Public API Changes

ITextSearchOptions interface has been added

The new interface, ITextSearchOptions, represents options that can be used to search for text in a Presentation, Slide or TextFrame.

Example:

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);

IFindResultCallback interface has been added

The new interface IFindResultCallback contains a callback method that can be used to retrieve search results.

Example:

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);
    }
};

ITextFrame::HighlightText() and ITextFrame::HighlightRegex() methods have been added

New methods HighlightText() and HighlightRegex() have been added to the ITextFrame interface and the TextFrame class.

The following code sample shows how to highlight text in a TextFrame:

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);

The following code sample shows how to highlight text using regular expression in a TextFrame:

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);

ITextFrame::ReplaceText() and ITextFrame::ReplaceRegex() methods have been added

New methods ITextFrame::HighlightText() and ITextFrame::HighlightRegex() have been added to the ITextFrame interface and the TextFrame class.

The following code sample shows how to replace a specified string with another specified string:

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);

The following code sample shows how to replace text using regular expressions:

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

System::SharedPtr<System::Text::RegularExpressions::Regex> regex = System::MakeObject<System::Text::RegularExpressions::Regex>(u"\\b[^\\s]{5,}\\b");

// Replace all words with 10 or more characters with '***'
(System::ExplicitCast<Aspose::Slides::AutoShape>(presentation->get_Slide(0)->get_Shape(0)))->get_TextFrame()->ReplaceRegex(regex, u"***", nullptr);

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

IPresentation::HighlightText() and IPresentation::HighlightRegex() have been added

New methods HighlightText() and HighlightRegex() have been added to the IPresentation interface and the Presentation class.

The following code sample shows to highlight text in a PowerPoint Presentation:

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

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

// highlighting all separate 'the' occurrences
presentation->HighlightText(u"the", System::Drawing::Color::get_Violet(), textSearchOptions, nullptr);

// highlight all 'abi' character sequences
presentation->HighlightText(u"abi", System::Drawing::Color::get_Red());

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

The following code sample shows how to highlight text using regular expressions:

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
presentation->HighlightRegex(regex, System::Drawing::Color::get_Blue(), nullptr);

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

IPresentation::ReplaceText() and IPresentation::ReplaceRegex() methods have been added

New methods ReplaceText() and ReplaceRegex() have been added to the IPresentation interface and the Presentation class.

The following code sample shows how to replace a specified string with another specified string:

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

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

// Replace all separate 'the' occurrences with '***'
presentation->ReplaceText(u"the", u"***", textSearchOptions, nullptr);

presentation->Save(u"SomePresentation-out2.pptx", Aspose::Slides::Export::SaveFormat::Pptx);

The following code sample shows how to highlight text using regular expressions:

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

System::SharedPtr<System::Text::RegularExpressions::Regex> regex = System::MakeObject<System::Text::RegularExpressions::Regex>(u"\\b[^\\s]{10,}\\b");

// Replace all words with 10 or more characters with '***'
presentation->ReplaceRegex(regex, u"***", nullptr);

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

ISaveOption::GradientStyle property has been added

A new property GradientStyle has been added to the ISaveOption interface and the SaveOption class. It allows users to change the visual rendering style of a two-color gradient. Two options are available:

GradientStyle::Default - renders the gradient similarly to how it appears when exporting a presentation to an image using PowerPoint.
GradientStyle::PowerPointUI - renders the two-color gradient according to its appearance in the PowerPoint user interface.

Example:

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

System::SharedPtr<RenderingOptions> options = System::MakeObject<RenderingOptions>();
options->set_GradientStyle(Aspose::Slides::GradientStyle::PowerPointUI);
System::SharedPtr<IImage> img = pres->get_Slide(0)->GetImage(options, 2.f, 2.f);
