GetImage()

IParagraph::GetImage() method

Returns an image of the paragraph.

virtual System::SharedPtr<IImage> Aspose::Slides::IParagraph::GetImage()=0

Return Value

An image containing the rendered paragraph, or null

Remarks

if the paragraph cannot be found in its parent collection, has no valid rendering bounds, or an error occurs while rendering the image.

The following example shows how to render a paragraph as an image:

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

System::SharedPtr<IAutoShape> shape = pres->get_Slide(0)->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 50.0f, 50.0f, 150.0f, 50.0f);
System::SharedPtr<IParagraph> paragraph = shape->get_TextFrame()->get_Paragraph(0);
paragraph->set_Text(u"Aspose Paragraph GetImage() Example");

System::SharedPtr<IImage> paragraphImage = paragraph->GetImage();
paragraphImage->Save(u"paragraph.png");

IParagraph::GetImage(float, float) method

Returns an image of the paragraph with the specified scale.

virtual System::SharedPtr<IImage> Aspose::Slides::IParagraph::GetImage(float scaleX, float scaleY)=0

Arguments

ParameterTypeDescription
scaleXfloatThe horizontal scale factor applied to the paragraph image.
scaleYfloatThe vertical scale factor applied to the paragraph image.

Return Value

An image containing the rendered paragraph, or null

Remarks

if the paragraph cannot be found in its parent collection, has no valid rendering bounds, or an error occurs while rendering the image.

The following example shows how to render each text box paragraph on a slide as an image with custom scaling:

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();
System::SharedPtr<ISlide> slide = pres->get_Slide(0);

int shapeIndex = 0;

for (auto&& shape : slide->get_Shapes())
{
    System::SharedPtr<IAutoShape> autoShape = System::AsCast<IAutoShape>(shape);
    if (autoShape == nullptr)
    {
        continue;
    }

    int paragraphIndex = 0;
    for (auto&& paragraph : autoShape->get_TextFrame()->get_Paragraphs())
    {
        paragraphIndex++;
        System::SharedPtr<IImage> paragraphImage = paragraph->GetImage(2.0f, 2.0f);
        paragraphImage->Save(System::String::Format(u"shape{0}_paragraph{1}.png", shapeIndex, paragraphIndex));
    }
}
