Open Drawing documents

you need to specifiy the URL of the document to load for loadComponentFromURL() as “private:factory/sdraw”

Draw document structure

Draw documents maintain their drawing content on draw pages, master pages and layers. If a new draw document is opened, it contains one slide that corresponds to a DrawPage service. Switching to Master View brings up the master page handled by the service MasterPage. The Layer View allows access to layers to structure your drawings. These layers can be controlled through Layer and LayerManager.

The DrawingDocument service has following interfaces for this purposes:

 XDrawPagesSupplier: 
 XMasterPagesSupplier: 
 XLayerSupplier: 
 XStyleFamiliesSupplier: 

com.sun.star.drawing.XDrawPageSupplier and com.sun.star.drawing.XMasterPagesSupplier supplies XDrawPages and com.sun.star.drawing.MasterPage via com.sun.star.container.XIndexAccess. Each DrawPage has support com.sun.star.drawing.XShapes interface to manage shapes in this DrawPage.

The brief summary to access the single shape in Drawing document might be described as:

1. Open Drawing document
2. Querying DrawPagesSupplier interface of Drawing document
3. Call getDrawPages() method of DrawPagesSupplier to get DrawPages
4. Querying XIndexAccess interface of DrawPages
5. Single DrawPage can be accessd through method of getByIndex
6. However, getByIndex method returns ANY type, you should querying com.sun.star.drawing.DrawPage interface before using it.
7. Going a little bit further, Querying com.sun.star.drawing.XShapes interface of com.sun.star.drawing.DrawPage to gain access to the list of com.sun.star.drawing.Shapes

Shapes

Drawings consist of shapes on draw pages. Shapes are drawing elements, such as rectangles, circles, polygons, and lines. To create a drawing, get a shape by its service name at the ServiceFactory of a drawing document and add it to the appropriate DrawPage.

        //get MSF
        com.sun.star.lang.XMultiServiceFactory xDocMSF =
            (com.sun.star.lang.XMultiServiceFactory)UnoRuntime.queryInterface(
                com.sun.star.lang.XMultiServiceFactory.class, xDocComp );
 
        ...
 
        oInt = xDocMSF.createInstance("com.sun.star.drawing.EllipseShape");
        xShape = (com.sun.star.drawing.XShape)UnoRuntime.queryInterface(
                    com.sun.star.drawing.XShape.class, oInt);
 
        ...
 
        // set the size and positions
        size.Height = height;
        size.Width = width;
        position.X = x;
        position.Y = y;
        xShape.setSize(size);
        xShape.setPosition(position);

ServiceFactory can create several kind of Shape Service, they could be LineShape, PolyLineShape, RectangleShape, TextShape etc.
