Hello,
I am having a problem with the SVGOMTextElement.getSubStringLength
method.
In the following code, this.selectMask is a SVGOMRectElement and
this.text a SVGOMTextElement.
It tries to set the width of the <rect> element to the length of the
text showed in the <text> element.
1: try {
2: this.selectMask.setAttribute("width",
Float.toString(this.text.getSubStringLength(start, length)));
3: } catch (NullPointerException npe) {
4: System.out.println("selection: '" +
this.text.getTextContent().substring(start, start + length) + "'");
5: npe.printStackTrace();
6: }
The output is following:
selection: 'Hello, '
java.lang.NullPointerException

at (attached source code, line 2)
...
The exception is raised only when the substring is at the end of the
text content, and when this content is ended by a space character (' ').
Is this a bug ? If it is not, do I have to trim the substring, and get
the length of this new string from the <text> element ?
Is not there a way to have this space included in the calculation ?
Paul
