CairoMatrix::scale -- cairo_matrix_scale — Applies scaling to a matrix

### Description

Object oriented style (method):

public void CairoMatrix::scale ( float `$sx` , float `$sy` )

Procedural style:

void cairo_matrix_scale ( CairoContext `$context` , float `$sx` , float `$sy` )

Applies scaling by sx, sy to the transformation in the matrix. The effect of the new transformation is to first scale the coordinates by sx and sy, then apply the original transformation to the coordinates.

### Parameters

`matrix`

  Procedural only - CairoMatrix instance

`sx`

  scale factor in the X direction

`sy`

  scale factor in the Y direction

### Examples

Example #1 Object oriented style

`<?php
/* Apply scaling to a matrix */
$matrix = new CairoMatrix(1.0, 0.5, 0.0, 1.0, 0.0, 0.0);
$matrix->scale(0.2, 2.0);
?>`

Example #2 Procedural style

`<?php
/* Apply scaling to a matrix */
$matrix = cairo_matrix_init(1.0, 0.5, 0.0, 1.0, 0.0, 0.0);
cairo_matrix_scale($matrix, 0.2, 2.0);
?>`
