This no longer uses the fill color.  It now uses the stroke color, consistent with the documentation.

point($x, $y) uses the FillColor of ImagickDraw! This actually took quite a while, till I found out that it's falsely documented on these pages. So to draw single pixels, do it like this:

<?php
$image
= new Imagick();
$draw = new ImagickDraw();
$pixel = new ImagickPixel('red');
$image->newImage(10, 10, 'transparent', 'gif');

// Here comes the magick:
$pixel->setColor($_POST[$i."x".$j]);
$draw->setFillColor($pixel);
$draw->point($i,$j);

$image->drawImage($draw);
$image->writeImages($path, true);
?>
