File Details

Are you looking to process PowerPoint presentations in C++ applications on Linux? Look no further than Aspose.Slides for C++ 24.6. This release offers text highlighting and replacement within presentations, better handling of corrupted PPTX files, and much more.

Work with Text Highlighting and Patterns

Boost the visual appeal of your slides effortlessly by highlighting particular text or text patterns with and without regular expressions. The ITextFrame::HighlightText and ITextFrame::HighlightRegex methods added in the latest release allow highlighting specified text or text patterns 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>();

// 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);


Replacing Text and Text Patterns in Linux

Developers can also replace text with alternative content for efficient editing using the latest C++ presentations library version. 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>();

// 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);


Optimized Handling of Corrupted PPTX Files

Aspose.Slides for C++ 24.6 provides improved flexibility when loading the corrupt PPTX files on Linux, reducing errors and ensuring an enhanced development experience.

Utilize Aspose.Slides for .NET Features

Users can now integrate the enhancements made in Aspose.Slides for .NET into their C++ apps and work with a more comprehensive feature set.

Search Text With the ITextSearchOptions Interface

The newly added ITextSearchOptions interface in this C++ PowerPoint presentations API provides options for text search within presentations, slides, or TextFrame on the Linux platform. This sample code demonstrates the feature usage in C++:

auto presentation = System::MakeObject<Presentation>(u"pres.pptx");

auto textSearchOptions = System::MakeObject<TextSearchOptions>();

presentation->ReplaceText(u"the", u"***", textSearchOptions, nullptr);

presentation->Save(u"pres-out.pptx", Aspose::Slides::Export::SaveFormat::Pptx);


Retrieve Text Search Results Easily

A new IFindResultCallback interface introduced in Aspose.Slides for C++ 24.6 delivers a callback method for fetching search results while using text search functionalities. The following code example shows how to utilize this feature in C++:

class FindResultCallback : public Aspose::Slides::IFindResultCallback
    void FoundResult(System::SharedPtr<ITextFrame> textFrame, System::String oldText, System::String foundText, int32_t textPosition) override
        //Handling the results...

class Example
    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);
