Gimp Python script file load question

[TimorousMe]

Hi Kevin. Yes that is me. My latest plugin is shown below. Everything works in the GIMP UI, but when I add my call for pdb.gimp_xcf_load(0, infileA, infileA) and introduce infileA into the definition and parameters, it fails. 

I think there may be a problem because the image object isn't explicitly linked to my XCF or JPG. It would be great to avoid a file wrapper for opening the XCF, but if I need to I understand. 

Below is my command line calls (two options I tried) and my plugin. These are the errors I get when I use these command line calls:

First command line call: "Error: eval: unbound variable: open_add_flatten_export"

Second command line call:

GIMP-Error: Failed to save data:

You have a writable data folder configured (/Users/TBradley/Library/Application Support/GIMP/2.10/gradients), but this folder does not exist. Please create the folder or fix your configuration in the Preferences dialog's 'Folders' section.

EEEEeEeek! 9 GeglBuffers leaked

Quote:First command line call:

gimp -i -b '(open_add_flatten_export "/Users/TimB/Desktop/xcf_template.xcf" "/Users/TimB/Desktop/jpg_to_add.jpg" "2060" "410" "/Users/TimB/Desktop")' -b '(gimp-quit 0)'


Second command line call: 

gimp -i --batch-interpreter python-fu-eval -b pdb.python_fu_open_add_flatten_export "/Users/TimB/Desktop/xcf_template.xcf" "/Users/TimB/Desktop/jpg_to_add.jpg" "2060" "410" "/Users/TimB/desktop" -b 'pdb.gimp_quit(0)'

Here's my plugin:

Code:

#!/usr/bin/env python

from gimpfu import *

def open_add_flatten_export(image, layer, infileA, infileB, x_offset, y_offset, outputFolder):
 
   # Open XCF template
   pdb.gimp_xcf_load(0, infileA, infileA)

   try:
       # Open file.
       fileImage = None

       if(infileB.lower().endswith(('.jpeg', '.jpg'))):
           fileImage = pdb.file_jpeg_load(infileB, infileB)

           # Create new layer.
           newLayer = gimp.Layer(image, "New Layer Name", layer.width, layer.height, layer.type, layer.opacity, layer.mode)
           # the +1 adds it behind the top layer
           image.add_layer(newLayer, +1)

           # Put image into the new layer.
           fileLayer = fileImage.layers[0]
           pdb.gimp_edit_copy(fileLayer)
           floating = pdb.gimp_edit_paste(newLayer, True)

           # Update the new layer.
           newLayer.flush()
           newLayer.merge_shadow(True)
           newLayer.update(0, 0, newLayer.width, newLayer.height)

           # Flatten + offset floating layer, then flatten image
           pdb.gimp_floating_sel_to_layer(floating)
           pdb.gimp_layer_set_offsets(floating, x_offset, y_offset)
           pdb.gimp_image_flatten(image)

           # Export JPG of flattened image
           layer = pdb.gimp_image_get_active_layer(image)
           pdb.file_jpeg_save(image, layer, outputFolder + "/" + "export.jpg", "raw_filename", 0.9, 0, 0, 0, "Creating with GIMP", 0, 0, 0, 0)

       else:
           gimp.message("The image could not be opened since it is not an image file.")

   except Exception as err:
       gimp.message("Unexpected error: " + str(err))
