Imagick::exportImagePixels — Exports raw image pixels

### Description

public Imagick::exportImagePixels(
int `$x`,
int `$y`,
int `$width`,
int `$height`,
string `$map`,
int `$STORAGE`
): array

Exports image pixels into an array. The map defines the ordering of the exported pixels. The size of the returned array is `width * height * strlen(map)`. This method is available if Imagick has been compiled against ImageMagick version 6.4.7 or newer.

### Parameters

`x`

  X-coordinate of the exported area

`y`

  Y-coordinate of the exported area

`width`

  Width of the exported aread

`height`

  Height of the exported area

`map`

  Ordering of the exported pixels. For example `"RGB"`. Valid characters for the map are R, G, B, A, O, C, Y, M, K, I and P.

`STORAGE`

  Refer to this list of pixel type constants

### Return Values

Returns an array containing the pixels values.

### Errors/Exceptions

Throws ImagickException on error.

### Examples

Example #1 Using Imagick::exportImagePixels()

Export image pixels into an array

`<?php
/* Create new object */
$im = new Imagick();
/* Create new image */
$im->newPseudoImage(0, 0, "magick:rose");
/* Export the image pixels */
$pixels = $im->exportImagePixels(10, 10, 2, 2, "RGB", Imagick::PIXEL_CHAR);
/* Output */
var_dump($pixels);
?>`

The above example will output:

    array(12) {
      [0]=>
      int(72)
      [1]=>
      int(64)
      [2]=>
      int(57)
      [3]=>
      int(69)
      [4]=>
      int(59)
      [5]=>
      int(43)
      [6]=>
      int(124)
      [7]=>
      int(120)
      [8]=>
      int(-96)
      [9]=>
      int(91)
      [10]=>
      int(84)
      [11]=>
      int(111)
