Description
Hi
Ive been trying to enable the CAPTCHA images.
I get this message:
"Images cannot be generated, because your PHP installation's GD library has no JPEG support."
My PHP configure:
'./configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-mysql' '--enable-soap' '--with-openssl' '--with-gd' '--with-jpeg-dir=/usr' '--with-ttf' '--with-freetype' '--enable-gd-native-ttf'
My PHP version is 5.2.3
Working on Linux.
Drupal 5.5
downloaded gdlib, jpeglib is available at /usr.
Other ideas?
I've got this thread going on too: http://drupal.org/node/205298#comment-675529 but still no luck.
Thank in advance,
Rocky

could you execute the following php on your server, for example by creating a new page with the "PHP code" input format:
<?phpif (function_exists('imagegd2')) {
var_export(gd_info());
}
$fs = array('imagejpeg', 'imagecreatetruecolor', 'imagedestroy',
'imagecolorallocate', 'imagefilledrectangle', 'imagecolorat', 'imagesetpixel',
'imageline', 'imagefontwidth', 'imagettfbbox', 'imagestring', 'imagettftext',
);
foreach($fs as $f) {
print "$f: ". var_export(function_exists($f), TRUE) .'<br />';
}
?>
and post the result?

sure - here's the result:
what now?

You have no jpeg support. I'm not very familiar with compiling PHP, so I can't help you with this.
But you seem to have PNG support.
If you are not afraid of hacking, you could change image_captcha to work with PNG instead of JPEG.
at first sight, the only changes in "image_captcha.module" you should do are:
replace "imagejpeg" with "imagepng" (globally in the source code)
and replace 'drupal_set_header("Content-type: image/jpeg");' with 'drupal_set_header("Content-type: image/png");' (around line 400)
try this and report your findings (and post a patch)
I have no time right now to do it myself

Good job!
I've hacked it to use png and it works now.
Thanks!
what do you mean by "post a patch"?
and where can i find fonts to use with the captcha, cince it keeps warning me about the default font?
thank you anyway

If you're not familiar with this, it will probably be easier to do it myself than explaining this, so nevermind ;)
If you're still interested: http://drupal.org/patch
Also note that you now have a custom version of the image CAPTCHA module, so any future upgrade of the module will overwrite your changes.
There are thousands of font sites out there.
I use http://www.dafont.com often

if you follow the hints on your forum thread you might even get jpeg working. It's difficult to keep two seperate pleas for help under control
