CairoMatrix::scale
cairo_matrix_scale
(PECL cairo >= 0.1.0)
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:
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);
?>
