Use Photoshop from command line

Question

Is it possible to use Photoshop.exe from command line for various tasks, such as export PSD files?

(I know it's possible with third party tools such as ImageMagick, but here I'm asking specifically about Photoshop.exe)

Example of what I'm looking for:

Phtoshop.exe myfile.psd --export=myfile.png

Phtoshop.exe myfile.psd --export=myfile.jpg

Phtoshop.exe myfile.psd --export=myfile.jpg --resize=600x600,bicubic

What options are available via command line?

Note: I've tested Photoshop.exe -h, Photoshop.exe --help, Photoshop.exe /?, Photoshop.exe /h, but none of them worked.

(Goal: to be able to automate things for hundreds of images, scripting, etc. not from inside Photoshop, but directly from command line.)

Answer 1

If you are willing to write a script wrapper then sure why not. But using the executable for like this makes little sense for the sheer time it takes to start the program to a state that does abdolutely nothing. So you are better of starting photoshop into the bacground and use it as a server (then its speedy enough)

Answer 2

It seems not possible via command line with Photoshop.exe.

A possible solution is to use Photoshop via a Python script. As an example, this exports any PSD file into a JPG (resized to a width of 1000 pixels):

from win32com.client import Dispatch

infile = "test.psd"
outfile1 = infile[:-4] + "_export.jpg"

app = Dispatch("Photoshop.Application")
app.Open(infile)
app.Preferences.RulerUnits = 1  # pixels
doc = app.Application.ActiveDocument
options = Dispatch('Photoshop.ExportOptionsSaveForWeb')  
options.Format = 6   # JPG  
options.Quality = 80
doc.ResizeImage(1000)
doc.Export(ExportIn=outfile1, ExportAs=2, Options=options)
doc.Close(Saving=2)  # 2 = psDoNotSaveChanges
app.Quit()
