Extract Highlighted Text from PDF Document

This code snippet demonstrates how to extract only the highlighted text from a PDF document using Aspose.PDF for C++. By filtering text markup annotations, you can retrieve the specific text highlighted within a document.

void ExtractHighlightedText() {

    // Start logging
    std::clog << __func__ << ": Start" << std::endl;

    // Define the file paths
    String _dataDir("C:\\Samples\\Parsing\\");
    String infilename("sample-highlight.pdf");
    String outfilename("extracted-text.txt");

    // Open the PDF document
    auto document = MakeObject<Document>(_dataDir + infilename);

    // Loop through all annotations on the first page
    for (auto annotation : document->get_Pages()->idx_get(1)->get_Annotations())
    {
        // Check if the annotation is a highlight annotation
        if (annotation->get_AnnotationType() == Aspose::Pdf::Annotations::AnnotationType::Highlight)
        {
            // Cast annotation to HighlightAnnotation
            auto highlightedAnnotation = System::DynamicCast<Aspose::Pdf::Annotations::HighlightAnnotation>(annotation);

            // Retrieve the highlighted text fragments
            auto collection = highlightedAnnotation->GetMarkedTextFragments();
            
            // Loop through the text fragments and print the highlighted text
            for (auto tf : collection)
            {
                String s = tf->get_Text();
                std::cout << s << std::endl; // Display highlighted text
            }
        }
    }

    // Finish logging
    std::clog << __func__ << ": Finish" << std::endl;
}

Add Image to Existing PDF File

This example demonstrates how to add an image to an existing PDF file using operators in Aspose.PDF for C++. The operators manage the placement and drawing of the image on the PDF page.

void ExampleUsingOperators()
{
    // Define file paths
    String _dataDir("C:\\Samples\\");

    // Open the input PDF document
    auto document = MakeObject<Document>(_dataDir + u"PDFOperators.pdf");

    // Set coordinates for the image placement
    int lowerLeftX = 100;
    int lowerLeftY = 100;
    int upperRightX = 200;
    int upperRightY = 200;

    // Get the page where the image needs to be added
    auto page = document->get_Pages()->idx_get(1);

    // Load the image into a stream
    auto imageStream = System::IO::File::OpenRead(_dataDir + u"PDFOperators.jpg");

    // Add the image to the Resources collection of the page
    page->get_Resources()->get_Images()->Add(imageStream);

    // Save the current graphical state using GSave operator
    page->get_Contents()->Add(MakeObject<Aspose::Pdf::Operators::GSave>());

    // Create a Rectangle and Matrix object for the image placement
    auto rectangle = MakeObject<Rectangle>(lowerLeftX, lowerLeftY, upperRightX, upperRightY);
    auto matrix = MakeObject<Matrix>(
        new double[] {
            rectangle->get_URX() - rectangle->get_LLX(), 0, 0,
            rectangle->get_URY() - rectangle->get_LLY(),
            rectangle->get_LLX(),  rectangle->get_LLY() });

    // Use ConcatenateMatrix to define where the image should be placed
    page->get_Contents()->Add(MakeObject<Aspose::Pdf::Operators::ConcatenateMatrix>(matrix));

    // Use the Do operator to draw the image on the page
    auto ximage = page->get_Resources()->get_Images()->idx_get(page->get_Resources()->get_Images()->get_Count());
    page->get_Contents()->Add(MakeObject<Aspose::Pdf::Operators::Do>(ximage->get_Name()));

    // Restore the graphical state using GRestore operator
    page->get_Contents()->Add(MakeObject<Aspose::Pdf::Operators::GRestore>());

    // Save the updated document
    document->Save(_dataDir + u"PDFOperators_out.pdf");
}

Convert a PDF from RGB Colorspace to Grayscale

This code snippet shows how to convert a PDF document from RGB colorspace to grayscale using Aspose.PDF for C++. This can be useful for reducing the file size or preparing the PDF for printing.

void ConvertPDFfromColorspaceToGrayscale() {
    // Define file paths
    String _dataDir("C:\\Samples\\");
    String infilename("OptimizeDocument.pdf");
    String outfilename("Test-gray_out.pdf");

    // Open the PDF document
    auto document = MakeObject<Document>(_dataDir + infilename);

    // Create a grayscale conversion strategy
    auto strategy = MakeObject<Aspose::Pdf::RgbToDeviceGrayConversionStrategy>();

    // Iterate through all pages and apply the grayscale conversion strategy
    for (int idxPage = 1; idxPage <= document->get_Pages()->get_Count(); idxPage++)
    {
        auto page = document->get_Pages()->idx_get(idxPage); // Get the page
        strategy->Convert(page); // Convert the page to grayscale
    }

    // Save the resultant grayscale PDF file
    document->Save(_dataDir + outfilename);
}
