replacement

With the introduction of ITextFrame.ReplaceText and ITextFrame.ReplaceRegex methods in the latest C# presentation API release, we have empowered developers to efficiently replace text using regular expressions or whole word matching. Please check out the following code example, which demonstrates replacing text with the help of a regular expression:

/using (Presentation presentation = new Presentation("pres.pptx"))
{
    Regex regex = new Regex(@"\b[^\s]{5,}\b");
    // Replace all words with 10 or more characters with '***'
    ((AutoShape)presentation.Slides[0].Shapes[0]).TextFrame.ReplaceRegex(regex, "***", null);
    presentation.Save("SomePresentation-out.pptx", SaveFormat.Pptx);
}

Control Gradients Easily

Aspose.Slides for .NET introduces a new ISaveOption.GradientStyle property in this release, which offers control over the visual rendering of two-color gradients when exporting presentations to images, as shown in this C# code sample:

using (Presentation pres = new Presentation("pres.pptx"))
{
    RenderingOptions options = new RenderingOptions();
    options.GradientStyle = GradientStyle.PowerPointUI;
    IImage img = pres.Slides[0].GetImage(options, 2f, 2f);
}
