SVGTransform: setMatrix() method

The setMatrix() method of the SVGTransform interface sets the transform type to SVG_TRANSFORM_MATRIX, with parameter matrix defining the new transformation.

Note that the values from the parameter matrix are copied, meaning changes to the matrix object after calling this method will not affect the transformation.

Syntax

setMatrix(matrix)

Parameters

matrix

A live DOMMatrix object defining the new transformation matrix to apply.

Return value

None (undefined).

Exceptions

NoModificationAllowedError DOMException

Thrown if the attribute or the SVGTransform object is read-only.

Examples

Setting a Transformation Matrix

// Get an SVG element and create a transform object
const svgElement = document.querySelector("svg");
const transform = svgElement.createSVGTransform();

// Create a DOMMatrix with specific values
const matrix = new DOMMatrix();
matrix.a = 1; // Scale X
matrix.d = 1; // Scale Y
matrix.e = 50; // Translate X
matrix.f = 50; // Translate Y

// Set the transform to the new matrix
transform.setMatrix(matrix);

console.dir(transform.matrix); // Output: SVGMatrix { a: 1, b: 0, c: 0, d: 1, e: 50, f: 50 }
