Add Arc Object to PDF file

Add Arc object

Aspose.PDF for C++ supports the feature to add graph objects (for example graph, line, rectangle etc.) to PDF documents. It also offers the feature to fill Arc object with a certain color.

Follow the steps below:

1. Create Document instance

2. Create Drawing object with certain dimensions

3. Set Border for Drawing object

4. Add Graph object to paragraphs collection of page

5. Save our PDF file

The following code snippet shows how to add a Arc object.

void ExampleArc() {
    // Create Document instance
    String _dataDir("C:\\Samples\\");
    // Create Document instance
    auto document = MakeObject<Document>();

    // Add page to pages collection of PDF file
    auto page = document->get_Pages()->Add();

    // Create Drawing object with certain dimensions
    auto graph = MakeObject<Aspose::Pdf::Drawing::Graph>(400, 400);
    // Set border for Drawing object
    auto borderInfo = MakeObject<BorderInfo>(BorderSide::All, Color::get_Green());
    graph->set_Border(borderInfo);

    auto arc1 = MakeObject<Aspose::Pdf::Drawing::Arc>(100, 100, 95, 0, 90);
    arc1->get_GraphInfo()->set_Color(Color::get_GreenYellow());
    graph->get_Shapes()->Add(arc1);

    auto arc2 = MakeObject<Aspose::Pdf::Drawing::Arc>(100, 100, 90, 70, 180);
    arc2->get_GraphInfo()->set_Color(Color::get_DarkBlue());
    graph->get_Shapes()->Add(arc2);

    auto arc3 = MakeObject<Aspose::Pdf::Drawing::Arc>(100, 100, 85, 120, 210);
    arc3->get_GraphInfo()->set_Color(Color::get_Red());
    graph->get_Shapes()->Add(arc3);

    // Add Graph object to paragraphs collection of page
    page->get_Paragraphs()->Add(graph);

    // Save PDF file
    document->Save(_dataDir + u"DrawingArc_out.pdf");

}

Create Filled Arc Object

Next example shows how to add a Arc object that is filled with color and certain dimensions.

void ExampleFilledArc() {

    // Create Document instance
    String _dataDir("C:\\Samples\\");
    // Create Document instance
    auto document = MakeObject<Document>();

    // Add page to pages collection of PDF file
    auto page = document->get_Pages()->Add();

    // Create Drawing object with certain dimensions
    auto graph = MakeObject<Aspose::Pdf::Drawing::Graph>(400, 400);
    // Set border for Drawing object
    auto borderInfo = MakeObject<BorderInfo>(BorderSide::All, Color::get_Green());
    graph->set_Border(borderInfo);

    auto arc = MakeObject<Aspose::Pdf::Drawing::Arc>(100, 100, 95, 0, 90);
    arc->get_GraphInfo()->set_FillColor(Color::get_GreenYellow());
    graph->get_Shapes()->Add(arc);

    auto line = MakeObject<Aspose::Pdf::Drawing::Line>(MakeArray<double>({ 195, 100, 100, 100, 100, 195 }));
    line->get_GraphInfo()->set_FillColor(Color::get_GreenYellow());
    graph->get_Shapes()->Add(line);

    // Add Graph object to paragraphs collection of page
    page->get_Paragraphs()->Add(graph);

    // Save PDF file
    document->Save(_dataDir + u"DrawingArc_out.pdf");

}

Let’s see the result of adding a filled Arс:
