[RESOLVED] imagegif to file

[luiddog]

I'm using the following example and function. If -- header("Content-type: image/gif");-- is in the page without the Filename in imagegif it works fine. If I add the Filename to image gif it returns with just the URL and no file. If I take out -- header("Content-type: image/gif");-- and still have the Filename I get a blank page.

I've tried just the Filename and the Filename from the root. Still nothing.

I'm trying to make a hard copy of the image.

<?

///Example

$str = "test";   
$TC = array(255,255,255);
$BC = array(159, 180, 204);
imagegif(imagettfJustifytext($str,"assets/ARIALN.TTF",2, 64, 16,0,0,10,$TC,$BC), "test.gif");


///Function

function imagettfJustifytext($text, $font, $Justify, $W, $H, $X, $Y, $fsize, $color=array(0x0,0x0,0x0), $bgcolor=array(0xFF,0xFF,0xFF)){

    $angle = 0;
    $L_R_C = $Justify;
    $_bx = imageTTFBbox($fsize,0,$font,$text);

    $W = ($W==0)?abs($_bx[2]-$_bx[0]):$W; 
    $H = ($H==0)?abs($_bx[5]-$_bx[3]):$H; 

    $im = @imagecreate($W, $H)
        or die("Cannot Initialize new GD image stream");


    $background_color = imagecolorallocate($im, $bgcolor[0], $bgcolor[1], $bgcolor[2]);
    $text_color = imagecolorallocate($im, $color[0], $color[1], $color[2]);           

    if($L_R_C == 0){ //Justify Left

        imagettftext($im, $fsize, $angle, $X, $fsize, $text_color, $font, $text);

    }elseif($L_R_C == 1){ //Justify Right
        $s = split("[\n]+", $text);
        $__H=0;

        foreach($s as $key=>$val){

            $_b = imageTTFBbox($fsize,0,$font,$val);
            $_W = abs($_b[2]-$_b[0]);
            $_X = $W-$_W;
            $_H = abs($_b[5]-$_b[3]); 
            $__H += $_H;             
            imagettftext($im, $fsize, $angle, $_X, $__H, $text_color, $font, $val);   
            $__H += 6;

        }

    }
    elseif($L_R_C == 2){ //Justify Center

        $s = split("[\n]+", $text);
        $__H=0;

        foreach($s as $key=>$val){

            $_b = imageTTFBbox($fsize,0,$font,$val);
            $_W = abs($_b[2]-$_b[0]);
            $_X = abs($W/2)-abs($_W/2);
            $_H = abs($_b[5]-$_b[3]); 
            $__H += $_H;             
            imagettftext($im, $fsize, $angle, $_X, 12, $text_color, $font, $val);   
            $__H += 6;

        }

    }       

    return $im;

}

?>

I've also tried:

    $str = "test";   

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

	$TC = array(255,255,255);
	$BC = array(159, 180, 204);
    imagegif(imagettfJustifytext($str,"assets/ARIALN.TTF",2, 64, 16,0,0,10,$TC,$BC), "test.gif");

and:

    $str = "test";   

	$TC = array(255,255,255);
	$BC = array(159, 180, 204);
    imagegif(imagettfJustifytext($str,"assets/ARIALN.TTF",2, 64, 16,0,0,10,$TC,$BC), "subdomains/community/httpdocs/test.gif");

If you supply the second argument to imagegif(), then it writes its output to that file (on the server) instead of outputting it directly to the client. If you also want to output the image to the client, then you'll have to call imagegif() a second time without that filename argument.

[cahva]

If you are saving it to file, you have to output the file after creation:

...
imagegif(imagettfJustifytext($str,"assets/ARIALN.TTF",2, 64, 16,0,0,10,$TC,$BC), "test.gif");

readfile("test.gif"); // outputs the file
die(); // just to make sure that script doesnt output anything else eg. empty lines

[luiddog]

cahva, I tried your code but nothing. Do I need to put the root file location?
i.e. httpdocs/test.gif. I tried that too but nothing.

You need to put the correct path - whatever that may be for you.

Also note that the directory you're attempting to save this image file in must have permissions set so that the webserver can do so - comment out the readfile(), turn on display_errors, and set error_reporting to E_ALL to see if any errors are occurring. If so, they're most likely due to permissions issues.

The folder permission was it. Thanks.
