,$pixels
Imports pixels from an array into an image. The map
is usually 'RGB'. This method imposes the following constraints for the parameters: amount of pixels in the array must match width
x height
x length of the map. Este método estará disponível se a extensão Imagick tiver sido compilada com a ImageMagick versão 6.4.5 ou superior.
x
The image x position
y
The image y position
width
The image width
height
The image height
map
Map of pixel ordering as a string. This can be for example RGB
. The value can be any combination or order of R = red, G = green, B = blue, A = alpha (0 is transparent), O = opacity (0 is opaque), C = cyan, Y = yellow, M = magenta, K = black, I = intensity (for grayscale), P = pad.
storage
The pixel storage method. Refer to this list of pixel constants.
pixels
The array of pixels
Retorna true

Exemplo #1 Imagick::importImagePixels() example
<?php
$count = 2000 * 3;
$pixels =
array_merge(array_pad(array(), $count, 0),
array_pad(array(), $count, 255),
array_pad(array(), $count, 0),
array_pad(array(), $count, 255),
array_pad(array(), $count, 0));
$width = $height = pow((count($pixels) / 3), 0.5);
$im = new Imagick();
$im->newImage($width, $height, 'gray');
$im->importImagePixels(0, 0, $width, $height, "RGB", Imagick::PIXEL_CHAR, $pixels);
$im->setImageFormat('jpg');
header("Content-Type: image/jpg");
echo $im;
