SVGAngle: convertToSpecifiedUnits() method

The convertToSpecifiedUnits() method of the SVGAngle interface allows you to convert the angle’s value to the specified unit type.

This function will:

• Set the unitType property to the given unit type
• Update the valueInSpecifiedUnits and valueAsString properties so the angle value is represented in the given unit type

Syntax

convertToSpecifiedUnits(unitType)

Parameters

• unitType
  • : A constant representing the unit type to which the angle’s value should be converted. This must be one of the constant values defined for the unitType property, with the exception of SVG_ANGLETYPE_UNKNOWN.
    • SVGAngle.SVG_ANGLETYPE_DEG: convert to degrees
    • SVGAngle.SVG_ANGLETYPE_RAD: convert to radians
    • SVGAngle.SVG_ANGLETYPE_GRAD: convert to gradians
    • SVGAngle.SVG_ANGLETYPE_UNSPECIFIED: convert to a unitless number, interpreted as degrees

Return value

None (undefined).

Examples

Converting an angle to degrees

// Get an SVGAngle object
const svg = document.querySelector("svg");
const angle = svg.createSVGAngle();

// Set the angle's value in radians (Math.PI / 2)
angle.newValueSpecifiedUnits(SVGAngle.SVG_ANGLETYPE_RAD, Math.PI / 2);

// Retrieve the angle's value as a string
console.log(angle.valueAsString); // Output: 1.5708rad
console.log(angle.unitType); // Output: 3 (SVG_ANGLETYPE_RAD)

// Convert the angle's value to degrees
angle.convertToSpecifiedUnits(SVGAngle.SVG_ANGLETYPE_DEG);

// Retrieve the angle's value as a string
console.log(angle.valueAsString); // Output: 90deg
console.log(angle.unitType); // Output: 2 (SVG_ANGLETYPE_DEG)
