Public API Changes

IPortion::GetRect() method has been added

IPortion::GetRect() method has been added. This method extends and actually replaces method IPortion::GetCoordinates(). IPortion::GetRect() and IParagraph::GetRect() methods can be applied to text within table cells.

The following example shows how those properties work. Let’s say we have a table with some text inside and simple AutoShape nearby.

todo:image_alt_text

The code snippet below generates those objects.

 {
    System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();

    System::SharedPtr<ITable> tbl =
        pres->get_Slides()->idx_get(0)->get_Shapes()->AddTable(50.0f, 50.0f, System::MakeArray<double>({ 50, 70 }), System::MakeArray<double>({ 50, 50, 50 }));

    System::SharedPtr<IParagraph> paragraph0 = System::MakeObject<Paragraph>();
    paragraph0->get_Portions()->Add(System::MakeObject<Portion>(u"Text "));
    paragraph0->get_Portions()->Add(System::MakeObject<Portion>(u"in0"));
    paragraph0->get_Portions()->Add(System::MakeObject<Portion>(u" Cell"));

    System::SharedPtr<IParagraph> paragraph1 = System::MakeObject<Paragraph>();
    paragraph1->set_Text(u"On0");

    System::SharedPtr<IParagraph> paragraph2 = System::MakeObject<Paragraph>();
    paragraph2->get_Portions()->Add(System::MakeObject<Portion>(u"Hi there "));
    paragraph2->get_Portions()->Add(System::MakeObject<Portion>(u"col0"));

    System::SharedPtr<ICell> cell = tbl->get_Rows()->idx_get(1)->idx_get(1);
    cell->get_TextFrame()->get_Paragraphs()->Clear();
    cell->get_TextFrame()->get_Paragraphs()->Add(paragraph0);
    cell->get_TextFrame()->get_Paragraphs()->Add(paragraph1);
    cell->get_TextFrame()->get_Paragraphs()->Add(paragraph2);

    System::SharedPtr<IAutoShape> autoShape =
        pres->get_Slides()->idx_get(0)->get_Shapes()->AddAutoShape(Aspose::Slides::ShapeType::Rectangle, 400.0f, 100.0f, 60.0f, 120.0f);
    autoShape->get_TextFrame()->set_Text(u"Text in shape");
}

The source code snippet below will add a yellow frame to all paragraphs and blue frame to all portions which contain substring “0”.

In the first step, We’re getting coordinates of the left top corner of the table cell.

double x = tbl->get_X() + cell->get_OffsetX();
double y = tbl->get_Y() + cell->get_OffsetY();

In the next step we’re using IPortion::GetRect() and IParagraph::GetRect() methods in order to add frame to portions and paragraphs.

 {
    auto para_enumerator = cell->get_TextFrame()->get_Paragraphs()->GetEnumerator();
    while (para_enumerator->MoveNext())
    {
        auto para = para_enumerator->get_Current();
        if (para->get_Text() == u"")
            continue;

        System::Drawing::RectangleF rect = para->GetRect();
        System::SharedPtr<IAutoShape> shape =
            pres->get_Slides()->idx_get(0)->get_Shapes()->AddAutoShape(Aspose::Slides::ShapeType::Rectangle,
                rect.get_X() + (float)x, rect.get_Y() + (float)y, rect.get_Width(), rect.get_Height());

        shape->get_FillFormat()->set_FillType(Aspose::Slides::FillType::NoFill);
        shape->get_LineFormat()->get_FillFormat()->get_SolidFillColor()->set_Color(System::Drawing::Color::get_Yellow());
        shape->get_LineFormat()->get_FillFormat()->set_FillType(Aspose::Slides::FillType::Solid);

        auto portion_enumerator = para->get_Portions()->GetEnumerator();
        while (portion_enumerator->MoveNext())
        {
            auto portion = portion_enumerator->get_Current();
            if (portion->get_Text().Contains(u"0"))
            {
                rect = portion->GetRect();
                shape =
                    pres->get_Slides()->idx_get(0)->get_Shapes()->AddAutoShape(Aspose::Slides::ShapeType::Rectangle,
                        rect.get_X() + (float)x, rect.get_Y() + (float)y, rect.get_Width(), rect.get_Height());

                shape->get_FillFormat()->set_FillType(Aspose::Slides::FillType::NoFill);
            }
        }
    }
}

Add frame to AutoShape paragraphs.

 {
    auto para_enumerator = autoShape->get_TextFrame()->get_Paragraphs()->GetEnumerator();
    while (para_enumerator->MoveNext())
    {
        auto para = para_enumerator->get_Current();
        System::Drawing::RectangleF rect = para->GetRect();
        System::SharedPtr<IAutoShape> shape =
            pres->get_Slides()->idx_get(0)->get_Shapes()->AddAutoShape(Aspose::Slides::ShapeType::Rectangle,
                rect.get_X() + autoShape->get_X(), rect.get_Y() + autoShape->get_Y(), rect.get_Width(), rect.get_Height());

        shape->get_FillFormat()->set_FillType(Aspose::Slides::FillType::NoFill);
        shape->get_LineFormat()->get_FillFormat()->get_SolidFillColor()->set_Color(System::Drawing::Color::get_Yellow());
        shape->get_LineFormat()->get_FillFormat()->set_FillType(Aspose::Slides::FillType::Solid);
    }
}

Result:
