multiple markers drawn

[Thomas Holder]

if both 'marker' and any of 'marker-end', 'marker-mid', 'marker-start' are given for some shape, both markers are drawn on top of eath other. Actually the 'marker' attribute is a shortcut to define all three (end/mid/start) at once, so should override their values.

tested on OS X 10.5.8:

1) Batik 1.7, Firefox 3.5.3, Safari 4.0.3 and Inkscape 0.46-2 render 'marker-start', 'marker-mid' and 'marker-end' and ignore 'marker' (diamond) for all nodes

2) Amaya 11.2 and Inkscape 0.46+devel r22467 render 'marker-start', 'marker-mid' and 'marker-end' and on top 'marker' (diamond) for all nodes.

Is there an SVG viewer that lets 'marker' override 'marker-start', 'marker-mid' and 'marker-end'?

[Thomas Holder (speleo3)]

it depends on attribute order, it seems that last attribute counts. So the order in my example is not good for demonstrating the effect. I'll attach another one, where start/mid/end are defined for the parent group (gets inherited) and the path itself only has 'marker'. Batik renders just the diamonds, inkscape r22417 renders both.

Inkscape 0.46 ignores 'marker' at all, so it's not a regression.

1) Batik 1.7, Firefox 3.5.3 and Safari 4.0.3 render 'marker' (diamond) for all nodes and ignore 'marker-start', 'marker-mid' and 'marker-end'

2) Amaya 11.2 and Inkscape 0.46+devel r22476 render 'marker-start', 'marker-mid' and 'marker-end' and on top 'marker' (diamond) for all nodes.

I don't know in detail what the SVG spec says and how Inkscape should behave (given that it doesn't use the 'marker' attribute itself), but I confirm the multiple markers rendered in Inkscape r22476. Did you test the files with a validator?

[Thomas Holder (speleo3)]

@suv: what is the validator supposed to find?

[su_v (suv-lp)]

You tell me - about the both the presence of marker and the 'marker-start/mid/end' attributes? But you are right, it wasn't a thoughtful comment - the case of the inheritance in the second example with groups clearly demonstrates how both attributes might be present yet one of them needs to take precedence. Sorry ;-) I'm an SVG/XML ignoramus - obviously!

[su_v (suv-lp)]

Raising importance given that the release notes 0.47 say among others in 'Notable bug fixes':
«The shorthand 'marker' property is now correctly interpreted (SVG test suite painting-marker-03-f.svg). »

[Beluga (buovjaga)]

Still confirmed.
