示例 #1 ImagickDraw::affine() example

<?php

$draw = new \ImagickDraw();

$draw->setStrokeWidth(1);
$draw->setStrokeOpacity(1);

//Scale the drawing co-ordinates.
$affineScale = array("sx" => 1.75, "sy" => 1.75, "rx" => 0, "ry" => 0, "tx" => 0, "ty" => 0);

//Shear the drawing co-ordinates.
$affineShear = array("sx" => 1, "sy" => 1, "rx" => sin($angle), "ry" => -sin($angle), "tx" => 0, "ty" => 0);

//Rotate the drawing co-ordinates. The shear affine matrix
