Title: GD Graphics Library with PHP
Post by: Tom Peck on April 05, 2001, 05:04:01 AM

Hello

PHP has been configured by default with the GD library like so: '--with-gd=shared'

How then do we use this library?  I've tried a few different methods, including the example from PHP.net, which is this:

header ("Content-type: image/png");
$im = @ImageCreate (50, 100)
    or die ("Cannot Initialize new GD image stream");
$background_color = ImageColorAllocate ($im, 255, 255, 255);
$text_color = ImageColorAllocate ($im, 233, 14, 91);
ImageString ($im, 1, 5, 5,  "A Simple Text String", $text_color);
ImagePng ($im);
?>

But they don't appear to work..  Has anyone successfully managed to use the GD library?

Cheers

Tom

First, look at a phpinfo(); page.  If it doesn't include a heading for gd, you don't have GD support.  I believe e-smith is using stock RedHat 7 PHP RPMs, so you'd need to locate a php-gd RPM from RedHat 7.  Alternatively, upgrade your PHP RPMs to 4.0.4pl1 from rpms.arvin.dk.

Thanks for the Info Dan - that site is damn fine!

Quick question:  Should I remove the existing PHP RPM before installing the new RPMs?  Is this going to cause problems with e-smith if I do this?

Cheers

Tom

You shouldn't need to remove the existing PHP RPM--my recollection is that I just downloaded the new ones and did rpm -Uvh on them.

Here is what i did, and it seems to work very well :

I tried to upgrade PHP with RH7.0-upgrade RPMS but i had dependances problems with arvin's ones.
So, I downloaded all RPMs from http://rpms.arvin.dk/php/install-ready/i586/ (my e-smith box processor is an AMD K5).

rpm -Uvh --nodeps php-4.0.4pl1-10.arvin.i586.rpm
rpm -Uvh mod_php-4.0.4pl1-10.arvin.i586.rpm
rpm -Uvh php-imap-4.0.4pl1-10.arvin.i586.rpm
rpm -Uvh php-mysql-4.0.4pl1-10.arvin.i586.rpm
rpm -Uvh php-ldap-4.0.4pl1-10.arvin.i586.rpm
rpm -Uvh php-gd-4.0.4pl1-10.arvin.i586.rpm
/etc/rc.d/init.d/httpd-e-smith restart
/etc/rc.d/init.d/httpd-admin restart
/etc/rc.d/init.d/httpd restart

Now, imagecreate() and other graphic functions work great and i haven't yet noticed any problem with IMP or e-smith-manager.

Regards.

thanks for the really good url, but do you have an idea where I can find rpms for the i386-architecture? (I have an 486-DX-PC)

Thanks

sorry, just found some modules, also by alvin, at rpmfind.net, for i386.

some other rpms (like expat-1.95...) needed but if they are installed it works like hell ;-).

Well, i have found too late the php-gd-4.0.3pl1-4.i386.rpm on
ftp.e-smith.org/e-smith/contrib/DanBrown/RPMS/i386

Of course, i haven't tested it. But i guess it should work fine

Regards.
