Examples
Example #1 ImagickDraw::affine() example
<?php
function affine($strokeColor, $fillColor, $backgroundColor) {
$draw = new \ImagickDraw();
$draw->setStrokeWidth(1);
$draw->setStrokeOpacity(1);
$draw->setStrokeColor($strokeColor);
$draw->setFillColor($fillColor);
$draw->setStrokeWidth(2);
$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
