Hi all,
I'm wondering if it's really simple to implement those methods. I'm pretty new in the Batik code, so
correct me if I'm wrong. It seems to me that because non-formatted values are clearly separated from formatted/dynamic values it's not easy to make the latter available at the OM level. Each OM object is
*temporarily* associated to GVT object where formatted and dynamic values are available.
I'm curious to know how you would do it. Can you give us some hints?
Well, there are two things. First it's not clear that 'getTextLength()' is associated with any dynamic value. It is supposed to be tied to the 'textLength' attribute, which is very easy to associate (as you seem to have seen).
The only interesting question is what should it return if textLength isn't set? One could argue that it should return the computed text length (i.e. the value of getComputedTextLength()). This would of course then make the two methods twins of each other. If textLength is set the computed text length is supposed to be the value of textLength, and if textLength isn't set then it returns the value of get computed text length.
In any case if textLength isn't set then just call getComputedTextLength.
Thanks Lionel
Hi Harald,

I am trying to get the rendered length of a SVG Text Element. As far as i understood, the getTextLength() Method of SVGTextContentElement is supposed to do this.
No you want the "getComputedTextLength" function, "getTextLength" is tied to the "textLength" attribute (which should, if set, be the same as the computed text length but for most content it is not). The "getComputedTextLength()" function _is_ implemented.
However when i tried this, a RuntimeException was thrown and by looking at the code I found out that the Method returns an implementation of AbstractSVGAnimatedLength where getDefaultValue() and getAnimatedValue() are not implemented. My question is, wether there are any plans for implementing this method(s) ?
There is (since it's pretty simple for Batik, in fact I'm not sure why it isn't already). However, as I said above it really wouldn't help you much ;)
