Imagick::importImagePixelsImports image pixels

Descrição

public bool Imagick::importImagePixels ( int $x , int $y , int $width , int $height , string $map , int $storage , array $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 está disponível se o PHP foi compilado com o ImageMagick versão 6.4.5 ou superior.

Parâmetros

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

Valor Retornado

Retorna TRUE no sucesso.

Erros

Lança ImagickException em caso de erro.

Exemplo #1 Imagick::importImagePixels() example

<?php

/* Generate array of pixels. 2000 pixels per color stripe */
$count 2000 3;

$pixels 
   
array_merge(array_pad(array(), $count0),
               
array_pad(array(), $count255), 
               
array_pad(array(), $count0),
               
array_pad(array(), $count255),
               
array_pad(array(), $count0));

/* 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) */
$im->importImagePixels(00$width$height"RGB"Imagick::PIXEL_CHAR$pixels);

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