Filter Options
From Apache OpenOffice Wiki
< Documentation | DevGuide
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. |
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);
