Combine hundreds of images into one using PS layers modes

"Jean-Marc Molina" wrote in message

I’m looking for a tool or PS plugin to combine hundreds of images into one using PS layers modes : multiply, burn, difference… A plugin would read

a

whole folder like you can do it using Batch processing, read all the files and merge/combine them together using the multiply mode for example. The goal is to get the trail of the moving objects of my images.
I’m not sure I can use Batch mode or scripts/actions to automate that process, so I thought about a plugin or external tool.

If you decide you could use a VBScript, I should be able to write a simple one in about 10 minutes, barring unforeseen bugs in the scripting plug-in. Options regarding blending mode, opacity, etc. would take a little longer.

Hi Warren,

After I read your post I checked for Photoshop CS new features and it appears it now supports Scripting.
I’m glad it does ! I’m only a PS6 owner and as a developer I could really use powerful scripting features instead of these too "designers" Actions/Styles things.

As I can’t try PS CS (no trial ?) I’m looking for any info about CS Scripting. Does it replace the good old SDK ?

If you decide you could use a VBScript, I should be able to write a simple

one in about 10 minutes

Reading the PS CS overview I found out that we can now use "droplets" to batch some stuff but I have no idea they talk about. I know how to use the batch features from PS6 though.

barring unforeseen bugs in the scripting plug-in.

So you use PS7 ? It seems PS7 is scriptable using a plugin you can download. Am I right ? Now it seems the Scripting plugin is embedded into PS CS. Is it that buggy ?

Options regarding blending mode, opacity, etc. would take a little longer.

Quickly checking the JavaScript scripting reference guides (I’m more into JS that VB) it seems we have access to a lot of features !
We can getFiles from an inputFolder, open a Document, duplicate an ArtLayer…

So as you said I think my plugin is quickly scriptable, however It means I have to upgrade to PS7 or PS CS… I don’t think learning PS Scripting is that hard as the scripting guides are pretty well written, there are so very interesting examples to learn from.

Last but not least, do you know of any good "PS Scripters" community ? Tutorials ? Articles ? Anything 🙂

Thanks for all your help,
JM

(Speaking of V7, and assuming V8 is similar) – Droplets are like ‘compiled’ (binary image) Actions passed to Photoshop, rather like Batch but Photoshop need not be open when they are invoked. When you drag a file onto a Droplet, it passes the picture’s file path/name along with the actions to perform. It’s like batch processing with some ‘gotchas’ concerning file placement (at least in V7) which are not really daunting. (In WindoZe you can invoke a droplet from CMD mode as
dev:path/’droplet’.exe plus the full path of the file(s) name to process. This is good for scheduling jobs.)

See my earlier post to find the Droplets provided in the standard installation (V6 as well as V7. Dunno about CS!)

No, scripting is much slower than plug-ins using the SDK. But you have to pay for the SDK now (at least for PS7).

download.

Am I right ?

Yes. I use the scripting plug-in regularly in Photoshop 7.

In PS7, it is very, very buggy. Adobe’s Javascript implementation really sucks.
VBScript is not quite so bad. I don’t have Photoshop CS yet, but it allegedly
has improved scripting support.

If you are already familiar with scripting, Photoshop scripting is not too hard. But the documentation for scripting in PS7 contains many errors, and whoever wrote the doc knows very little about Windows.

Look at the forums at the Adobe web site. There’s one about scripting. Sometimes you can pick up some extremely useful information there, but many questions go unanswered.

Thks can be done with an action except for the merging part. Hundreds of files might make the action stall though.

Here’s what you do. Make a master document big enough (width and height) to put the files into. Don’t move it or the action will likely break.

Record action on an open file: Alt-Ctrl-click to turn Background into a layer. Set the Blending Mode to Multiply, Duplicate Layer with the Destination set as Master File. Close. End recording.

Put the files in a folder (but NOT the master doc) and Batch run it on that folder.

Should work with some experimenting. I hope your system can handle it.

Hard to believe as SDK should be free to attract developers.

VBScript is not quite so bad.

Yes but you need VB.NET 2003 !
JavaScript development both works under Windows and Mac.

Thanks I will check out the forum if needed.

Reading the scripting guides I couldn’t find info about scripting the swatches, it seems we can’t script everything. Probably because Adobe wants to avoid us from improving their product. The swatches could really use a plugin, that was my first attempt when developing a plugin for PS6 using the SDK.

US$195, last time I looked.

I have neither VB nor .NET. All you need is a text editor (notepad will work) and WSH (Windows Scripting Host).
Recent versions of Windows come with WSH, but if you don’t have it, you can download it from Microsoft for free.

Yes, and I think Javascript is a much nicer language than VBScript. The trouble is that Adobe has screwed up some very important features in Javascript, such as the ability to get user input and to re-use code.

There is a thing called the Scripting Listener that allows you to script lots of things that are not explicitly supported by the scripting plug-in or have bugs in the scripting
interface. I don’t know whether it will work with swatches, but it might.
