[RESOLVED] Creating images using php

xbuilder

Hi,

I was learning the image creation functions and copied the following code segment from PHP online manual at
http://us3.php.net/manual/en/function.imagecreate.php

I put the code in picture1.php and loaded it using firefox browser, I only see "http://localhost/picture1.php" in the bowser, rather than an image.

There must be something basic that I am missing???

<?php
header("Content-type: image/png");
$im = @imagecreate(110, 20)
    or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 0, 0);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5,  "A Simple Text String", $text_color);
imagepng($im);
imagedestroy($im);
?>

Is display_errors set to On and error_reporting set to E_ALL? Have you tried commenting out the header() call and seeing if there are any errors outputted?

xbuilder

(1) Yes in file /etc/php5/apache2/php.ini, I have the following two lines
display_errors = on
error_reporting = E_ALL

(2) When i commented out the header(...) line and refresh the page, this time, the page displayed is blank

(3) I verified that errors are displayed in the browser, such as I changed
@imagecreate(110, 20)
to
imagecreate(110, 20)
and the error displayed was:
Fatal error: Call to undefined function imagecreate() in /srv/www/htdocs/picture1.php on line 3

Are the image functions not built into the core php or I need some module for it?

Thanks

Indeed they are not - they are a part of the [man]GD[/man] library which is a separate extension to PHP (php_gd).

omg!

Thanks for pointing that out. I installed the php5-gd package and now it runs like a charm!
