Re[2]: HSLF slide.draw() is does not render entire image.
In ppt slides equations are embedded OLE objects. Each OLE object
consists of two parts:
- snapshot in WMF format. This is what needs to be rendered.
- the actual binary OLE data. This part is activated by double-click.
Since rendering of WMF is not supported by JDK, the equations don't
appear in the created images.
In next versions of HSLF I plan to use Batik http://xmlgraphics.apache.org/batik/ which
includes a WMF transcoder:
http://xmlgraphics.apache.org/batik/javadoc/org/apache/batik/transcoder/wmf/tosvg/WMFPainter.html
If you feel like researching this subject, I can explain how to
extend HSLF code to use third-party image renderers.

You need to make sure that each platform has all the necessary fonts
installed.
If I recall correctly on Windows they go into the system, but on Unix
systems they need to go into the Java setup - often - /usr/java/jre/
lib/fonts
Possibly you'll need to install the fonts into java on Windows as
well. I don't know if we know if Batik requires that.

Re: HSLF slide.draw() is does not render entire image.
Posted by Travis Patterson <ma...@unm.edu>.
This works pretty well. There are a couple of issues with it though.
There seems to be something strange with the way that Java renders the
fonts of the equations. Which characters are correctly rendered is
based entirely on which platform I run the program on. Also, the
placement of some of the equations isn't quite right. Most of them
look fine but there are a few that are getting garbled.

Re: HSLF slide.draw() is does not render entire image.

I extended HSLF to support custom image renderers. Here is what you need to do to render WMF:
1. Checkout the latest trunk.
2. Download Apache Batik, http://xmlgraphics.apache.org/batik/
3. Include the Batik jar in the classpath.
4. Below is a mock up a class that can render WMF using Batik. Include it in your project.
package org.apache.poi.hslf.blip;
import org.apache.poi.hslf.usermodel.PictureData;
import org.apache.poi.hslf.model.Picture;
import java.awt.*;
import java.io.*;
/**
* Use Apache Batik to render WMF into Graphics2D
*
* @author Yegor Kozlov
*/
public class WMFImagePainter implements ImagePainter {
public void paint(Graphics2D graphics, PictureData pict, Picture parent) {
DataInputStream is = new DataInputStream(new ByteArrayInputStream(pict.getData()));
org.apache.batik.transcoder.wmf.tosvg.WMFRecordStore wmfStore =
new org.apache.batik.transcoder.wmf.tosvg.WMFRecordStore();
try {
wmfStore.read(is);
} catch (IOException e){
e.printStackTrace();
return;
}
Rectangle anchor = parent.getAnchor();
float scale = (float)anchor.width/wmfStore.getWidthPixels();
org.apache.batik.transcoder.wmf.tosvg.WMFPainter painter =
new org.apache.batik.transcoder.wmf.tosvg.WMFPainter(wmfStore, 0, 0, scale);
graphics.translate(anchor.x, anchor.y);
painter.paint(graphics);
}
}
I didn't research it deeply. Try to play with the Batik classes.
5. Add the following line before rendering:
PictureData.setImagePainter(Picture.WMF, new WMFImagePainter ());
6. Subsequent calls of Slide.draw(Graphics gr) will use WMFImagePainter for WMF images and
you should see WMF in the generated images. Let me know about your results.
