  • Difficulty Level : Easy
  • Last Updated : 20 Aug, 2019

The Imagick::affineTransformImage() function is an inbuilt function in PHP which is used to transform an image as dictated by the affine matrix.


bool Imagick::affineTransformImage( $matrix )

Parameters: This function accepts single parameter $matrix which holds the value of affine matrix either based on rotate, sheer, scale, etc, …

Return Value: This function returns True on success and FALSE on failure.

Below program illustrates the Imagick::affineTransformImage() function in PHP:

Program: This program uses Imagick::affineTransformImage() function to transforms an image by affine given affine matrix.

// Create an Imagick object
$imagick = new \Imagick(
// Create an ImagickDraw object
$imagickDraw = new \ImagickDraw();
// Set the angle
$theta = "35";
// Create affine transformation matrix
$affineRotate = array (
    "sx" => cos($theta), "sy" => cos($theta),
    "rx" => sin($theta), "ry" => -sin($theta),
    "tx" => 0, "ty" => 0,
// Use affine() function
// Set the image format
// Use affineImageFormat() function
header("Content-Type: image/png");
// Display the output image
echo $imagick->getImageBlob();
