 |
|
hi,
i developed a java application to export ppt.
It works fine, but i want slides to be export in 640x480.
I tried to set the drawpage size but it cuts the slide.
Do you have any idea ? Thanks.

| Code: | Dim aFilterData (3) As New com.sun.star.beans.PropertyValue
aFilterData(0).Name = "PixelWidth"
aFilterData(0).Value = 640
aFilterData(1).Name = "PixelHeight"
aFilterData(1).Value = 480
aFilterData(2).Name = "LogicalWidth";
aFilterData(2).Value = 640
aFilterData(3).Name = "LogicalHeight"
aFilterData(3).Value = 480

Then you just need to set the XExporter.filter - (xExporter = createUnoService "com.sun.star.drawing.GraphicExportFilter") to that filter.
Sorry, can't give you the whole code right now, but i hope this helps a bit.

ok it works fine. I post my code, it can be helpful :
| Code: |
PropertyValue[] loadProps = new PropertyValue[2];
loadProps[0] = new PropertyValue();
loadProps[0].Name = "Hidden";
loadProps[0].Value = new Boolean(true);
// open the document
XComponent component = xcomponentloader
.loadComponentFromURL(url,
"_blank", 0, loadProps);
//System.out.println("Document Opened");
// filter
loadProps = new PropertyValue[3];
// type of image
loadProps[0] = new PropertyValue();
loadProps[0].Name = "MediaType";
loadProps[0].Value = "image/png";
// Height and width
PropertyValue[] filterDatas = new PropertyValue[4];
for(int i = 0; i<4 ; i++){
filterDatas[i] = new PropertyValue();
}
filterDatas[0].Name = "PixelWidth";
filterDatas[0].Value = new Integer(640);
filterDatas[1].Name = "PixelHeight";
filterDatas[1].Value = new Integer(480);
filterDatas[2].Name = "LogicalWidth";
filterDatas[2].Value = new Integer(640);
filterDatas[3].Name = "LogicalHeight";
filterDatas[3].Value = new Integer(480);
XDrawPagesSupplier pagesSupplier = (XDrawPagesSupplier) UnoRuntime
.queryInterface(XDrawPagesSupplier.class, component);
//System.out.println(pagesSupplier.toString());
XDrawPages pages = pagesSupplier.getDrawPages();
int nbPages = pages.getCount();
for (int i = 0; i < nbPages; i++) {
XDrawPage page = (XDrawPage) UnoRuntime.queryInterface(
com.sun.star.drawing.XDrawPage.class, pages
.getByIndex(i));
XNamed xPageName = (XNamed)UnoRuntime.queryInterface(XNamed.class,page);
xPageName.setName(xPageName.getName().replace(' ','_'));
xPageName.setName(removeAccents(xPageName.getName()));
Object GraphicExportFilter = xMultiComponentFactory
.createInstanceWithContext(
"com.sun.star.drawing.GraphicExportFilter",
xComponentContext);
XExporter xExporter = (XExporter) UnoRuntime
.queryInterface(XExporter.class,
GraphicExportFilter);
XComponent xComp = (XComponent) UnoRuntime
.queryInterface(XComponent.class, page);
xExporter.setSourceDocument(xComp);
loadProps[1] = new PropertyValue();
loadProps[1].Name = "URL";
loadProps[1].Value = remoteFolderFullPath+remoteFolder+"/"+(i+1) + "-"+xPageName.getName()+".png";
loadProps[2] = new PropertyValue();
loadProps[2].Name = "FilterData";
loadProps[2].Value = filterDatas;
XFilter xFilter = (XFilter) UnoRuntime.queryInterface(XFilter.class, GraphicExportFilter);
xFilter.filter(loadProps);
System.out.println((i+1) + "-"+xPageName.getName()+".png");
//System.out.println("Page saved to url "+loadProps[1].Value);

Good on you elixir for marking the thread as resolved and posting the code! That's very good netiquette and all of us should do that!
Glad to be able to help. |

