Hi Armin, hi Michael,
Michael, I have put you an CC, because this is about ODF. Do you
prefer one of the ideas (A)(B)(C)(D) or have a better idea?
Yes, pls add your 2ct.
(D)
Add
<rng:zeroOrMore>
<rng:ref name="svg-stop"/>
</rng:zeroOrMore>
as child elements to <draw:gradient>
Add that in case <svg:stop> child elements exist, draw:start-color
together with draw:start-intensity is treated as being a <svg:stop>
element with svg:offset="0%" and svg:opacity="1" before all given
<svg:stop> elements,
and draw:end-color together with draw:end-intensity is treated as
being a svg:stop element with svg:offset="100%" and svg:opacity="1"
after all given <svg:stop> elements,
and draw:gradient-step-count is treated as "0".
Specify that the rules in 13.2.4 SVG 1.1. ... shall be followed.
Thanks, that looks good to me, see below.
I would take out from this the StartColor (AKA offset == 0.0) and
the EndColor (AKA offset == 1.0), so in the normal case there would
be no change at all. >
If there are ColorSteps with offset != 0.0 or 1.0 I would create
that extra-entries for these.
What do you mean by "take out"?
Just that for 0% I would use our draw:start-color and for 100% our
draw:end-color. I would only write new entries in svg-conform
semantic for offsets ]0%..100%[. This is to stay as compatible as
possible. It also makes no sense to 'double' the information with
having the same color represented e.g. for StartColor once as
draw:start-color and once as <stop offset="0%"/>.
I think, that would be like I have described as way (D).
Yes, I agree and that's what I would suggest to do for now. It stays as
compatible as possible and the incremental 'bigger' solutions will be
possible based on that AFAICT.
Because the introduction of theme colors, it might be needed to extend
<svg:stop> to not only have stop-color attribute in the sense of SVG
but allow a reference to a scheme-color in addition. In case of (D)
that would have to be added for start- and end-color too.
Will think about that, too...
Kind regards,
Regina
Regards,
Armin
