png to svg conversion gives me below output:
<svg xmlns="http://www.w3.org/2000/svg" id="svg" version="1.1" width="963" height="694" x="0mm"><path id="svgpath" d="M488.000

In browser console:
var svgimg = document.getElementById("svg");
var val = svgimg.x.baseVal;
console.log(val);
This gives me below SVGLength object:
SVGLength {unitType: 7, value: 0, valueInSpecifiedUnits: 0, valueAsString: "0mm"}
unitType: 7
value: 2367.94482421875
valueAsString: "626.519mm"
valueInSpecifiedUnits: 626.5187377929688
__proto__: SVGLength
SVG_LENGTHTYPE_CM: 6
SVG_LENGTHTYPE_EMS: 3
SVG_LENGTHTYPE_EXS: 4
SVG_LENGTHTYPE_IN: 8
SVG_LENGTHTYPE_MM: 7
SVG_LENGTHTYPE_NUMBER: 1
SVG_LENGTHTYPE_PC: 10
SVG_LENGTHTYPE_PERCENTAGE: 2
SVG_LENGTHTYPE_PT: 9
SVG_LENGTHTYPE_PX: 5
This calculation tell me that length of the line in image is 626.519mm which is not correct. it's 100mm in length.
My question is : Is this calculation correct? if yes, then what area it covers for calculation ? if this calculation is correct then what should the correct calculation to calculate the svg path length in unit mm or cm ?
var myPath = document.getElementById("svgpath");
var length = myPath.getTotalLength();
console.log(length);
this length doesn't gives me length in desired unit. it only gives me some number which doesn't have any unit associated with it.
