Object oriented style (method):
SYNOPSIS
public void CairoMatrix::scale (float $sx, float $sy)
DESCRIPTION
Procedural style:
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.
PARAMETERS
o $matrix
- Procedural only - CairoMatrix instance
o $sx
- scale factor in the X direction
o $sy
- scale factor in the Y direction
EXAMPLES
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);
?>
