Streamlined Text Search
Aspose.Slides for Android via Java 24.6 offers efficient text search capabilities to locate specific text within presentations using the ITextSearchOptions interface. This code example demonstrates the text handling and search feature usage.
Presentation presentation = new Presentation("pres.pptx");
try {
TextSearchOptions textSearchOptions = new TextSearchOptions();
textSearchOptions.setWholeWordsOnly(true);
presentation.replaceText("the", "***", textSearchOptions, null);
presentation.save("pres-out.pptx", SaveFormat.Pptx);
} finally {
if (presentation != null) presentation.dispose();
}

Master Text Highlighting
Highlight keywords or regular expressions with precision using the ITextFrame.HighlightText() and ITextFrame.HighlightRegex() methods added to this version of the Android presentation processing API. Similarly, you can also highlight text or Regex within your presentations using the newly introduced IPresentation.HighlightText() and IPresentation.HighlightRegex() methods.
In the code examples given below, we will check how to highlight text/keywords or regular expressions in a text frame, respectively.
Presentation presentation = new Presentation("pres.pptx");
try {
ITextFrame textFrame = ((AutoShape)presentation.getSlides().get_Item(0).getShapes().get_Item(0)).getTextFrame();
// highlighting all words 'important'
textFrame.highlightText("important", Color.BLUE);
TextSearchOptions textSearchOptions = new TextSearchOptions();
textSearchOptions.setWholeWordsOnly(true);
// highlighting all separate 'the' occurrences
textFrame.highlightText("the", Color.MAGENTA, textSearchOptions, null);
presentation.save("pres-out2.pptx", SaveFormat.Pptx);
} finally {
if (presentation != null) presentation.dispose();
}

Presentation presentation = new Presentation("pres.pptx");
try {
Pattern regex = Pattern.compile("\\b[^\\s]{10,}\\b");
// highlighting all words with 10 symbols or longer
((AutoShape)presentation.getSlides().get_Item(0).getShapes().get_Item(0)).getTextFrame().highlightRegex(regex, Color.BLUE, null);
presentation.save("SomePresentation-out.pptx", SaveFormat.Pptx);
} finally {
if (presentation != null) presentation.dispose();
}

Targeted Text Replacement
Seamlessly replace text or Regex (regular expressions) with desired alternatives using the ITextFrame.ReplaceText() and ITextFrame.ReplaceRegex() methods. Developers can replace text and regular expressions in their presentations as well, with the newly added IPresentation.ReplaceText() and IPresentation.ReplaceRegex() methods.
Check out the code samples shared below to learn how to replace text or Regex in presentations on the Android platform, resptively.
Presentation presentation = new Presentation("pres.pptx");
try {
TextSearchOptions textSearchOptions = new TextSearchOptions();
textSearchOptions.setWholeWordsOnly(true);
// Replace all separate 'the' occurrences with '***'
presentation.replaceText("the", "***", textSearchOptions, null);
presentation.save("SomePresentation-out2.pptx", SaveFormat.Pptx);
} finally {
if (presentation != null) presentation.dispose();
}

Presentation presentation = new Presentation("pres.pptx");
try {
Pattern regex = Pattern.compile("\\b[^\\s]{10,}\\b");
// Replace all words with 10 symbols or longer with '***'
presentation.replaceRegex(regex, "***", null);
presentation.save("SomePresentation-out.pptx", SaveFormat.Pptx);
} finally {
if (presentation != null) presentation.dispose();

Enriched Gradient Rendering
You can control the visual appearance of two-color gradients with the ISaveOption.GradientStyle property and experience PowerPoint-like rendering in your Android applications. Here is how to use this feature.
Presentation pres = new Presentation("pres.pptx");

RenderingOptions options = new RenderingOptions();
options.setGradientStyle(GradientStyle.PowerPointUI);
