Draw text with custom font using ImageMagick and PHP

Question

I want to dynamically render text to an image with a custom font, preferably with the option to output directly or save to a file. And to automatically set the image size according to the font/size combination.

I can already do this with GD, but it doesn't handle fonts where characters overlay each other.

So now I'm looking to ImageMagick. I've found an example in the docs that seem to do what I want. Is this possible with php_magick? Especially the part where no image size is defined :) If it is not, can I make command-line magick output the raw image, so I can pass it directly to the client with PHP?

Thanks!

The real question probably is: How do I convert the IM command below to PHP code using php_magick?

convert -background lightblue -fill blue -font Arial -pointsize 72 label:Anthony

You should be able to use the annotateImage function of the Imagick class to duplicate that functionality.

Here's a straight up copy-paste from that documentation:

<?php
/* Create some objects */
$image = new Imagick();
$draw = new ImagickDraw();
$pixel = new ImagickPixel( 'gray' );

/* New image */
$image->newImage(800, 75, $pixel);

/* Black text */
$draw->setFillColor('black');

/* Font properties */
$draw->setFont('Bookman-DemiItalic');
$draw->setFontSize( 30 );

/* Create text */
$image->annotateImage($draw, 10, 45, 0, 
    'The quick brown fox jumps over the lazy dog');

/* Give image a format */
$image->setImageFormat('png');

/* Output the image with headers */
header('Content-type: image/png');
echo $image;
