CairoMatrix::scale -- cairo_matrix_scale — Applies scaling to a matrix
Object oriented style (method):
$sx
, float $sy
) : voidProcedural 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.
matrixProcedural only - CairoMatrix instance
sxscale factor in the X direction
syscale 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);
?>
