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

˵��

��������� (method):

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

���̻����:

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

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.

����

matrix

Procedural only - CairoMatrix instance

sx

scale factor in the X direction

sy

scale factor in the Y direction

Example #1 ���������

<?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 ���̻����

<?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);
?>
