public float renderToSize(java.awt.Graphics2D graphics, float x, float y, float width, float height)
                  throws java.lang.Exception

Renders the shape into a java.awt.Graphics2D object to a specified size.

Parameters:

graphics - The object where to render to.

x - The X coordinate (in world units) of the top left corner of the rendered shape.

y - The Y coordinate (in world units) of the top left corner of the rendered shape.

width - The maximum width (in world units) that can be occupied by the rendered shape.

height - The maximum height (in world units) that can be occupied by the rendered shape.

Returns:

The scale that was automatically calculated for the rendered shape to fit the specified size.

Example:

Shows how to render a shape with a Graphics object.

public static class JFrameGraphics extends JPanel {
    public void paint(Graphics graphics) {
        try {
            // Open a document and get its first shape, which is a chart
            Document doc = new Document(getMyDir() + "Shape.VarietyOfShapes.docx");

            Shape shape = (Shape) doc.getChild(NodeType.SHAPE, 1, true);

            // Create a ShapeRenderer instance and a Graphics object
            // The ShapeRenderer will render the shape that is passed during construction over the Graphics object
            // Whatever is rendered on this Graphics object will be displayed on the screen inside this form
            ShapeRenderer renderer = new ShapeRenderer(shape);

            // Call this method on the renderer to render the chart in the passed Graphics object,
            // on a specified x/y coordinate and scale
            renderer.renderToScale((Graphics2D) graphics, 0f, 0f, 1.5f);

            // Get another shape from the document, and render it to a specific size instead of a linear scale
            GroupShape groupShape = (GroupShape) doc.getChild(NodeType.GROUP_SHAPE, 0, true);
            renderer = new ShapeRenderer(groupShape);
            renderer.renderToSize((Graphics2D) graphics, 500f, 400f, 100f, 200f);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

        // Create windows form for present shapes

public void save(java.io.OutputStream stream, ImageSaveOptions saveOptions)
         throws java.lang.Exception

Renders the shape into an image and saves into a stream.

Parameters:

stream - The stream where to save the image of the shape.

saveOptions - Specifies the options that control how the shape is rendered and saved. Can be null. If this is null, the image will be saved in the PNG format.

Example:

Shows how to export shapes to files in the local file system using a shape renderer.

// Open a document that contains shapes and get its shape collection
Document doc = new Document(getMyDir() + "Shape.VarietyOfShapes.docx");
NodeCollection shapes = doc.getChildNodes(NodeType.SHAPE, true);
Assert.assertEquals(7, shapes.getCount());

// There are 7 shapes in the document, with one group shape with 2 child shapes
// The child shapes will be rendered but their parent group shape will be skipped, so we will see 6 output files
for (Shape shape : (Iterable<Shape>) shapes) {
    ShapeRenderer renderer = shape.getShapeRenderer();
    ImageSaveOptions options = new ImageSaveOptions(SaveFormat.PNG);
    renderer.save(getArtifactsDir() + MessageFormat.format("Shape.ShapeRenderer {0}.png", shape.getName()), options);
}

public void save(java.lang.String fileName, ImageSaveOptions saveOptions)
         throws java.lang.Exception

Renders the shape into an image and saves into a file.

Parameters:

fileName - The name for the image file. If a file with the specified name already exists, the existing file is overwritten.

saveOptions - Specifies the options that control how the shape is rendered and saved. Can be null.

Example:

Shows how to convert specific object into image

Document doc = new Document(getMyDir() + "Shape.OfficeMath.docx");

//Get OfficeMath node from the document and render this as image (you can also do the same with the Shape node)
OfficeMath math = (OfficeMath) doc.getChild(NodeType.OFFICE_MATH, 0, true);
math.getMathRenderer().save(getArtifactsDir() + "Shape.OfficeMath.svg", new ImageSaveOptions(SaveFormat.SVG));
