Hi,

I am having some problems related to GD and PHP. I am trying to create an image with GD library and PHP, but...

here is what happens:

If I run the code on my localhost




<?php
header ("Content-type: image/png");
$img_handle = ImageCreate (230, 20) or die ("Cannot Create image");
$back_color = ImageColorAllocate ($img_handle, 0, 10, 10);
$txt_color = ImageColorAllocate ($img_handle, 233, 114, 191);
ImageString ($img_handle, 31, 5, 5, "My first Program with GD", $txt_color);
ImagePng ($img_handle);
?>



Instead of showing a png file it prints wierd characters on the browser:

‰PNG  IHDRæ£þÓêPLTE ér¿`ŽLÚIDATxœåбAàŸMhF®!ža’+(„WÙË&ª;‘x?ë”Z…‡Ði'J­D£RÑ+®0wÁ¯`«ÙýòÏfø³Sc

CYeŸG?Eý˜õà«*T,(´ªšðñ£Peí|&H»;?&¦±éÖ³½54IÇ%¥öÉé¿×‘[¢•!‘i¡)1kg$;ÇP

Yes, it prints all this weird characters just as it is above. I know I have installed GD, because I checked it with the info() function:

<?php


echo "<xmp> ";

print_r(gd_info());


echo "</xmp> ";


?>



This prints:


Array
(
[GD Version] => bundled (2.0.28 compatible)
[FreeType Support] => 1
[FreeType Linkage] => with freetype
[T1Lib Support] =>
[GIF Read Support] => 1
[GIF Create Support] => 1
[JPG Support] => 1
[PNG Support] => 1
[WBMP Support] => 1
[XPM Support] =>
[XBM Support] => 1
[JIS-mapped Japanese Font Support] =>
)




This shows GD is enabled.


But, I don't know why it doesn't show the image but a string of weird characters.
If I run the following code, and image is created in the specified local directory below, but only an orange square is created(png file), but with NO STRING attached to it:



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

$string = "hey dude.......";
$im = imagecreate(600,900);
$orange = imagecolorallocate($im, 220, 210, 60);
imagestring($im,5,3,1,$string,$orange);

//saves image to "myimage.png"

imagepng($im,"myimage.png");


Is there something I am missing? It seems I have all the files in place. I put bgd.dll, and php_gd2.dll in the Systems directory in Windows.
I also uncommented the line required on php.ini for extensions, so it seems it is loading that module.




Please help me. All your help is very much appreciated.




Thanks!!




Alberto


ps: I am running PHP version 5.0.4

Make sure you have no characters before the opening "<?php". If you do, those characters will cause the symptoms you're seeing.

Thanks Ken,



I already fixed the weird charcters printing, but still the image doesn't show up. Only the sad square box with the X in the middle.



Do you have any ideas what the problem might be?



Thanks.

Maybe this will work... With two diffrent files.
Put this part of code in makepic.php:
<?php 
header ("Content-type: image/png"); 
$img_handle = ImageCreate (230, 20) or die ("Cannot Create image"); 
$back_color = ImageColorAllocate ($img_handle, 0, 10, 10); 
$txt_color = ImageColorAllocate ($img_handle, 233, 114, 191); 
ImageString ($img_handle, 31, 5, 5, "My first Program with GD", $txt_color); 
ImagePng ($img_handle); 
?>
Then on the page calling the pic do the following:
<img src="makepic.php" border="0" />
Orio.
Think you're smarty?

(Gone until 20 to November)

thanks orio,


I already fixed it, and yes...I tried what you said, but that was not the problem. I was leaving a space at the beggining of the file.:(

Regards,
