<scribe> scribenick: pdengler
pdengler: CSS defined properties (e.g. 'font-size') must follow CSS
syntax and thus require units for non-zero <length> values. See 6.1
for a list of CSS defined properties
... This is the proposed change of language correct?
ed: Not a problem going to a property for x and y
shepazu: When using attributes use SVG unit values, when using CSS
use unit values
ed: not sure this is what browers do
Tav: Not sure if this is what we are saying
<ed>

vg

shepazu: Need to coordinate w/ CSS working group
... Take HTML approach that CSS working group needs to reasses the
issue
... Need to do with the Fx task force
... Tooling and existing content does styling with unitless values.
<scribe> ACTION: shezpazu to Work with Tav and CSS working group on
understanding the requirment for CSS/SVG Unitless Properties
[recorded in
[18]http://www.w3.org/2010/07/20-svg-minutes.html#action02]

<trackbot> Created ACTION-2826 - Work with Tav and CSS working group
on understanding the requirment for CSS/SVG Unitless Properties [on
Doug Schepers - due 2010-07-27].
ed: Any other last call items; perhaps one or twomore
<ed> ISSUE-2353

rectangles were suppose to describe

<scribe> ACTION: ed To make modification to spec around feImage
coordinates regarding issue 2353 [recorded in
[21]http://www.w3.org/2010/07/20-svg-minutes.html#action05]
<trackbot> Created ACTION-2827 - Make modification to spec around
feImage coordinates regarding issue 2353 [on Erik Dahlström - due
2010-07-27].
ed: With no more last call items for today we will move on to other
issues
... Topic : Default sizing of SVG in HTML5
shepazu: If default size is 100% 100%, if there is a view box, you
can infer size
ed: not necessarily size
... viewbox infers ratio, not size
... It would help to have an example of what you expect and what you
get
... We should have samples in the test suite
pdengler: They are there, but they are not necessarily complicated
enough
<scribe> ACTION: pdengler to create more sophisticated test cases
around <image> sizing and viewBox [recorded in
[22]http://www.w3.org/2010/07/20-svg-minutes.html#action06]
<trackbot> Created ACTION-2828 - Create more sophisticated test
cases around <image> sizing and viewBox [on Patrick Dengler - due
2010-07-27].
pdengler: When you have a simple <svg><circle...> the default size
is 300px,150px as last fall back
ed: Will resolve differently depending on outer container
shepazu: Need to have default intrinsic height in 2.0
<scribe> ACTION: patd to investigate default <svg> sizing in HTML5
[recorded in
[23]http://www.w3.org/2010/07/20-svg-minutes.html#action07]
<trackbot> Sorry, couldn't find user - patd
<scribe> ACTION: pdengler to investigate default <svg> sizing in
HTML5 [recorded in
[24]http://www.w3.org/2010/07/20-svg-minutes.html#action08]
<trackbot> Created ACTION-2829 - Investigate default <svg> sizing in
HTML5 [on Patrick Dengler - due 2010-07-27].
DrawImage in <cavas>
shepazu: For canvas, since SVG is a "vector", I think the drawImage
should take a width and height parameter
ed: It does take a width and height, but it doesn't always have them
available
shepazu: In the case where there isn't a width and height, we need
to determine what to do
<ed>
[25]http://lists.w3.org/Archives/Public/www-svg/2010Jul/0074.html
[25] http://lists.w3.org/Archives/Public/www-svg/2010Jul/0074.html
shepazu: If it has a width and height, use the width and height of
the viewBox in pixels
ed: Not sure this is a great idea
... If you don't pass a width and height when you call drawImage,
the SVG image needs to be drawn into an area, you could use the
<canvas> width and height
... Then the underlying viewBox could still be used for the
coordinate system
... We have experimental code dealing with this which probably needs
further fixing
pdengler: I like this.
ed: We should get this back to the HTML/Canvas effort
<scribe> ACTION: pdengler to get to HTML5 working group <canvas>
about using canvas width and height for SVG width and height
[recorded in
[26]http://www.w3.org/2010/07/20-svg-minutes.html#action09]
<trackbot> Created ACTION-2830 - Get to HTML5 working group <canvas>
about using canvas width and height for SVG width and height [on
Patrick Dengler - due 2010-07-27].
ed: We need to get jwatt's opinion as well
pdengler: I will use this as a first poposal and be prepared to back
it out of Jonothan does not like it
load events on svg elements
<ed>

dispatched to them -- raised
<trackbot> [28]http://www.w3.org/Graphics/SVG/WG/track/issues/2254
[28] http://www.w3.org/Graphics/SVG/WG/track/issues/2254
ed: What we concluded that loadevents on elements that have external
resources; for other elements we couldn't care less; but that's not
what the spec says
... And there is at least one test that checks for these

ie9 clarification issues
<scribe> Topic : Markers and styles at point of reference
<ed>
[34]http://lists.w3.org/Archives/Public/www-svg/2010Jul/0066.html
[34] http://lists.w3.org/Archives/Public/www-svg/2010Jul/0066.html
pdengler: We should be using markers styled at the point of
reference
shepazu: There is an issue that there is a lot of content out there
that already follows this
... The way we talked about it, was to have a different method for
styling the markers
<ed>
[35]http://dev.w3.org/SVG/profiles/1.1F2/test/svg/painting-marker-02
-f.svg
[35] http://dev.w3.org/SVG/profiles/1.1F2/test/svg/painting-marker-02-f.svg
pdengler: Looking at this test
[36]http://dev.w3.org/SVG/profiles/1.1F2/test/harness/htmlEmbed/pain
ting-marker-02-f.html
[36]
http://dev.w3.org/SVG/profiles/1.1F2/test/harness/htmlEmbed/painting-marker-02-f.html
<ed> <marker id=foo><rect fill="currentColor"></marker> <line
marker-start="url(#foo)" color="blue"/>
shepazu: unforutnately, the conceptual model that a marker was not a
<use>
... Tried a number of ways to change fill/stroke of markers
... As a forward change in SVG 2.0, but we could add this in one of
two ways;
... Keep it backward compatible with marker-fill/marker-stroke; this
would support both use cases
... Another way to do it is to inherit the fill and stroke of it's
referencing parent
Tav: You can't just inherit the stroke of the parent
shepazu: most content defines the style for the marker.
... you don't get to override this. It's not as much as an issue as
I thought, as existing content is already defining
stroke/stroke-width colors
<ed> ok, we can forget the marker + color example i pasted earlier,
doesn't work :)
shepazu: So we could redefine it for SVG 2.0; but for the author is
best for us define marker specifc properties
<scribe> ACTION: ed: to investigate markers and where and when to
apply style [recorded in
[37]http://www.w3.org/2010/07/20-svg-minutes.html#action14]
<trackbot> Created ACTION-2832 - Investigate markers and where and
when to apply style [on Erik Dahlström - due 2010-07-27].
Tav: Suppose there is an arrow. The normal thing to do would be to
have the arrow head to inherit the stroke-color of the path for the
fill of the marker
shepazu: How do we achieve that effect?
... Most of the time, authors are using the path without a fill
