Bug 308736 – Remove nearestViewportElement and farthestViewportElement from SVGGraphicsElement.idl

• Status: RESOLVED
• Resolution: FIXED
• Component: SVG

[Karl Dubost]

https://w3c.github.io/svgwg/svg2-draft/single-page.html#types-InterfaceSVGGraphicsElement

The IDL in SVG2 is defined by:

======================
dictionary SVGBoundingBoxOptions {
  boolean fill = true;
  boolean stroke = false;
  boolean markers = false;
  boolean clipped = false;
};

[Exposed=Window]
interface SVGGraphicsElement : SVGElement {
  [SameObject] readonly attribute SVGAnimatedTransformList transform;

  DOMRect getBBox(optional SVGBoundingBoxOptions options = {});
  DOMMatrix? getCTM();
  DOMMatrix? getScreenCTM();
};

SVGGraphicsElement includes SVGTests;
========================

WEBKIT. It's messy. See Bug 204038
===============
[
    Exposed=Window
] interface SVGGraphicsElement : SVGElement {
    [SameObject] readonly attribute SVGAnimatedTransformList transform;

    // FIXME: `getBBox` should return a `DOMRect`.
    // FIXME: `getBBox` should take an `optional SVGBoundingBoxOptions` as a parameter.
    [ImplementedAs=getBBoxForBindings, NewObject] SVGRect getBBox();
    // FIXME: `getCTM` should return a `DOMMatrix?`.
    [ImplementedAs=getCTMForBindings, NewObject] SVGMatrix? getCTM();
    // FIXME: `getScreenCTM` should return a `DOMMatrix?`.
    [ImplementedAs=getScreenCTMForBindings, NewObject] SVGMatrix? getScreenCTM();

    // Non-standard.
    // FIXME: These have been removed from SVG2.
    readonly attribute SVGElement? nearestViewportElement;
    readonly attribute SVGElement? farthestViewportElement;
};

GECKO
This has already been removed from Gecko.
https://searchfox.org/firefox-main/source/dom/webidl/SVGGraphicsElement.webidl

================
dictionary SVGBoundingBoxOptions {
  boolean fill = true;
  boolean stroke = false;
  boolean markers = false;
  boolean clipped = false;
};

[Exposed=Window]
interface SVGGraphicsElement : SVGElement {
  readonly attribute SVGAnimatedTransformList transform;

  [NewObject]
  SVGRect getBBox(optional SVGBoundingBoxOptions aOptions = {});
  SVGMatrix? getCTM();
  SVGMatrix? getScreenCTM();
};

SVGGraphicsElement includes SVGTests;
================



And it is still visible on Chromium
https://chromium.googlesource.com/chromium/blink/+/refs/heads/main/Source/core/svg/SVGGraphicsElement.idl

================
[
    TypeChecking=Interface,
] interface SVGGraphicsElement : SVGElement {
    [RuntimeEnabled=SVG1DOM, MeasureAs=SVG1DOM] readonly attribute SVGAnimatedTransformList transform;
    [MeasureAs=SVGLocatableNearestViewportElement] readonly attribute SVGElement nearestViewportElement;
    [MeasureAs=SVGLocatableFarthestViewportElement] readonly attribute SVGElement farthestViewportElement;
    [ImplementedAs=getBBoxFromJavascript] SVGRect getBBox();
    [ImplementedAs=getCTMFromJavascript] SVGMatrix getCTM();
    [ImplementedAs=getScreenCTMFromJavascript] SVGMatrix getScreenCTM();
    [RaisesException, MeasureAs=SVGGraphicsElementGetTransformToElement] SVGMatrix getTransformToElement(SVGElement element);
};
SVGGraphicsElement implements SVGTests;
================
