Hi,
I tried this solution and it's more accurate, but it's not the "ultimate"
solution for my space problem.
In fact, i compute height and width of each character in a String with the
following code :
SVGTextElement retourLigne = (SVGTextElement)
docCalcul.createElementNS(svgNS, "text");
retourLigne.setAttributeNS(null, "x", "0");
retourLigne.setAttributeNS(null, "y", "0");
retourLigne.setAttributeNS(null, "font-family", fontFamily);
retourLigne.setAttributeNS(null, "font-size",
String.valueOf(fontSize));
retourLigne.setAttributeNS(xmlNS, "xml:space", "preserve");
int retour = 0;
Text tmpText = docCalcul.createTextNode(string);
retourLigne.appendChild(tmpText);
docCalcul.getDocumentElement().appendChild(retourLigne);
retour += retourLigne.getEndPositionOfChar(0).getX();
docCalcul.getDocumentElement().removeChild(retourLigne);
It's worked well for all character but the space width isn't exact.
Can you tell me why ?
I need an exact size for my compute.
Here is a snapshot of the result :
Each red rectangle is the bounding rectangle of a character.

You can easily see the problem on the first space.
The more space i have in a string, the biggest the error is !
Cheers,
