CairoMatrix::scale -- cairo_matrix_scale — Applies scaling to a matrix
Object oriented style (method):
$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.
matrix
Procedural only - CairoMatrix instance
sx
scale factor in the X direction
sy
scale factor in the Y direction
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);
?>
