当时我去了,但我最后去做的是数学清洗。 这一解决办法需要三个方面:

1. Include this script in your page (along with the SVGPan.js script), e.g.
   <script xlink:href="SVGPanUnscale.js"></script>
2. Identify the items you want not to scale (e.g. place them in a group with a special class or ID, or put a particular class on each element) and then tell the script how to find those items, e.g.
   unscaleEach("g.non-scaling > *, circle.non-scaling");
3. Use transform="translate(…,…)" to place each element on the diagram, not cx="…" cy="…".

仅仅采取这些步骤,使用SVGPan进行集聚和种植不会影响标记要素的规模(或轮换或sk)。

// Apply a translation to the element to have it remain at a local position

如果你寻找完全静态的方式,你可能能够将非中风与标记相结合,以达到这一目的,因为标识可能与中风。

换言之,你可以把圈子划入一个带;标记和组件,然后在需要时使用这些标识。

<svg width="500" height="500" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 2000 2000">
    <marker id="Triangle"
      viewBox="0 0 10 10" refX="0" refY="5" 
      markerUnits="strokeWidth"
      markerWidth="4" markerHeight="3"
      orient="auto">
      <path d="M 0 0 L 10 5 L 0 10 z" />
    </marker>
        <path d="M 100 100 l 200 0" vector-effect="non-scaling-stroke"
        fill="none" stroke="black" stroke-width="10" 
        marker-end="url(#Triangle)"  />
        <path d="M 100 200 l 200 0" 
        fill="none" stroke="black" stroke-width="10" 
        marker-end="url(#Triangle)"  />
</svg>

The same can also be viewed and tweaked here. The svg spec isn t fully explicit about what should happen in this case (since markers are not in SVG Tiny 1.2, and vector-effect isn t in SVG 1.1). My current line of thinking was that it should probably affect the size of the marker, but it seems no viewers do that at the moment (try in a viewer that supports vector-effect, e.g Opera or Chrome).

类似一些工作是在网上进行的(可能与这一ug子有关:320635 <);以及新变式的贴在仅仅照此附上时的 t。

transform.baseVal.appendItem

function unscale()
{
    var xf = this.ownerSVGElement.createSVGTransform();
    var m = this.ownerSVGElement.getTransformToElement(this.parentNode);
    m.e = m.f = 0; // Ignore (preserve) any translations done up to this point
    xf.setMatrix(m);

    // Keep a single transform matrix in the stack for fighting transformations
    // Be sure to apply this transform after existing transforms (translate)
    var SVG_TRANSFORM_MATRIX = 1;
    var SVG_TRANSFORM_TRANSLATE = 2;
    var baseVal = this.transform.baseVal;
    if(baseVal.numberOfItems == 0)
        baseVal.appendItem(xf);
    else
    {
        for(var i = 0; i < baseVal.numberOfItems; ++i)
        {
            if(baseVal.getItem(i).type == SVG_TRANSFORM_TRANSLATE && i == baseVal.numberOfItems - 1)
        {
                baseVal.appendItem(xf);
            }

            if(baseVal.getItem(i).type != SVG_TRANSFORM_TRANSLATE)
            {
                if(baseVal.getItem(i).type == SVG_TRANSFORM_MATRIX)
                    baseVal.replaceItem(xf, i);
                else
                    baseVal.insertItemBefore(xf, i);
                break;
            }
        }
    }
}

var m = this.parentNode.getScreenCTM().inverse().multiply(this.ownerSVGElement.getScreenCTM());

会议讨论了here和。
