textLength

[Jim Ley <ji...@jibbering.com>]

Hi.

When I set the textLength of a text element, Squiggle appears to offset
the start of the first character of the group somewhat so it no longers
starts at the location I tell it.

See http://jibbering.com/2002/8/svg-textlength.svg

You'll see that even though the text is set to to start at 100px in each
example it moves to the right depending on the size of the font, what
appears to be happening is that the textLength is constrained but only
after the lead in space of the font has already been added.

Cheers,

Jim.

Of course, feel free.

Excellent, thanks.

    This is now fixed in the current CVS code base.

    Correct, the first glyphs lead in space wasn't being scaled, it is
now.  This also revealed a complimentary bug in the visual advance
code that caused centered/end anchored text to be slightly off in some
cases (I had noticed it the last time I worked on the code, but I
couldn't track down the source of the bug - fixing your bug made it
'easy' :).
