Flipping an SVG vertically with scale causing a Geometry.scale:y error

We are reading our svg file to get the path string. Everything works great except the SVG images are upside down. I understand this is typical so that is not the issue. In angularjs service I have created I do the following steps to flip the SVG icon.

var geo = go.Geometry.parse(<iconString>, true); geo.scale(1, -1); geo.normalize();

The string I’m using to create the geo is as follows:
M632.571 449.714l-424-424q-10.857-10.857-25.714-10.857t-25.714 10.857l-94.857 94.857q-10.857 10.857-10.857 25.714t10.857 25.714l303.429 303.429-303.429 303.429q-10.857 10.857-10.857 25.714t10.857 25.714l94.857 94.857q10.857 10.857 25.714 10.857t25.714-10.857l424-424q10.857-10.857 10.857-25.714t-10.857-25.714z

What am I missing? Any help would be appreciated.
Thanks!

I just tried modifying the Icons sample, http://gojs.net/latest/samples/icons.html.

I added this line to try your geometry path string:

    icons["extra"] = "M632.571 449.714l-424-424q-10.857-10.857-25.714-10.857t-25.714 10.857l-94.857 94.857q-10.857 10.857-10.857 25.714t10.857 25.714l303.429 303.429-303.429 303.429q-10.857 10.857-10.857 25.714t10.857 25.714l94.857 94.857q10.857 10.857 25.714 10.857t25.714-10.857l424-424q10.857-10.857 10.857-25.714t-10.857-25.714z";

I changed the following code to use your code to modify the created Geometry:

    // "icons" is defined in icons.js
    // SVG paths have no flag for being filled or not, but GoJS Geometry paths do.
    // We want to mark each SVG path as filled:
    for (var k in icons) {
      var geo = go.Geometry.parse(icons[k], true);
      geo.scale(1, -1);
      geo.normalize();
      icons[k] = geo;
    }

And then I changed the binding to bind Shape.geometry rather than the Shape.geometryString:

        $(go.Shape,
          { margin: 3, fill: colors["white"], strokeWidth: 0 },
          new go.Binding("geometry", "geo", geoFunc)),

This produced the following results:

Isn’t that what you were expecting?

That is what I see if I comment out the scale code. The Icons are upside down. Sorry, I gave you a horrible path to test with as it was a chevron right… my fault.

this is a string for the info button that might be easier to see

When I comment out the scale I see this:

When I uncomment the scale I get the error. We were using version 1.4.27. My company just got me the newest version and it has fixed this issue…

Sorry for the waste of time. You can close this issue.

PS - thanks for the quick responses by the way
