The method filter() takes a sequence of PropertyValue structs describing the filter parameters. The following properties from the com.sun.star.document.MediaDescriptor are supported:
| Properties of com.sun.star.document.MediaDescriptor supported by GraphicExportFilter | |
|---|---|
| MediaType | Depending on the export filters supported by this component, this is the mime type of the target graphic file. The mime types currently supported are:
image/x-MS-bmp application/dxf application/postscript image/gif image/jpeg image/png image/x-pict image/x-pcx image/x-portable-bitmap image/x-portable-graymap image/x-portable-pixmap image/x-cmu-raster image/targa image/tiff image/x-xbitmap image/x-xpixmap image/svg+xml |
| FilterName | This property can been used if no MediaType exists with "Windows Metafile" or "Enhanced Metafile". FilterName has to be set to the extension of these graphic formats (WMF, EMF, BMP).
|
| URL | The target URL of the file that is created during export. |
 |
If necessary, use the interface XMimeTypeInfo to get all mime types supported by the GraphicExportFilter. It offers the following methods:
boolean supportsMimeType( [in] string MimeTypeName ) sequence< string > getSupportedMimeTypeNames() XMimeTypeInfo is currently not supported by the GraphicExportFilter. |
The following example exports a draw page xPage from a given document xDrawDoc:
//get draw pages
com.sun.star.drawing.XDrawPagesSupplier xPageSupplier = (com.sun.star.drawing.XDrawPagesSupplier)
UnoRuntime.queryInterface(com.sun.star.drawing.XDrawPagesSupplier.class, xDrawDoc);
com.sun.star.drawing.XDrawPages xDrawPages = xPageSupplier.getDrawPages();
// first page
Object page = xDrawPages.getByIndex(0);
com.sun.star.drawing.XDrawPage xPage = (com.sun.star.drawing.XDrawPage)UnoRuntime.queryInterface(
com.sun.star.drawing.XDrawPage.class, page);
Object GraphicExportFilter = xServiceFactory.createInstance(
"com.sun.star.drawing.GraphicExportFilter");
// use the XExporter interface to set xPage as source component
// for the GraphicExportFilter
XExporter xExporter = (XExporter)UnoRuntime.queryInterface(
XExporter.class, GraphicExportFilter );
XComponent xComp = (XComponent)UnoRuntime.queryInterface(XComponent.class, xPage);
xExporter.setSourceDocument(xComp);
// prepare the media descriptor for the filter() method in XFilter
PropertyValue aProps[] = new PropertyValue[2];
aProps[0] = new PropertyValue();
aProps[0].Name = "MediaType";
aProps[0].Value = "image/gif";
// for some graphic formats, e.g. Windows Metafile, there is no Mime type,
// therefore it is also possible to use the property FilterName with
// Filter names as defined in the file TypeDetection.xml (see "Storing")
/* aProps[0].Name = "FilterName";
aProps[0].Value = "WMF - MS Windows Metafile";
*/
aProps[1] = new PropertyValue();
aProps[1].Name = "URL";
aProps[1].Value = "file:///home/images/page1.gif";
// get XFilter interface and launch the export
XFilter xFilter = (XFilter) UnoRuntime.queryInterface(
XFilter.class, GraphicExportFilter);
xFilter.filter(aProps);
