GD Image Lib Not Working

[JustinK101]

Hello, I am trying to use the GD Library to draw an image with text in it. Here is the code I am using:

 

$img_handle = ImageCreate (230, 20) or die ("Fatal Error: Cannot create image in PHP library GD."); 
$back_color = ImageColorAllocate ($img_handle, 0, 10, 10); 
$txt_color = ImageColorAllocate ($img_handle, 233, 114, 191); 
ImageString ($img_handle, 31, 5, 5,  $row_customer['approx_number_of_units'], $txt_color);

 

This is simply outputting:

 

‰PNG IHDRæ£þÓêPLTE ér¿`ŽL+IDATxœc`ià@IÆðÈ2œÏäÃ<#‹ßUø}ô!Ÿ^ò%õ ÆƳÚýIEND®B`‚

 

Thanks for the help.

Ok the trick to place GD images in your page with other html and php content is to put the GD php code in a seperate file. For example:

 

FileName: gd_create_text_image.php

<?php
header("Content-type: image/png");
$string = $_GET['text'];
$img_handle = ImageCreate(100, 20) or die ("Fatal Error: Cannot create image in PHP library GD."); 
$back_color = ImageColorAllocate ($img_handle, 255, 255, 255); 
$txt_color = ImageColorAllocate ($img_handle, 0, 0, 0); 
ImageString($img_handle, 5, 5, 5,  $string, $txt_color);
imagepng($img_handle);
imagedestroy($img_handle);
?> 

 

Then in your page simply use a standard HTML img tag as follow:

 

echo '<img src="gd_create_text_image.php?text=' . $row['approx_number_of_units'] . '">';
