Hello,

Is it possible to combine few tiff's from a folder (mostly 8 but sometimes less) as a one new tiff containing all those tiff's from a folder as layers (names of the layers can be the names of the tiffs)?

Would be perfect is this could be done by a droplet (i put desired folder onto a droplet and as a result i get a signle tiff with multiple layers)

Actions and scripting

Hi @Michal278606593tfz are you on a Mac? If so, you could use Automator to run droplets on designated folders.

Hi, I'm on PC. I don't have access to Mac.

And I described wrong what I need.

I need one tiff with as many channels as there are 1-bit tiff files in the folder.

Converting those 1-bit tiff's into a channels takes so much time that it would help me so much if it could be automated.

I took the liberty of adapting @Stephen Marsh ’s code, see if this helps.

I don’t think a droplet for Folders is plausible for Photoshop but other than that: How experienced are you with JavaScript and Photoshop’s DOM?

Maybe JJMack’s PhotoCollageToolkit can prove useful to you:

Well I can't write a script but at least I know how to use them 😉

I asked about the droplet because the script won't speed up/automate too much, but of course it will be helpful.
I was hoping that what I need is not too complicated and I can automate it.

In a nutshell, the idea is to merge several tiff files (1-bit/bitmap) into one with layers (gray/cmyk whatever)
