Public API Changes

Support for rendering an image of an individual paragraph

The new GetImage methods have been added to the IParagraph interface and Paragraph class. These methods allow you to render a paragraph as an image.

SharedPtr<IImage> GetImage();
SharedPtr<IImage> GetImage(float scaleX, float scaleY);

Usage examples

The following example shows how to render each paragraph in all AutoShapes on a slide as an image with custom scaling:

SharedPtr<Presentation> pres = MakeObject<Presentation>(u"sample.pptx");
SharedPtr<ISlide> slide = pres->get_Slide(0);

int shapeIndex = 0;
for (auto&& shape : slide->get_Shapes())
{
    shapeIndex++;

    SharedPtr<IAutoShape> autoShape = System::AsCast<IAutoShape>(shape);
    if (autoShape == nullptr || autoShape->get_TextFrame() == nullptr)
        continue;

    int paragraphIndex = 0;
    for (auto&& paragraph : autoShape->get_TextFrame()->get_Paragraphs())
    {
        paragraphIndex++;

        SharedPtr<IImage> paragraphImage = paragraph->GetImage(2.0f, 2.0f);
        paragraphImage->Save(String::Format(u"shape{0}_paragraph{1}.png", shapeIndex, paragraphIndex));
    }
}

The following example shows how to render each paragraph in a table:

SharedPtr<Presentation> pres = MakeObject<Presentation>(u"sample.pptx");
SharedPtr<ISlide> slide = pres->get_Slide(0);
SharedPtr<Table> table = System::AsCast<Table>(slide->get_Shape(0));

int paragraphIndex = 0;
const int rowsCount = table->get_Rows()->get_Count();
const int columnsCount = table->get_Columns()->get_Count();

for (int iRow = 0; iRow < rowsCount; iRow++)
{
    for (int iCol = 0; iCol < columnsCount; iCol++)
    {
        auto cell = System::ExplicitCast<Aspose::Slides::Cell>(table->idx_get(iCol, iRow));
        if (cell->get_TextFrame() == nullptr)
            continue;

        foreach (auto&& parapgraph : cell->get_TextFrame()->get_Paragraphs())
        {
            paragraphIndex++;

            SharedPtr<IImage> paragraphImage = paragraph->GetImage();
            paragraphImage->Save(String::Format(u"paragraph{0}.png", paragraphIndex));
        }
    }
}
