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);

?>
