Rotating text using the DOM api

[David Smith <Da...@aeroint.com>]

I am trying to rotate a text element so it stands vertical without using
"writing-mode".

Currently I do it by:

    elem.setAttributeNS(null, "writing-mode", "tb" );   

But this rotates the text 90 degrees clockwise.  I want to be able to rotate
it 90 degrees anticlockwise.

I have tried to use 

    elem.setAttributeNS(null, "rotate", "90" );   

 - which i thought would have been the obvious solution - but this has no
effect at all.

Is this a bug in batik?  Or am I using the wrong attribute?

Thanks in advance,
Dave Smith

Re: Rotating text using the DOM api

David,

I think there are two issues:

a. Batik does not support dynamic updates through the DOM yet, and 
   this explains that whatever you do through the DOM API is not 
   reflected on screen.

b. The rotate attribute applies a rotation to each glyph, no to
   the whole string, so I think it will not do what you want.
   You may want to try:
   elem.setAttributeNS(null, "transform", "rotate(90, xxx, yyy)");
   where xxx and yyy are your <text> anchor.

I hope this helps.
Vincent.
