CairoMatrix::scale -- cairo_matrix_scale — Applies scaling to a matrix
Stile orientato agli oggetti (method):
$sx
, float $sy
)Stile procedurale:
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.
matrixProcedural only - CairoMatrix instance
sxscale factor in the X direction
syscale factor in the Y direction
Example #1 Stile orientato agli oggetti
<?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 Stile procedurale
<?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);
?>
