How to create curved text with PHP Imagick?

How can curved text be obtained using Imagick (PHP)? I did not expect not to find a straightforward method or group of methods for this, but it happened...

I did find ImageMagick commands to obtain curved text (http://www.imagemagick.org/Usage/fonts/#arch), but I'm in need for an Imagick (PECL extension) -based script.

If you just want it curved, there is a demo here with the code below.

$draw = new \ImagickDraw();

$draw->setFont("../fonts/Arial.ttf");
$draw->setFontSize(48);
$draw->setStrokeAntialias(true);
$draw->setTextAntialias(true);
$draw->setFillColor('#ff0000');

$textOnly = new \Imagick();
$textOnly->newImage(600, 300, "rgb(230, 230, 230)");
$textOnly->setImageFormat('png');
$textOnly->annotateImage($draw, 30, 40, 0, 'Your Text Here');
$textOnly->trimImage(0);
$textOnly->setImagePage($textOnly->getimageWidth(), $textOnly->getimageheight(), 0, 0);

$distort = array(180);
$textOnly->setImageVirtualPixelMethod(Imagick::VIRTUALPIXELMETHOD_TRANSPARENT);

$textOnly->setImageMatte(true);
$textOnly->distortImage(Imagick::DISTORTION_ARC, $distort, false);

$textOnly->setformat('png');

header("Content-Type: image/png");
echo $textOnly->getimageblob();

If you actually want it along a path, then I don't think you can in Imagick. You would need to create an SVG file and convert that to a PNG and overlay it on an image Example of a textpath taken from https://developer.mozilla.org/en/docs/Web/SVG/Element/textPath 

<svg width="100%" height="100%" viewBox="0 0 1000 300"
     xmlns="http://www.w3.org/2000/svg" 
     xmlns:xlink="http://www.w3.org/1999/xlink">
  <defs>
    <path id="MyPath"
          d="M 100 200 
             C 200 100 300   0 400 100
             C 500 200 600 300 700 200
             C 800 100 900 100 900 100" />
  </defs>

  <use xlink:href="#MyPath" fill="none" stroke="red"  />

  <text font-family="Verdana" font-size="42.5">
    <textPath xlink:href="#MyPath">
      We go up, then we go down, then up again
    </textPath>
  </text>

  <!-- Show outline of the viewport using 'rect' element -->
  <rect x="1" y="1" width="998" height="298"
        fill="none" stroke="black" stroke-width="2" />
</svg>

which also needs an SVG converter that supports textpath. The one built into ImageMagick does not support textpath apparently.

According to my knowledge there is not direct method for creating curved text, but you can do by following procedure.

$draw = new ImagickDraw();
$draw->setFont('Sans.ttf');
$draw->setFontSize(20);
$draw->setStrokeAntialias(true);
$draw->setTextAntialias(true);
$draw->setFillColor('#ff0000');


$text = new Imagick();
$text->newImage(300, 300, "red");
$text->setImageFormat('png');
$text->annotateImage($draw, 30, 40, 0, 'Jitendra Kumar');

$text->trimImage(0);

$text->setImagePage($text->getimageWidth(), $text->getimageheight(), 0, 0);

$distortPoints = array( 120 );
$text->setImageVirtualPixelMethod( Imagick::VIRTUALPIXELMETHOD_TRANSPARENT);


$text->setImageMatte( TRUE );
$text->distortImage(Imagick::DISTORTION_ARC, $distortPoints, FALSE);

$text->setformat('png');

header("Content-Type: image/png");
echo $text->getimageblob();

Once your problem not solved let me know.
