GIMP: A code to edit a whole folder of images

Question

[GIMP 2.8.16]

EDITED: See below.

Hi,

I am new to python, and I need to ask the community to please help me find where is this code failing. I am having trouble. This is version 1.0, following this answer:

import glob
source_folder = "/home/pecesaquadros/Desktop/T/"
dest_folder = "/home/pecesaquadros/Desktop/T2/"

def auto(source_folder, dest_folder):
    for filename in glob(source_folder  + "/*.JPG"):
        img = pdb.gimp_file_load(source_folder + filename, source_folder + filename)
        pdb.gimp_image_rotate(img,0)
        pdb.gimp_image_convert_grayscale(img)
        drawable = pdb.gimp_image_get_active_drawable(img)
        pdb.gimp_brightness_contrast(drawable, 28,100)
        disp = pdb.gimp_display_new(img)
        yield img
        pdb.gimp_image_merge_visible_layers(img, CLIP_TO_IMAGE)
        pdb.gimp_file_save(img, img.layers[0], dest_folder + filename, dest_folder + filename)
        pdb.gimp_display_delete(disp)
        pdb.gimp_image_delete(img)  # drops the image from gimp memory

seq = auto(source_folder, dest_folder)
next(seq)

with output, in GIMP 2.8.16 Python Console:

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "<input>", line 2, in auto
TypeError: 'module' object is not callable

Many thanks. I am sure this question will help many. I might make a plugin out of it, with interesting parameters, available for everybody; it will be named "Photocopy" :)

...next I am creating a loop to create a TeX code that will compile all images to a pdf...

Thanks again,

Al

EDIT

New code:

import glob
source_folder = "/home/pecesaquadros/Desktop/T/"
dest_folder = "/home/pecesaquadros/Desktop/T2/"

def auto(source_folder, dest_folder):
    for filename in glob.glob(source_folder  + "/*.JPG"): #blabla.JPG
        img = pdb.gimp_file_load(filename,filename)
        pdb.gimp_image_rotate(img,0)              #Editing starts
        pdb.gimp_image_convert_grayscale(img)
        pdb.gimp_image_select_rectangle(img, 2, 0, 0, 1839, 600)
        drawable = pdb.gimp_image_get_active_drawable(img)
        pdb.gimp_brightness_contrast(drawable, 60,127)
        pdb.gimp_image_select_rectangle(img, 2, 0, 600, 1839, 900)
        drawable = pdb.gimp_image_get_active_drawable(img)
        pdb.gimp_brightness_contrast(drawable, 32,127)
        pdb.gimp_image_select_rectangle(img, 2, 0, 1500, 1839, 900)
        drawable = pdb.gimp_image_get_active_drawable(img)
        pdb.gimp_brightness_contrast(drawable, 14,127)
        pdb.gimp_image_select_rectangle(img, 2, 0, 2400, 1839, 900)
        drawable = pdb.gimp_image_get_active_drawable(img)
        pdb.gimp_brightness_contrast(drawable, 0,127)
        disp = pdb.gimp_display_new(img)      #Editing ends
        yield img               #Image is displayed for me to manipulate
        pdb.gimp_image_merge_visible_layers(img, CLIP_TO_IMAGE)
        pdb.gimp_file_save(img, img.layers[0],filename,dest_folder + filename)
        pdb.gimp_display_delete(disp)
        pdb.gimp_image_delete(img)

seq = auto(source_folder, dest_folder)
next(seq) #This, and enter, to go to the next file

Results in:

1. Files are overwritten, not saved in the new folder
2. Sometimes, and only sometimes, one of these two errors appear:

A

B

0_0

PS: yield is in my plans.

Answer 1

glob is module that contains a glob function, so that shouldn't be glob(source_folder + "/*.JPG") but glob.glob(source_folder + "/*.JPG")

Also, if you give a path as part of the pattern to glob.glob(), the output will contain the full path to the files. Since you are re-adding the directory name to it, it appears twice in the name you give to gimp_file_load(). So try something like:

for filename in glob.glob(source_folder  + "/*.JPG"):
    img = pdb.gimp_file_load(filename,filename)
