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);


?>
