DOMMatrixReadOnly

package js.html

extended by DOMMatrix

Available on js

The DOMMatrixReadOnly interface represents 4x4 matrices, suitable for 2D and 3D operations. If this interface defines only read-only matrices, the DOMMatrix interface which inherits from it, add all the properties and the methods to allow to have modifiable matrices.

Variables

read onlya:Float

Are double representing each component of a 4x4 matrix needed for 2D rotations and translations. They are aliases for some components of the 4x4 matrix:

	<tr>
		2D
		3D equivalent
	</tr>


	<tr>
		<td><code>a</code></td>
		<td><code>m11</code></td>
	</tr>
	<tr>
		<td><code>b</code></td>
		<td><code>m12</code></td>
	</tr>
	<tr>
		<td><code>c</code></td>
		<td><code>m21</code></td>
	</tr>
	<tr>
		<td><code>d</code></td>
		<td><code>m22</code></td>
	</tr>
	<tr>
		<td><code>e</code></td>
		<td><code>m41</code></td>
	</tr>
	<tr>
		<td><code>f</code></td>
		<td><code>m42</code></td>
	</tr>

They are read-only, but their counterpart, with the same name, in DOMMatrix aren't.

read onlyis2D:Bool

Is a Boolean indicating if the matrix contains a 2D matrix and only accept 2D transformations.

Methods

flipX():DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the original matrix being flipped around the x-axis, that is multiplied by the DOMMatrix(-1, 0, 0, 1, 0, 0). The original matrix is not modified.

flipY():DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the original matrix being flipped around the y-axis, that is multiplied by the DOMMatrix(1, 0, 0, -1, 0, 0). The original matrix is not modified.

inverse():DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the original matrix being inverted. The original matrix is not modified. If the matrix cannot be inverted, all its components are set to NaN and is2D() returns false.

multiply(other:DOMMatrix):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the original matrix being multiplied by the given DOMMatrix. The original matrix is not modified.

rotate(angle:Float, originX:Float = 0.0, originY:Float = 0.0):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the original matrix being rotated by the given angle, with the rotation centered on the origin given. The original matrix is not modified.

rotateAxisAngle(x:Float, y:Float, z:Float, angle:Float):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the original matrix being rotated by the given angle and the given vector. The original matrix is not modified.

rotateFromVector(x:Float, y:Float):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the original matrix being rotated by the angle between the given vector and (1,0), centered on the origin given. The original matrix is not modified.

scale(scale:Float, originX:Float = 0.0, originY:Float = 0.0):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the matrix x and y dimensions being scaled by the given factor, centered on the origin given. The original matrix is not modified.

scale3d(scale:Float, originX:Float = 0.0, originY:Float = 0.0, originZ:Float = 0.0):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the matrix x, y and z dimension being scaled by the given factor, centered on the origin given. The original matrix is not modified.

scaleNonUniform(scaleX:Float, scaleY:Float = 1.0, scaleZ:Float = 1.0, originX:Float = 0.0, originY:Float = 0.0, originZ:Float = 0.0):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the matrix x, y and z dimension being scaled by the given factor for each dimension, centered on the origin given. The original matrix is not modified.

skewX(sx:Float):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the original matrix being skewed along the x-axis by the given factor. The original matrix is not modified.

skewY(sy:Float):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the original matrix being skewed along the y-axis by the given factor. The original matrix is not modified.

toFloat32Array():Float32Array

Returns a Float32Array containing the 6 components (a, b, c, d, e, f) in the case of a 2D matrix or the 16 components (m11, m12, m13, m14, m21, m22, m23, m24, m31, m32, m33, m34, m41, m42, m43, m44) for a 3D matrix.

Throws:

null

DOMError

toFloat64Array():Float64Array

Returns a Float64Array containing the 6 components (a, b, c, d, e, f) in the case of a 2D matrix or the 16 components (m11, m12, m13, m14, m21, m22, m23, m24, m31, m32, m33, m34, m41, m42, m43, m44) for a 3D matrix.

Throws:

null

DOMError

toJSON():Dynamic

Returns a JSON representation of the DOMMatrixReadOnly object.

transformPoint(?point:Null<DOMPointInit>):DOMPoint

Returns a DOMPoint that is the point given in parameter multiplied by the matrix. But the original point and the matrix aren't modified.

translate(tx:Float, ty:Float, tz:Float = 0.0):DOMMatrix

Returns a DOMMatrix containing a new matrix being the result of the matrix being translated by the given vector. The original matrix is not modified.
