You can, but you haven't provided much information on the structure of your array. What I'd recommend using is the following;
Array $arr = (Array($x, $y, $r, $g, $b), Array($x, $y, $r, $g, $b) ...);
So you're looking at a multidimensional array, of which each embedded array is storing;
$x = x position of pixel
$y = y position of pixel
$r = red value (0 - 255)
$g = green value (0 - 255)
$b = blue value (0 - 255)
From here, you can use GD to draw the image.
In order to find the correct height and width of the picture, you'll want to define a function to compare the max x and y values, and update them based on the largest x/y values found in the array. i.e;
$max_height = (int) 0;
$max_width = (int) 0;
foreach ($arr as $a)
{
if ($a[0] > $max_width)
{
$max_width = $a[0];
}
if ($a[1] > $max_height)
{
$max_height = $a[1];
}
}
So, now you've got the max width and height for your image. From here, we can start constructing the image by running through the multidimensional array - basically, one pixel at a time.
To actually draw the pixel, we're going to use imagesetpixel.
$im = imagecreatetruecolor($width, $height);
foreach ($arr as $b)
{
$col = imagecolorallocate($im, $a[2], $a[3], $a[4]);
imagesetpixel ($im , $a[0] , $a[1] , $col );
}
Now, once we've finished, all that's left to do is actually display the image in the browser.
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
Hope this helps.
