示例1: affine
function affine($strokeColor, $fillColor, $backgroundColor)
{
$draw = new \ImagickDraw();
$draw->setStrokeWidth(1);
$draw->setStrokeOpacity(1);
$draw->setStrokeColor($strokeColor);
$draw->setFillColor($fillColor);

$PI = 3.141592653589794;
$angle = 60 * $PI / 360;
//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
//produces incorrectly scaled drawings.
$affineRotate = array("sx" => cos($angle), "sy" => cos($angle), "rx" => sin($angle), "ry" => -sin($angle), "tx" => 0, "ty" => 0);
//Translate (offset) the drawing
$affineTranslate = array("sx" => 1, "sy" => 1, "rx" => 0, "ry" => 0, "tx" => 30, "ty" => 30);
//The identiy affine matrix
$affineIdentity = array("sx" => 1, "sy" => 1, "rx" => 0, "ry" => 0, "tx" => 0, "ty" => 0);
$examples = [$affineScale, $affineShear, $affineRotate, $affineTranslate, $affineIdentity];

//Create an image object which the draw commands can be rendered into

//Render the draw commands in the ImagickDraw object
//into the image.
$image->drawImage($draw);
//Send the image to the browser
header("Content-Type: image/png");

}示例2: affineTransformImage

$draw = new ImagickDraw();
