You need to build the GVT tree and call the paint method on the
root SVG element:
import org.apache.batik.bridge.UserAgent;
import org.apache.batik.bridge.UserAgentAdapter;
import org.apache.batik.bridge.DocumentLoader;
import org.apache.batik.bridge.BridgeContext;
import org.apache.batik.bridge.GVTBuilder;
import org.apache.batik.gvt.GraphicsNode;
SVGDocument svgDoc;
UserAgent userAgent;
DocumentLoader loader;
BridgeContext ctx;
GVTBuilder builder;
GraphicsNode gn;
userAgent = new UserAgentAdapter();
loader = new DocumentLoader(userAgent);
ctx = new BridgeContext(userAgent, loader);
builder = new GVTBuilder();
gn = builder.build(ctx, svgDoc);
gn.paint(svgGraphics2D);
svgGraphics2D.stream(....);

This my new code of clipping
but i cant associat the SVGGraphics2D with my svgreader
see and tell me if my clipping is good and if something must be coded
/***********************************/
//int width = Integer.parseInt(parama);
//int height = Integer.parseInt(paramb);
SVGTranscoder trans = new SVGTranscoder();
// Creation d un transcoder input
FileInputStream instream = new FileInputStream(rep+Entree);
InputStreamReader istream = new InputStreamReader(instream);
TranscoderInput input = new TranscoderInput(istream);
String svgURI = new File(rep+Entree).toURL().toString();
TranscoderInput input1 = new TranscoderInput(svgURI);
//recupere le document pour le clipper
Document doc = input1.getDocument();
String moi = input1.getURI();
out.println("moi = " + moi);
//erreur dom factory should not be null->mon doc quand je le
recupere doit etre null
//comment lire un fichier puis lui associe une action
//construction du graphics2D mais associe avec le document ouvert
SVGGraphics2D sg2D = new SVGGraphics2D(doc);
sg2D.setClip(0,0,100,100);
sg2D.stream(rep+Sortie);
// Creation d un transcoder output
/* OutputStream ostream */
/*
FileOutputStream outstream = new FileOutputStream(rep+Sortie);
OutputStreamWriter ostream = new OutputStreamWriter(outstream);
TranscoderOutput output = new TranscoderOutput(ostream);
out.println("fichier " + Sortie + " a été généré");
// Sauvegarde de l image
trans.transcode(input,output);

Re: RE:help me please clipping svg
Posted by Bastien DEBLAIS <bd...@iftechnologies.net>.
i have the same problem. Link (associate) the svg document with the
graphics2D
this my code to do a clipping with a svg document :
/******************************************/
<FORM>
fichier (*.svg): <INPUT NAME="Ficsvg"><BR>
nouveau_fichier (*.svg): <INPUT NAME="Ficnsvg"><BR>
dimension (WIDTH): <INPUT NAME="width"><BR>
dimension (HEIGHT): <INPUT NAME="height"><P>
<INPUT TYPE=SUBMIT VALUE="Send It!">
</FORM>
<%
String Entree = (String) request.getParameter("Ficsvg");
String Sortie = (String) request.getParameter("Ficnsvg");
//declaration variable
String rep="c:/pierrestage/WebApplication3/";
if((Entree!=null)&&(Sortie!=null))
{
File fic = new File(rep+Entree);
out.println("Le fichier existe : " + fic.exists());
if(fic.exists()==true)
{
String parama = (String)request.getParameter("width");
String paramb = (String)request.getParameter("height");
if((parama==null)&&(paramb==null))
{
out.println("entrez les valeurs width et height de l image a
afficher");
}
else
{
//int width = Integer.parseInt(parama);
//int height = Integer.parseInt(paramb);
String svgURI = new File(rep+Entree).toURL().toString();
out.println("svgURI = "+svgURI);
DOMImplementation impl =
GenericDOMImplementation.getDOMImplementation();
//normalement je recupere a partir de svgURI et je met sous forme
d un document
//le probleme se trouve soit a ce niveau pour charger le input
//soit c'est le stream pour creer le fichier de Sortie
//ici je creer un nouveau document c'est pas bon
Document doc = impl.createDocument(svgURI, "svg", null);
//comment lire un fichier puis lui associe une action
//construction du graphics2D mais associe avec le document ouvert
svg
SVGGraphics2D sg2D = new SVGGraphics2D(doc);
//fais le clipping un rectagle
sg2D.setClip(0,0,300,300);
sg2D.drawString("test marche ou pas",100,150);
sg2D.drawLine(200,200,250,200) ;
sg2D.setSVGCanvasSize(new Dimension(640,480));
//le clipping marche donc je ne charge pas le document
/*change la valeur height et width de mon clipping
le texte s affiche en entier ou pas en fonction de cette taille
/*ca marche pour l affichage d un texte
pourkoi pour le clipping: je ne charge pas le document svg*/
//ecrit normalement sur le fichier de sortie mon clipping
sg2D.stream(rep+Sortie);
out.println("fichier " + Sortie + " a été généré");
%>
<embed id="idEmbedMap" src="<%=rep+Sortie%>"
type="image/svg+xml" width="800" height="600">
</embed>
<%
}
}
}
%>
