@Anushlinux you have understood and handled a lot of code flows(in local scripts) to OMRChecker. Great work on your first PR! 🎉
I've finished my review and I think we will need some discussion to make it even more extensible. Let's discuss async in the discord channel once you go through my comments.

Let's keep all these comments as a guide for the contributors to figure out what needs to be done here

let's also include file name here

| for i, page in enumerate(pages): | |
| output_path = os.path.join(output_dir, f"page_{i + 1}.jpg") | |
| page.save(output_path, 'JPEG') | |
| pages = convert_from_path(input_path) | |
| input_path = Path(PurePosixPath(input_path).as_posix()) | |
| file_name = input_path.name | |
| for i, page in enumerate(pages): | |
| output_path = os.path.join(output_dir, f"{file_name}_page_{i + 1}.jpg") | |
| print(f"Saving page: {output_path}") | |
| page.save(output_path, 'JPEG') |

Also convert_image and convert_pdf_to_jpg should come from image_utils instead of bulk_ops_common.py.
I am thinking of keeping this file only for operations that are common across all sorts of bulk scripts (bulk resize, convert, watermark, etc)

I have a feature extension idea here, see if you can implement -
Let's add a support to extract only the first page based on a flag (in that case the image's output_dir shouldn't be created and the single image should be output directly with same filename without the page_ prefix.

snake case

Let's keep pdf handling in a separate script (check other comments)
| extensions = ['png', 'jpg', 'jpeg', 'tiff', 'tif', 'pdf'] | |
| extensions = ['png', 'jpg', 'jpeg', 'tiff', 'tif'] |
| for input_path in filepaths: | ||
| relative_path = os.path.relpath(os.path.dirname(input_path), input_dir) | ||
| output_subdir = os.path.join(output_dir, relative_path) if not in_place else os.path.dirname(input_path) | ||
| os.makedirs(output_subdir, exist_ok=True) | ||

The in_place flag handling can be a common bulk ops utility. I propose we define a function bulk_apply_on_files(func, input_dir, file_paths, in_place)
- The first arg
funccan beconvert_imageorconvert_pdf_to_image - The bulk_apply_on_files applies this passed function with the same arguments
- if in_place is
Trueand the conversion was successful, the input file gets removed (pdf or image) and the output files are added in the same directory - if in_place is
Falseand the conversion was successful, the output files are added in a relative directory output_dir =f"{input_dir}/outputs/" - If the conversion was unsuccessful, no file changes happen
- if in_place is
Let's discuss more about this in the discord group if needed.

Here we can call the function bulk_apply_on_files(convert_image, input_dir, file_paths, in_place) or something similar based on our discussion (check other comments below)

I have updated the conversion code and implemented my function to the convert_image_hook as you required
Pls review the code
(ps: sorry for deleting the previous pr i did it bimistake)
