Closed Bug 70978 Opened 21 years ago Closed 14 years ago
An OBJECT with exactly one of width or height given should be scaled proportionally
Let us assume, for example, I have a web page where I have embedded an SVG using the Object tag. If I do not specify width or height for an object, it should use it's natural size if it has one, else the default [240x200 in Moz]. If I specify only the width - to be say 75%, and not the height - the object width should be scaled to 75% of the available space, and the height should be scaled accordingly - to maintain perspective. Also, if you specify only one of width or height for an object using the default size [no natural size], then the unspecified dimension should also be scaled to maintain perspective. Specifying a height as 1em can be taken as a hint the author probably wouldn't want a 240px default width or vice versa.

Reopening. This affects more than plugins.
I suspect that the work in 70976 will cover all instances related to the object element. Peter: is it necessary for you to have both bugs open?
sounds like a dup of bug 70976 to me: SVG can't tell the browser its "natural size" if the NPAPI doesn't support it and hence layout has nothing to work with. Please attach a testcase showing how this effects more than just plugins otherwise close as dup.
An object having an intrinsic size has historically been orthogonal to Mozilla dealing with it correctly. Mozilla exhibits different behavior depending on the type of object being included, irregardless of whether that object has an intrinsic size. For example, I filed bug 69270 because image objects wouldn't size at all using percentages, let alone maintaining perspective while doing so, and images have always had an intrinsic size. That is why I marked bug 70976 as blocking this, so that when someone does add intrinsic sizing support for plugins, they will see this and also hopefully make sure the scaling works properly - which has definitely /not/ been a given, historically.

Summary: An OBJECT scaled using width /OR/ height should maintain perspective → An OBJECT with exactly one of width or height given should be scaled proportionally
I believe the behavior I am asking for in this bug report is specified in section 10.6.2 of the CSS 2.1 draft at: http://www.w3.org/TR/2006/WD-CSS21-20060411/visudet.html#inline-replaced-height Re: "block-level replaced elements in normal flow": If 'height' has a computed value of 'auto' and 'width' has some other computed value, and the replaced element has an intrinsic ratio, ... then the used value of 'height' is: (used width) / (intrinsic ratio)".
Whiteboard: [Hixie-P2] → [Hixie-P2][CSS1-5.5.23][CSS2.1-10.6.2]
This was fixed by bug 294086. Note that the testcases may not behave quite as you expect since you are required to specify a viewBox attribute if you want them to scale.
Absolutely fantastic! I think with Firefox 3 it's finally nearing time to have another attempt at using SVG on some intranet sites (bug 231179 now being the only major remaining caveat for me)! Thanks to you and all the Mozilla devs for your hard work! :)
You're welcome. Have fun. :) Hopefully we'll get that SVG "as an image" thing in the next release!
Tons of reftests were added as part of bug 294086. For the issue covered by this bug in particular see the object--* tests in: http://lxr.mozilla.org/seamonkey/source/layout/reftests/svg/sizing/
