Whitlisting file inputs - radzo73 - 12-22-2019

Hey,
I have a script that takes all the files in a folder, crops them, and exports them. However, it tries to take things in that folder that aren't images (text files, pesky invisible metadata files) and tries to edit them, which throws an error. How do I fix that?

RE: Whitlisting file inputs - Ofnuts - 12-22-2019

Just skip files with a extension which isn't PNG, something like:

Code:

filename,fileext = os.path.splitext(element) # replaces a line of yours

if fileext[1:].upper() != 'PNG':

    continue

You can also more directly get the files you need:

Code:

import glob

files=glob.glob(os.path.join(file_inpath,'*.png')  # elements have their full paths

Unless I'm mistaken the file_mask is always the same, so this will always yield the same result:

Code:

# Add mask to new layer over image

layer_mask = pdb.gimp_file_load_layer(image,file_mask)

pdb.gimp_image_insert_layer(image,layer_mask,None,0)

# Mask layer alpha to selection

pdb.gimp_image_select_item(image,2,pdb.gimp_image_get_active_layer(image))

pdb.gimp_image_remove_layer(image,layer_mask)

# Invert Selection

pdb.gimp_selection_invert(image)

# Crop to selection

dimensions = pdb.gimp_selection_bounds(image)

So you can do it once for all, opening the mask as a separate image, that you discard once you have the values.

Thanks for the ideas!
However when you mentioned

Code:

filename,fileext = os.path.splitext(element) # replaces a line of yours

if fileext[1:].upper() != 'PNG':

   continue

What line would it replace?

nvm, got it working. Again, thanks!
