Imagick::importImagePixelsImports image pixels


public Imagick::importImagePixels(
    int $x,
    int $y,
    int $width,
    int $height,
    string $map,
    int $storage,
    array $pixels
): bool

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.



The image x position


The image y position


The image width


The image height


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.


The pixel storage method. Refer to this list of pixel constants.


The array of pixels

Exemplo #1 Imagick::importImagePixels() example


/* Generate array of pixels. 2000 pixels per color stripe */
$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 and height. The area is amount of pixels divided
by three. Three comes from 'RGB', three values per pixel */
$width = $height = pow((count($pixels) / 3), 0.5);

/* Create empty image */
$im = new Imagick();
$im->newImage($width, $height, 'gray');

/* Import the pixels into image.
width * height * strlen("RGB") must match count($pixels) */
$im->importImagePixels(0, 0, $width, $height, "RGB", Imagick::PIXEL_CHAR, $pixels);

/* output as jpeg image */
header("Content-Type: image/jpg");
