little help

[ananth balasubramanyam <ab...@cs.odu.edu>]

Hi all,

I am replacing the text of a text element with a new text string and
am trying to shift the text element, either to the left or the right based
on the the difference in old and new widths(so as to maintain the
center alignment). Here is a sample code. I dont
seem to be visually getting the desired results. Could somebody please
help me with this. Am i doing something wrong ?

SVGOMTextElement textElement ......
..................................
oldWidth = textElement.getComputedTextLength();
..................................
change the text context of the textElement
..................................
newWidth = textElement.getComputedTextLength();

SVGMatrix matrix = textElement.getTransform().getBaseVal().consolidate().getMatrix();
oldX = matrix.getE();

if (oldWidth > newWidth) {
 newX = oldX + ((oldWidth - newWidth) / 2);
} else if (oldWidth < newWidth) {
 newX = oldX - ((newWidth - oldWidth) / 2);
}

matrix.setE(newX);

Is something wrong in the above code.
thanks,
Ananth

Not addressing your actual problem, but why don't you just set
text-anchor="middle" on your text element so you the centering is done
automatically?
