(PECL imagick 2 >= 2.3.0, PECL imagick 3)

Imagick::importImagePixelsImports image pixels

Description

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. This method is available if Imagick has been compiled against ImageMagick version 6.4.5 or newer.

Parameters

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

Return Values

Returns true on success.

Errors/Exceptions

Throws ImagickException on error.

Examples

Example #1 Imagick::importImagePixels() example

<?php/* 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, $pixels);/* output as jpeg image */$im->setImageFormat('jpg');header("Content-Type: image/jpg");echo $im;?>
