范例

Example #1 ImagickDraw::point()

<?php
function point($fillColor, $backgroundColor) {
    $draw = new \ImagickDraw();
    $draw->setFillColor($fillColor);
    for ($x = 0; $x < 10000; $x++) {
        $draw->point(rand(0, 500), rand(0, 500));
    }
    $imagick = new \Imagick();
    $imagick->newImage(500, 500, $backgroundColor);
    $imagick->setImageFormat("png");
    $imagick->drawImage($draw);
    header("Content-Type: image/png");
    echo $imagick->getImageBlob();
}
?>

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);
?>
