ISSUE-2021: Bounding box of <image> subject to aspect-ratio preservation undefined

image-bbox

Bounding box of <image> subject to aspect-ratio preservation undefined

State:

OPEN

Product:

SVG 2

Raised by:

Cameron McCormack

Opened on:

2008-07-18

Description:

The spec doesn't really define what the bounding box of an <image> is. The non-obvious case is when preserveAspectRatio="" is set so that the image doesn't take up the whole area specified on the <image> element.

Test:

http://dev.w3.org/SVG/profiles/1.1F2/ua-tests/image-bbox.svg

In Firefox 3 and Opera 9.5, the bounding box is [0,0,400,400]. In Batik 1.7, it's [100,0,200,400]. I suppose I would prefer the latter, since it lets you determine the aspect ratio of the image from script.
