Title: RE: Re[2]: [cgmo-webcgm] DOM questions and implementation feedback

Still listening to you guys !!!

BB>>>   3) Since WebCGM only allows for restricted text elements, what is
BB>>>   the usefulness of changing the font-size? ie, it can't exceed the
BB>>>   box height?!

CDW>> This is a question that occurred to me when we initially

CDW>> that introduced the change of font size.  I think the restricted
CDW>> text box ends up getting  in the same was as the character height
CDW>> does??

BBAGAIN> It would be good to hear what others think on this one?  The spec will

BBAGAIN> 2) Increase glyph size once layout algorithm is done based on original

I am not the expert, but as a user I am too often facing issues with overlapping text that I will ot be in favour of any modification of the restricted text box, as it may affect the readability of the graphic. For me the correct behaviour is to increment the font size as requested and then compute text layout in the bounding box. I think it is your option 3. From a user point of view it is the safe way, and if the dummy user want a font increase that is not complying with the restricted box this will be his fault and only his. Maybe you can envision that your option 1 may be accessible through a user specification (like a boolean parameter to the function), but I am not sure the benefit will worth the effort to specify and implement correctly this feature.
