[SOLVED] imagecreatefrompng don't work

[tivrfoa]

Hi!

 

the following code doesn't working:

 

<?php

header("Content-type: image/png");
$string = $_GET['text'];
$im     = imagecreatefrompng("images/button1.png");
$orange = imagecolorallocate($im, 220, 210, 60);
$px     = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 3, $px, 9, $string, $orange);
imagepng($im);
imagedestroy($im);

?>

 

I just copy and pasted it: http://php.net/manual/en/image.examples-png.php

 

I created the folder images and added an image with the name "button1.png" and I'm passing the text parameter "php?text=text", but the page only display this: http://localhost/path/file.php?text=text

Note, localhost is local to your computer. We cannot see that.

 

Copy what it displays, make sure you have the GD library installed. If it is an image that is displaying on the localhost take a screenshot and post it here.

i'm not that newbie  .

 

I think gd is installed, because I can create images, but not from png file.

eg:

 

<?php
function LoadPNG($imgname)
{
    /* Attempt to open */
    $im = @imagecreatefrompng($imgname);

    /* See if it failed */
    if(!$im)
    {
        /* Create a blank image */
        $im  = imagecreatetruecolor(150, 30);
        $bgc = imagecolorallocate($im, 255, 255, 255);
        $tc  = imagecolorallocate($im, 0, 0, 0);

        imagefilledrectangle($im, 0, 0, 150, 30, $bgc);

        /* Output an error message */
        imagestring($im, 1, 5, 5, 'Error loading ' . $imgname, $tc);
    }

    return $im;
}

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

$img = LoadPNG('bogus.image');

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

 

this code enter in the "if", because it fails in create the image from the png file.

Well why did you link to it then? lol.

 

Anywho, i'm confused. Bogus.image obviously isn't a png image. So surely the script is performing correctly?

Do a phpinfo I bet you that PNG Support is not enabled.

 

And as far as my statement, sorry to implicate that, but you linking to it saying "It only displays this" sounded to me like you expect us to be able to click on it and see what you mean.

I didn't put the link to you access. I just write what displayed in the page, but as it start with "http:" it created the link automatically!

Sounds like you got some other issues, maybe with Apache....I do not know why it would show the url inside the page... ???

 

Anyhow did you checkout the phpinfo?

[tivrfoa]

phpinfo();

I'm using IIS (not by my will). Maybe some access property, anyone?

Mmm, thats a pitty. I do not use IIS, I tested your script on my apache server and it worked like a champ....but I was using a 284x156 button1.png image, whether that has something to do with it I do not know.

[tivrfoa]

I created some images in paint and saved as png, and it's all working fine.

I was using some images that I saved as png from the Internet. 

 

thanks very much premiso
