Integrating GD Library with Coppermine?

[Frink]

Is it possible to integrate the GD Library with Coppermine?

Here is the link to their site if it helps http://www.libgd.org/Main_Page. 

If it is possible to integrate the GD Library with Coppermine I would greatly appreciate any help.

Coppermine already using GD library to manipulate pictures
I don't know which type of integration you are looking for

[Frink]

Well I want to be able to update the GD Library with the up-to-date version and I don't know how to use GD's commands.   Here are the commands/codes I want to use http://search.cpan.org/~burak/GD-Thumbnail-1.10/lib/GD/Thumbnail.pm#create

[Joachim Müller]

Support for GD needs to be compiled into PHP - that's not something a web-driven app like coppermine can do. If you don't have GD available on your server, you'll need to talk to your webhost. As Sami suggested, Coppermine already uses GD, so your question doesn't apply. Marking this thread as "invalid" and moving it accordingly, as your question is not related to bridging. Coppermine is using the GD library to create the thumbnails and intermediate-sized images.
Please read the FAQ.

[Frink]

I should clarify this question.  I want to use these commands with Coppermine.  http://search.cpan.org/~burak/GD-Thumbnail-1.10/lib/GD/Thumbnail.pm.

use GD::Thumbnail;
   my $thumb = GD::Thumbnail->new;
   my $raw   = $thumb->create('test.jpg', 80, 2);
   my $mime  = $thumb->mime;
   warn sprintf "Dimension: %sx%s\n", $thumb->width, $thumb->height;
   open    IMG, ">thumb.$mime" or die "Error: $!";
   binmode IMG;
   print   IMG $raw;
   close   IMG;

my $raw = $thumb->create($image    , $max, $info);
   my $raw = $thumb->create('test.jpg',   80, 1    );

Is there a file I can put these commands in, such as the index.php, so I can use GD's thumbnail output?

[Joachim Müller]

Look: as suggested, Coppermine already creates the thumbnails for you. There's no need to add code to dynamically create thumbnails, as this would mean a huge waste of resources to re-create the thumbnail whenever it is needed. If you must have this code, then you'll have to figure this out on your own where exactly to apply it - I'm not going to waste hours to integrate your suggested code into the coppermine core code. Coppermine already has the needed functions as well to create a thumbnail - if you need dynamically-created thumbnails, you can use that function (although it absolutely doesn't make sense at all). Why don't you go ahead and explain why you so badly insist on having that particular piece of code reside in Coppermine. Maybe someone will come up with the needed code changes if you can explain why you need them.

Where is this function located? 

[Joachim Müller]

Search the core code - as suggested, I'm not going to look into this for you, as it is silly in the first place. You need it -> you code it. Won't answer any more questions, as you failed to do as suggested:

I'm not going to waste my time for to explain how coppermine works. If you're a skilled coder, you can find out easily. If you're not a coder, you won't be able to accomplish the hack you're after.

Well I want to be able to adjust the different ways thumbnails are exported.  (Such as altering the ways generating thumbnails are made) 


I want to overlay image info, such as the size of the raw image, on the thumbnail.

I don't understand. Please re-phrase.

This is called "watermarking" and has been covered in many threads/mods already.

The code you posted is perl; you can't use perl in Coppermine as it is a php app. If you want to modify the image creation code look at resize_image() in include/picmgmt.inc.php

Thanks Nibbler. 

I found a script which has what I want that uses GD.  But I have no clue where to put it.

Here is what it looks like...

<?php

Here is where I got the script from http://www.phpgd.com/scripts.php?script=38.

If anyone one the board can help me, it will be greatly appreciated.

As suggested various times on this thread, your request is invalid in the first place, since coppermine already comes with GD support, so there's no use in re-requesting it. Your customization requests are beyond what you can expect from regular free support, so you're on your own with this: code it by yourself or hire someone to code it for you. Please do not try to draw attention to your request that has been labelled "invalid" for good reasons by bumping it constantly to the top with code snippets taken from some place. Coming up with working code doesn't just mean copying bits of code from all over the internet and just pasting it into the corresponding sections in Coppermine. What you're up to requires in-depth understanding of coppermine, good coding skills and a lot of time to come up with the code and test it.
Additionally, you haven't done as suggested

I don't understand. Please re-phrase.

, so I'm reluctant to see this discussion continue.
