オブジェクト指向型 (method):

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

手続き型:

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.

パラメータ

matrix

Procedural only - CairoMatrix instance

sx

scale factor in the X direction

sy

scale factor in the Y direction

例1 オブジェクト指向型

<?php
/* Apply scaling to a matrix */
$matrix = new CairoMatrix(1.00.50.01.00.00.0);
$matrix->scale(0.22.0);
?>

例2 手続き型

<?php
/* Apply scaling to a matrix */
$matrix cairo_matrix_init(1.00.50.01.00.00.0);
cairo_matrix_scale($matrix0.22.0);
