Hope that helps,

Hi Ingrid,

 

The draw page of the chart has only one shape (drawPage.getCount()returns
1). I've tried to use the draw page for exporting but It was failed, no
image has been exported. The exporting code is:

 

            XDrawPageSupplier drawPageSupplier =

                  UnoRuntime.queryInterface(XDrawPageSupplier.class,
aChartDoc);

            XDrawPage drawPage = drawPageSupplier.getDrawPage();

            

            XComponent xDrawPageComp = (XComponent)
UnoRuntime.queryInterface(XComponent.class, 

                             drawPage);

                  

            //Create an exporter

            XExporter exporter = (XExporter)UnoRuntime.queryInterface(

                              XExporter.class,

 
xMultiServiceFactory.createInstance("com.sun.star.drawing.GraphicExportFilte
r"));

                  

            PropertyValue[] exportProperties = new PropertyValue[2];

            exportProperties[0] = new PropertyValue();

            exportProperties[0].Name = "MediaType";

            exportProperties[0].Value = "image/jpeg";

           

            exportProperties[1] = new PropertyValue();

            exportProperties[1].Name = "URL";

            exportProperties[1].Value = "file:///E:/Temp/Chart_OO.jpeg
<file:///E:\Temp\Chart_OO.jpeg> ";

            

            exporter.setSourceDocument(xDrawPageComp);

            XFilter drawFilter = (XFilter)
UnoRuntime.queryInterface(XFilter.class, exporter);

            drawFilter.filter(exportProperties);
