范例

Example #1 Imagick::textureImage()

<?php
function textureImage($imagePath) {
    $image = new \Imagick();
    $image->newImage(640, 480, new \ImagickPixel('pink'));
    $image->setImageFormat("jpg");
    $texture = new \Imagick(realpath($imagePath));
    $texture->scaleimage($image->getimagewidth() / 4, $image->getimageheight() / 4);
    $image = $image->textureImage($texture);
    header("Content-Type: image/jpg");
    echo $image;
}
?>

This method doesn't actually return TRUE on success, it returns an Imagick with the texture applied, but the original Imagick object is not modified. As per the other examples on here, you need to use the result of textureImage call as your new tiled image.

<?php
$image = new Imagick();
$image->newImage(500, 500, new ImagickPixel('red'));
$image->setImageFormat("png");
$type=$image->getFormat();
header("Content-type: $type");
$texture = new Imagick();
$texture->readImage('texture.png');
$image = $image->textureImage($texture);
echo $image;
?>
This works for me, however, I give no guarantees that the above example is the proper usage of this function.
