Hi,

Does anyone know of a good way to do server-side image processing, and take advantage of Photoshop’s filters (e.g. drop shadow, inner glow, etc.). Basically we need the image quality of Photoshop, but all the images are processed in a multi-threaded non-GUI service. I know Photoshop does expose an automation interface, but that would require PS to be installed on the server, and moreover it is not suitable for high-performance use (due to the fact that it needs a GUI and is a single-use COM server).

Any suggestions would be appreciated.

Thanks.

Yes. It is not too hard to noodle out. Have a _licensed_ version of PS on a machine (call it a server if you want). Have a simple process watching a drop folder. When the folder changes, pick up the user id from the drop-process (hopefully FTP), thene= invoke PS via a droplet that does what you want it to do against the folder. Set the rights of the user to the folder. Of course there is more to it, and there is a _lot_ one can do in this regard, but I don’t think we should be doing the job for one with such ambitions. Work out the rest on your own.

Do you mean watch a folder for Photoshop files (i.e. PSDs) dropped into it? Actually, I don’t really need to work with Photoshop files so much as use Photoshop’s filters on some in-memory raster image. Also, the user accessing the service is not particularly important, so I’m not clear as to why it would be needed, as noted below. Besides, the service may have to deal with many users so it would not scale if PS were invoked for every user. I was trying to avoid having to invoke PS and if possible, work solely in a service (non-GUI) context.

So briefly, you want Adobe’s filters, but not the Photoshop GUI. You might want to pursue a command-line approach which does things similar to Photoshop without their proprietary filters. There are such things, and I do that under (of all things) VMS but lately with Windows. Since this is an Adobe Photoshop forum, I won’t get into it any further.
