I posted this first looking for info on images and acidfree, but got no responses. I'm really looking for general info on how Drupal uses image toolkits (Imagemagick, GD2, etc). Is it possible to manipulate and edit photos in Drupal? I've searched around and can't find any general info on this, and I don't see any obvious way to do it, but there are references in other posts that seem to imply that its possible.

Can someone give me a little background on this or point me to some useful information on making this work?

Thanks!

Take a look at the image.module which is part of Drupal core, it handles these tasks for other modules which provide a UI without needing to know what toolkit is being used.

Sorry - I'm sure I'm missing something obvious here. I have the image.module installed and activated (I'm using the latest 4.7 install with Acidfree 4.7). I've looked in settings and gone to edit both image.module nodes and acidfree nodes, and I don't see anything about editing or manipulating the photo. Can you point me to where I should be looking?

thanks,
Nick

Take a look at the modules download section to find a module which does what you want, e.g. here:

http://drupal.org/project/Modules/category/67

and here:

http://drupal.org/project/Modules/category/58

These modules make use of the image.module to do the actual image manipulation, they act as a front end for it. Each one is designed for particular types of image handling, everything from a gallery to inserting images in nodes.

Robert - thanks for your quick replies. I think I may not be being clear (or maybe what I'm asking for doesn't exist). i'm using Acidfree to allow users to upload images and display galleries. I thought (and maybe I'm wrong) that there was a way to do things like crop and make other adjustments once those images were uploaded. I have the latest versions of image.module and acidfree.module for 4.7RC4 working on my site. Is this something that works in Drupal, or am I mistaken? Is there some sort of setting or software install that is needed on my server that would keep this from working?

So - I finally figured out that I needed to have the image.imagemagick.inc file from acidfree in the includes menu and that it needed a different path for convert, so I can now select ImageMagick as my image processing toolkit in admin>>settings, and now image.module is creating thumbnails, but there are no options for manipulating photos. Any suggestions on other things to check?

Unless something has changed since I last looked at this stuff (quite possible), the image processing toolkits aren't for the users benefit - they are for the modules internal use. eg the module uses the toolkits to automatically create thumbnails etc.

They aren't intended to be used for an online version of Photoshop or anything.

Exactly what did you do to get ImageMagick working in Drupal 4.7? I've tried everything I can think of to get it to generate thumbnails, but I'm still getting the message, "Unable to generate thumbnail image."

There's ImageMagick module that's in some state of arrested development.

Anyone interested in getting a bounty together to get some of the most basic image manipulation functionality available to the user interface?

No matter how clunky the UI for rotating an image, it's better than having to delete and re-upload.

hey guys, I would be very interested in this. Has anyone developed something along these lines?

I need to have very simple and basic operations for online users to be able to manipulate their uploaded images, such as rotate, scale, move and add text.

Anything??
