769939 - Externally referenced SVG Patterns can't reference local Symbols

Status: RESOLVED DUPLICATE of bug 866655

(Core :: SVG, defect)

Description

[mel]

Attachment: bar.svg

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:13.0) Gecko/20100101 Firefox/13.0.1
Build ID: 20120615040410

Steps to reproduce:

Firefox 13.0.1; Linux (Ubuntu 10.04)

Two files: foo.svg references a pattern contained within bar.svg
The pattern in bar.svg references a symbol (red and blue vertical stripes), also in bar.svg

I have attached the bar.svg I used to test. My test foo.svg contains just the <rect> which appers at the end of bar.svg, but having fill="bar.svg#pattern".


Actual results:

* The pattern, when rendered inside bar.svg, includes the <symbol> from bar.svg
* The pattern, when rendered inside foo.svg, does not include the <symbol> from bar.svg



Expected results:

In both SVG files, the rendered pattern should include the <symbol>

The URL for bar.svg in bugzilla is https://bug769939.bugzilla.mozilla.org/attachment.cgi?id=638130 so you should be able to construct a foo.svg that references it as you describe.

bar.svg has no height and width for the use element or the symbol element, their size therefore defaults to 100%. Because of bug 866655 we resolve that 100% by looking at the width of the root SVG element, but that isn't set either so that defaults to 100% too.

When you view bar.svg directly the 100% height/width of the root SVG element is resolved as the viewport height/width. When you view it indirectly (as a resource document) then there's nothing to resolve the height/width against so the width/height resolves to 0 and therefore the width/height of the symbol and use resolve to 0 and since we clip them, we clip to an empty rect.

If you replace the use/symbol with an svg element you get the same result.