Due to this thread http://www.oooforum.org/forum/viewtopic.phtml?t=113679, I tried to get the above code working. With some small modifications it worked indeed. This is the complete Java code I came up with (heavily based on the above one): | Code: | import com.sun.star.beans.PropertyValue;
import com.sun.star.container.XNamed;
import com.sun.star.document.XExporter;
import com.sun.star.document.XFilter;
import com.sun.star.drawing.XDrawPage;
import com.sun.star.drawing.XDrawPages;
import com.sun.star.drawing.XDrawPagesSupplier;
import com.sun.star.frame.XComponentLoader;
import com.sun.star.lang.XComponent;
import com.sun.star.lang.XMultiComponentFactory;
import com.sun.star.uno.UnoRuntime;
import com.sun.star.uno.XComponentContext;
import ooo.connector.BootstrapSocketConnector;
public class PresentationToImage {
private static final String oooExeFolder = "/usr/lib/openoffice/program/";
private static final String loadUrl="file:///tmp/example.odp";
private static final String exportFilterUrl="file:///tmp/example";
private static final int exportWidth = 800;
private static final int exportHeight = 600;
public static void main(String[] args) {
try {
XComponentContext xContext = BootstrapSocketConnector.bootstrap(oooExeFolder);
XMultiComponentFactory xMultiComponentFactory = xContext.getServiceManager();
Object desktop = xMultiComponentFactory.createInstanceWithContext("com.sun.star.frame.Desktop", xContext);
XComponentLoader xcomponentloader = (XComponentLoader) UnoRuntime.queryInterface(XComponentLoader.class, desktop);
XComponent document = xcomponentloader.loadComponentFromURL(loadUrl, "_blank", 0, new PropertyValue[0]);
Object graphicExportFilter = xMultiComponentFactory.createInstanceWithContext("com.sun.star.drawing.GraphicExportFilter", xContext);
extract(document, graphicExportFilter);
}
catch (java.lang.Exception e) {
e.printStackTrace();
}
finally {
System.exit(0);
}
}
private static void extract(XComponent objectDocument, Object graphicExportFilter) throws com.sun.star.uno.Exception {
// Export filter properties
PropertyValue[] exportFilterProps = new PropertyValue[3];
// Type of image
exportFilterProps[0] = new PropertyValue();
exportFilterProps[0].Name = "MediaType";
exportFilterProps[0].Value = "image/png";
// Height and width
PropertyValue[] exportFilterData = new PropertyValue[4];
exportFilterData[0] = new PropertyValue();
exportFilterData[0].Name = "PixelWidth";
exportFilterData[0].Value = new Integer(exportWidth);
exportFilterData[1] = new PropertyValue();
exportFilterData[1].Name = "PixelHeight";
exportFilterData[1].Value = new Integer(exportHeight);
exportFilterData[2] = new PropertyValue();
exportFilterData[2].Name = "LogicalWidth";
exportFilterData[2].Value = new Integer(exportWidth);
exportFilterData[3] = new PropertyValue();
exportFilterData[3].Name = "LogicalHeight";
exportFilterData[3].Value = new Integer(exportHeight);
exportFilterProps[1] = new PropertyValue();
exportFilterProps[1].Name = "FilterData";
exportFilterProps[1].Value = exportFilterData;
// Get slides of document
XDrawPagesSupplier pagesSupplier = (XDrawPagesSupplier) UnoRuntime.queryInterface(XDrawPagesSupplier.class, objectDocument);
XDrawPages pages = pagesSupplier.getDrawPages();
for (int i = 0; i < pages.getCount(); i++) {
// Get slide
XDrawPage page = (XDrawPage) UnoRuntime.queryInterface(com.sun.star.drawing.XDrawPage.class, pages.getByIndex(i));
XNamed xPageName = (XNamed)UnoRuntime.queryInterface(XNamed.class,page);
xPageName.setName(xPageName.getName().replace(' ','_'));
XExporter xExporter = (XExporter) UnoRuntime.queryInterface(XExporter.class, graphicExportFilter);
xExporter.setSourceDocument((XComponent) UnoRuntime.queryInterface(XComponent.class, page));
exportFilterProps[2] = new PropertyValue();
exportFilterProps[2].Name = "URL";
exportFilterProps[2].Value = exportFilterUrl + "-" + xPageName.getName()+"("+(i+1)+").png";
// Store slide with graphic export filter
XFilter xFilter = (XFilter) UnoRuntime.queryInterface(XFilter.class, graphicExportFilter);
xFilter.filter(exportFilterProps);
System.out.println("Page saved to url: "+exportFilterProps[2].Value);
}
}

I've used OOo 3.2.0 on Ubuntu 10.04, NetBeans 6.8 and Java 1.6.0_16. From OO's jar files the code needs juh.jar, jurt.jar, ridl. jar and unoil.jar. For getting connected with OOo the code needs the bootstrapconnector.jar from http://user.services.openoffice.org/en/forum/viewtopic.php?f=44&t=2520.
The code works with ODP (OOo Impress) documents and should work with OOo Draw documents, too. Due to the usage of XDrawPagesSupplier (http://api.openoffice.org/docs/common/ref/com/sun/star/drawing/XDrawPagesSupplier.html) it can not work with OOo Writer or OOo Calc documents. |

How do I make this code work for any kind of document? not only for presentation ones.
I get a NullPointerException on
XDrawPages pages = pagesSupplier.getDrawPages();
Apparently the
XDrawPagesSupplier pagesSupplier = (XDrawPagesSupplier) UnoRuntime.queryInterface(XDrawPagesSupplier.class, objectDocument);
doesn't work for a simple .odt file |

I think, it is not possible to get this code working for any kind of document. |
