And if you hit Apply the python console is pre-filled with a call:



So, possibly, using the same names as in the python example code:

Code:

pdb.file_dds_save(image, drawable, outfile, outfile, 7, 0, 0, 0, 0, 7, 0, True,True,2.24,True,False,.5)

Where the 7 is the documented value for RXGB (DXT5).

The python documentation should be read with a grain of salt because it is auto-generated from the same sources as the script-fu docs and Pythin and Scheme have a different syntax.

• Dashes in variable/constant names should be replaced by underscores
  
• When present, the run-mode first argument should be ignored, it is not used in Python (it is actually optional, and specified differently)
  
• Toggles that are specified as INT32 can be entered as boolean (False: 0, True: 1, and mind the initial capital). This is a bit more readable.
  
• Many calls define constants names for their arguments when necessary, better use them when they exists (alas, not for the DDS plugin, it they had existed you could have used DDS_FORMAT_RXGB_DXT5 and DDS_MIPMAPS_NONE that are a bit less mysterious than 7 and 0)
  
• For long calls, you can also enter the call like this, to put a comment with each argument, only the first line needs to be correctly indented:
  

Code:

pdb.file_dds_save(image, drawable, outfile, outfile,
                    7,      # DDS type
                    0,      # no mipmaps
                    0,      # save layer
                    0,      # Default pixel format
                    0,      # Transparent color is First
                    7,      # Lanczos filtering
                    0,      # Default wrap mode
                    True,   # gamma-correct filtering
                    True,   # Use sRGB
                    2.24,   # Gamma value
                    True,   # Perceptual compression
                    False,  # Preserve alpha
                    .5,     # Alpha (ignored, due to previous)
                    )        

ok thanks I will try that

It is not, since it is specified in the shell command that launches gimp (the './images' string, that you can replace by any directory spec).

Code:

gimp -idf --batch-interpreter python-fu-eval -b "import sys;sys.path=['.']+sys.path;import batch;batch.run('./images')" -b "pdb.gimp_quit(1)"

If you are on Windows, note that for Python backslashes in strings have a special meaning so have to be doubled if they keep their plain character status, but you can uses plain slashes instead, so it's either  'C:\\Path\\to\\some\\directory' or 'C:/Path/to/some/directory'(*)

(*) For completeness tattooed python users can also use the form r'C:\Path\to\some\directory' but they know better

It is not, since it is specified in the shell command that launches gimp (the './images' string, that you can replace by any directory spec).

Code:

gimp -idf --batch-interpreter python-fu-eval -b "import sys;sys.path=['.']+sys.path;import batch;batch.run('./images')" -b "pdb.gimp_quit(1)"

ok thanks I think i get it now, I hope

got a error here is the console

This line isn't meant for the Python console. It is used to invoke Gimp from a command prompt (CMD.EXE, DOS shell, "black screen", etc...)

Running everything in the Python console is possible too. Copy-paste the definition of the run() and process() methods in the Python console, and then call run('/path/to/directory') in that same Python console.

Several ways. But frankly, if you have to ask this... it's a bit as if you asked for instructions to fix your car transmission, and you don't know how to open the hood...

sorry i thought the   python console was the command prompt, so i dont know how to open the hood lol. still new to gimp coming from photoshop

found it nevermind

Now you are in Windows territory...  you have two problems:

1. You appear to be running the "PowerShell" and not the classic (aka "DOS" shell). Maybe the PS is compatible enough, but the command is crafted to navigate the intricacies of the quoting syntax in both the shell and the Python language, so it the shell syntax is bit different this could break things.
   
2. In either shell, when you issue a command (gimp in this case) it searches a gimp.exe in a set of known directories. But these are known to the system because they have been added to the PATH environment variable. An alternative is to specify the full path to the executable (which is fraught with peril since MS had the great idea to use a name with spaces in it, so you have to add more quotes).
   

This is about as far as I can get for you. To go further I'll have to make screenshots, which means installing Windows somewhere... and nope.
