Hi
I think I have found the right file. But how can I implement this?
I use the jar files from Batik to use the classes from Batik. How can I overwrite a class or method from a class in Batik?
You need to do what they do in the PDF transcoder and replace the bridge class for text in the BridgeContext with the PDFTextBridge:
PDFTextElementBridge pdfTextElementBridge;
pdfTextElementBridge = new PDFTextElementBridge(graphics.getFontInfo());
ctx.putBridge(pdfTextElementBridge);
You will likely need to modify the PDFTextBridge since you don't the font info, but the part about drawing with drawString should be mostly the same.
I use the following code to convert from SVG to WMF:
public boolean saveAsWMF() { boolean bOK = true; FileOutputStream oStream = null; SVGDocument svgDoc = null; BridgeContext ctx = null; UserAgent userAgent = new UserAgentAdapter(); DocumentLoader loader = new DocumentLoader(userAgent); GVTBuilder builder = new GVTBuilder(); GraphicsNode gvtRoot = null;
try { ctx = new BridgeContext(userAgent, loader); ctx.setDynamic(true); svgDoc = (SVGDocument) loader.loadDocument("C:\\Temp\\Test.svg"); gvtRoot = builder.build(ctx, svgDoc);
WMF wmf = new WMF(); WMFGraphics2D wmfGenerator = new WMFGraphics2D(wmf, 300, 200); wmfGenerator.setGDIPenDrawing(false);
oStream = new FileOutputStream(new File("C:\\Temp\\Test.wmf")); gvtRoot.paint(wmfGenerator); wmf.writePlaceableWMF(oStream, 0, 0, 300, 200, 72); oStream.close(); } catch (FileNotFoundException e) { bOK = false; } catch (IOException e) { bOK = false; } return bOK; }
I don't know how to solve my problem. Maybe you can give me a tip. Thanks.
Regards Hans

The problem is that you can't edit the text in PowerPoint f.e.
if it isn't a
text object. And so it should be a text object...
- Whats about this 'hack' in FOP? Where can I find that?
Check out http://xml.apache.org/fop
The hack lives in src/java/org/apache/fop/svg. It is the replacement text bridge.
- Is it possible to use drawString instead of drawGlyphVector?
Maybe if I
use an own class to draw my SVG text derived from SVGGraphics2D? In this derived class I would replace drawGlyphVector with drawString...
This is essentially what the FOP hack does.
Thanks for the help Hans

Hi Hans,

I convert a SVG in a WMF document using the WMFWriter from Piet
Jonas and
Batik 1.5.
Now I have problems with the text rendering. The rendered text
in the WMF
file is not a text object. It is graphic and the result on the
screen is
really bad.
- How is the text in the following SVG row rendered? <text x="11.1230469" y="387.1083984" style="stroke:none;" xml:space="preserve">0</text>
It is drawn with Graphics2D.drawGlyphVector.
- Will the text be written with Graphics2D.drawString form the Batik library?
No draw string isn't nearly powerful enough to handle SVG text.
Or is another Graphics2D method used? The developer of the WMF library says, the Graphics2D methods of his library will be
used instead of
the Graphics2D methods from Batik. And if the Batik library use
drawString
the result would be OK.
- Can I do something, that the text will be drawn with Graphics2D.drawString?
The PDFTranscoder from the FOP project has a 'hack' so very simple text is drawn using 'drawString'. You might look into using that.
