Upgrade your macOS-powered C++ PowerPoint applications with Aspose.Slides for C++ 24.6. Incorporate features such as text highlighting and replacement within presentations, improved handling of corrupt PPTX files, and more into your C++ applications.
Text Highlighting in macOS
Augment the appearance of your slides smoothly by highlighting specific text and text patterns using text or regular expressions. The ITextFrame::HighlightText and ITextFrame::HighlightRegex methods introduced in the latest version support this functionality within a TextFrame. This code example showcases how text can be highlighted in a text frame:
auto presentation = System::MakeObject<Presentation>(u"pres.pptx");
// highlighting all words 'important'
(System::ExplicitCast<Aspose::Slides::AutoShape>(presentation->get_Slide(0)->get_Shape(0)))->get_TextFrame()->HighlightText(u"important", System::Drawing::Color::get_LightBlue());
auto textSearchOptions = System::MakeObject<TextSearchOptions>();
textSearchOptions->set_WholeWordsOnly(true);
// highlighting all separate 'the' occurrences
(System::ExplicitCast<Aspose::Slides::AutoShape>(presentation->get_Slide(0)->get_Shape(0)))->get_TextFrame()->HighlightText(u"the", System::Drawing::Color::get_Violet(), textSearchOptions, nullptr);
presentation->Save(u"pres-out2.pptx", Aspose::Slides::Export::SaveFormat::Pptx);

Similarly, the following coding sample explains how to highlight text using Regex (regular expression) in a text frame:
auto presentation = System::MakeObject<Presentation>(u"pres.pptx");
System::SharedPtr<System::Text::RegularExpressions::Regex> regex = System::MakeObject<System::Text::RegularExpressions::Regex>(u"\\b[^\\s]{10,}\\b");
// highlighting all words with 10 or more characters
(System::ExplicitCast<Aspose::Slides::AutoShape>(presentation->get_Slide(0)->get_Shape(0)))->get_TextFrame()->HighlightRegex(regex, System::Drawing::Color::get_Blue(), nullptr);
presentation->Save(u"SomePresentation-out.pptx", Aspose::Slides::Export::SaveFormat::Pptx);

Text Replacement Made Convenient
Replace text with alternative content for enhanced editing using this release of the C++ PowerPoint presentations library. Please check out the following code example, which illustrates how to replace text in C++:
auto presentation = System::MakeObject<Presentation>(u"pres.pptx");
auto textSearchOptions = System::MakeObject<TextSearchOptions>();
textSearchOptions->set_WholeWordsOnly(true);
// Replace all separate 'the' occurrences with '***'
(System::ExplicitCast<Aspose::Slides::AutoShape>(presentation->get_Slide(0)->get_Shape(0)))->get_TextFrame()->ReplaceText(u"the", u"***", textSearchOptions, nullptr);
presentation->Save(u"SomePresentation-out2.pptx", Aspose::Slides::Export::SaveFormat::Pptx);

Handle Corrupted PPTX Files Seamlessly
Aspose.Slides for C++ 24.6 brings extended flexibility when loading corrupted PPTX files on macOS, reducing errors and ascertaining an elevated development experience.
Integrate Aspose.Slides for .NET Features
You can now utilize the improvements made in Aspose.Slides for .NET in your C++ apps and get your hands on a more comprehensive feature set.
Find Text Using the ITextSearchOptions Interface
The ITextSearchOptions interface implemented in the C++ presentations library provides options for text search within presentations, slides, or TextFrame on the macOS platform. This sample code demonstrates the feature usage in C++:
auto presentation = System::MakeObject<Presentation>(u"pres.pptx");
auto textSearchOptions = System::MakeObject<TextSearchOptions>();
textSearchOptions->set_WholeWordsOnly(true);
presentation->ReplaceText(u"the", u"***", textSearchOptions, nullptr);
presentation->Save(u"pres-out.pptx", Aspose::Slides::Export::SaveFormat::Pptx);

Easily Fetch Text Search Results
The newly added IFindResultCallback interface in Aspose.Slides for C++ 24.6 includes a callback method for retrieving search results when working with the text search functionality. The following code example shows how to utilize this feature in C++:
class FindResultCallback : public Aspose::Slides::IFindResultCallback
{
public:
void FoundResult(System::SharedPtr<ITextFrame> textFrame, System::String oldText, System::String foundText, int32_t textPosition) override
{
//Handling the results...
}
};
class Example
{
public:
void Execute()
{
System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"pres.pptx");
System::SharedPtr<FindResultCallback> callback = System::MakeObject<FindResultCallback>();
// Highlight all words "address".
pres->HighlightText(u"address", System::Drawing::Color::get_Yellow(), System::MakeObject<TextSearchOptions>(), callback);
pres->Save(u"pres-out.pptx", Aspose::Slides::Export::SaveFormat::Pptx);
}
};
