Hi,
I have a SVGOMTextElement, I want to know how to get the text length.
I have tried both getBBox() and getComputedTextLength(), they both
have null values. Would anyone please tell me if I should set anything
before using these methods?
Thanks very much.

Here is my code:
-----------------------------------------------------
SVGOMTextElement basicText = new SVGOMTextElement(null, svgDocument );
basicText.setTextContent(text);
System.out.println("[SVGText::setText] BBox ="+basicText.getBBox());
System.out.println("[SVGText::setText] text
length="+basicText.getComputedTextLength());
------------------------------------------------------
Here is the exceptions
------------------------------------------------------
[SVGText::setText] BBox =null
null
java.lang.NullPointerException
