(PECL cairo >= 0.1.0)

CairoMatrix::scale -- cairo_matrix_scaleApplies scaling to a matrix

Beschreibung

Objektorientierter Stil (method):

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

Prozeduraler Stil:

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.

Parameter-Liste

`matrix`

Procedural only - CairoMatrix instance

`sx`

scale factor in the X direction

`sy`

scale factor in the Y direction

Beispiele

Beispiel #1 Objektorientierter Stil

``` <?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);?> ```

Beispiel #2 Prozeduraler Stil

``` <?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);?> ```
