imagejpg question

[badzv]

hi guys...got some questions regarding on my script....

[code]<?php

error_reporting(0);

$w = (int)$_POST['width'];
$h = (int)$_POST['height'];

$img = imagecreatetruecolor($w, $h);

imagefill($img, 0, 0, 0xFFFFFF);

$rows = 0;
$cols = 0;

for($rows = 0; $rows < $h; $rows++){

$c_row = explode(",", $_POST['px' . $rows]);
for($cols = 0; $cols < $w; $cols++){

$value = $c_row[$cols];

if($value != ""){

$hex = $value;
while(strlen($hex) < 6){
$hex = "0" . $hex;
}

$r = hexdec(substr($hex, 0, 2));
$g = hexdec(substr($hex, 2, 2));
$b = hexdec(substr($hex, 4, 2));

$test = imagecolorallocate($img, $r, $g, $b);

imagesetpixel($img, $cols, $rows, $test);
}
}
}

header("Content-type:image/jpeg");

imagejpeg($img, "", 95);

?>[/code]

...as you can see, the image comes from a POST variables. the problem here is that the image could be viewed but its not on the server. could somebody help me please how to make that image thats been generated with my php script to be on the server already? upon generated, it would be on the server already.

thank you very much!

anyone??? please!!!!!!!!!

Your question is not real clear.  By being on the server already do you mean save it to the server as a file?

If so, I got the following from HuggieBear in response to a question I posed.  This may not be the question you are asking.  If you are talking about how to get the image into a html page, well, I'm struggling with that also.

imagejpeg($im);
or

imagejpeg($im, null, 100);

By changing, or adding the second parameter, you can save the image.


$filename = '/home/domains/domain.co.uk/images/dynamic.jpg';
imagejpeg($im, $filename, 100);
