  currently i have two files

 

  1) workingscript.html --> html form

  2) redirection.php --> page where the created (png) file is displayed on the browser...

 

  problem (@ redirection.php): when i try to save the created image (png) file in my hard disk (right click > save picture as) ....i cannot to preview/open the png file that i just earlier saved in my hard disk

 

     

      See  figure_1.jpg                  

              output png image at redirection.php

               

        See figure_2.jpg  

              Saving the image as outputPNGImage.png in my hard disk

 

      See figure_3.jpg         

              There was an error displaying outputPNGImage.png that was just earlier saved in my hard disk

 

anyway, here's my code

 

1) workingscript.html

 

 

<html>
<head>


<SCRIPT LANGUAGE="JavaScript">

function textCounter(field, countfield, maxlimit) {
if (field.value.length > maxlimit) // if too long...trim it!
field.value = field.value.substring(0, maxlimit);

else 
countfield.value = maxlimit - field.value.length;
}

</script>

thanks but it didn't work....(i simply copied and paste the php code you gave and made no modifications...or should i modify it in one way or another)

 

btw, here's the a part of a php code (iart.php) that i got from a site that enabled me to saved the created image....i believe that this code just simply displays the created image  (i just don't know how to modify it to suit my php code)..hehe..sorry..php newbie here...

 

 

<p>
	<h1><?php echo $TEXT['iart-head']; ?></h1>

	<img width="520" height="320" src="iart.php?img=1&text=<?=urlencode($text)?>" alt=""><p class="small">
	<?=$TEXT['iart-text1']?><p>

 

 

full source for code iart.php

 

<?php



		$text=$_REQUEST['text'];
        if($text=="") $text="";
        if($_REQUEST['img']!=1)
        {
?>
<html>
<head>
	<meta name="author" content="Kai Oswald Seidler">
	<link href="xampp.css" rel="stylesheet" type="text/css">
	<title></title>
</head>

<body>
	 <p>
	<h1> </h1>

<img width="520" height="320" src="iart.php?img=1&text=<?=urlencode($text)?>" alt="">
	<p class="small">
    
<p>
	<form name="ff" action="iart.php" method="get">
		<input type="text" name="text" size="30">
		<input type="submit" value="Submit">
	</form>
	<p>
    
</body>
</html>
<?php
	exit;
}

$fontfile = "./AnkeCalligraph.TTF";

$size = 9;
$h = 320;
$w = 520;

$im  =  ImageCreate($w, $h);

$fill = ImageColorAllocate($im, 251, 121, 34);
$light = ImageColorAllocate($im, 255, 255, 255);
$corners = ImageColorAllocate($im, 153, 153, 102);
$dark = ImageColorAllocate($im, 51, 51 , 0);
$black = ImageColorAllocate($im , 0, 0 , 0);

$colors[1] = ImageColorAllocate($im, 255, 255, 255);
$colors[2] = ImageColorAllocate($im, 255 * 0.95, 255 * 0.95, 255 * 0.95);
$colors[3] = ImageColorAllocate($im, 255 * 0.9, 255 * 0.9, 255 * 0.9);
$colors[4] = ImageColorAllocate($im, 255 * 0.85, 255 * 0.85, 255 * 0.85);

header("Content-Type: image/png");

srand(time());

$c = 1;
$anz = 10;
$step = (4 / $anz);
for ($i = 0; $i < $anz; $i += 1) {
	$size = rand(7, 70);
	$x = rand(-390, 390);
	$y = rand(-100, 400);
	$color = $colors[$c];
	$c += $step;
	ImageTTFText($im, $size, 0, $x, $y, $color, $fontfile, $_GET['text']);
}

ImageLine($im, 0, 0, $w - 1, 0, $light);
ImageLine($im, 0, 0, 0, $h - 2, $light);
ImageLine($im, $w - 1, 0, $w-1, $h, $dark);
ImageLine($im, 0, $h - 1, $w - 1, $h - 1, $dark);
ImageSetPixel($im, 0 , $h - 1, $corners);
ImageSetPixel($im, $w - 1, 0, $corners);

ImagePNG($im);
exit;
?>

 

so basically, that's the code that i got from a certain site that allows the users to create their own "interactive text art" image and enables them to save it on their local hard disk

 

i just don't know how incorporate/modify the php code in my script so the users can also save the created image in my php file...

 

tnx for reply guys, i'm really learning here!!!

you can not output html into the image..

 

you need to use a php script in replacement of an image BUT you still need to write the HTML to use it as an image ie

<?php
header("Content-type: image/png");

$name = $_GET['text']; # get value for name...

$im     = imagecreatefrompng("background.png");
$white = imagecolorallocate($im, 255, 255, 255);

#loads font 
   $font = "ariblk.ttf"; 

# this is for name
     imagettftext($im, 14, 0, 300, 315, $white, $font, $name);

imagepng($im);
imagedestroy($im);
?>

 

save that as image.php

 

now

the image to use that would be 

<img src="image.php?name=Hello">

If you want to save the image, shouldnt it be

 

imagepng($im,"test");

 

example of my old script

 

<?php
$im = imagecreate(100, 100);

// Get coordinates
$x1 = imagesx($im) / 2;
$y1 = imagesy($im) / 2 ;
// Shuffle
$green = rand(10,200);
$red = rand(50,200);
$blue = rand(20,200);
// sets background to red
$background = imagecolorallocate($im, 255, 0, 0);
$green      = imagecolorallocate($im,$green,$red,$blue); 
$red      = imagecolorallocate($im,$green,$red,$blue); 

// Set text color
$text    = imagecolorallocate($im,0,0,110);
// Set a string
$string = imagestring($im,5,10,45,"H e l l o",$text);
// line
$line   = imageline($im,0,10,100,100,$green);
$line   = imageline($im,0,$green,10,100,$red);
// allocate some colors
$white2 = imagecolorallocate($im, 255, 255, 255);
$red2   = imagecolorallocate($im, 255,   0,   0);
$green2 = imagecolorallocate($im,   0, 255,   0);
$blue2  = imagecolorallocate($im,   0,   0, 255);

// draw the head
imagearc($im, 100, 100, 200, 200,  0, 360, $white2);
// mouth
imagearc($im, 100, 100, 150, 150, 25, 155, $red2);
// left and then the right eye
imagearc($im,  60,  75,  50,  50,  0, 360, $green2);
imagearc($im, 140,  75,  50,  50,  0, 360, $blue2);


imagepng($im,"testing",9);
?>

 

 

 

edit: NVM, lol, I didnt read the "imagecreatefrompng" part.
