Poor .jpg image quality in batch swap (with solution)

[Benjamin1973]

After a bit of detective work, I found that swapper.py has the following:

def batch_process()

    . . . 

    if save_path:
        for img in current_images:
            img.save(path)  # Default behavior

But it seems the default quality level for .jpg files is very very low (maybe 60?). If you don't mind hard-coding quality levels, you can try something like:

    for img in current_images:
        ext = os.path.splitext(path)[1].lower()
        if ext in [".jpg", ".jpeg"]:
            img.save(path, format="JPEG", quality=95)  # Higher quality JPEG
        elif ext == ".png":
            img.save(path, format="PNG", compress_level=0)  # Lossless PNG
        else:
            img.save(path)  # Default behavior

Othewise you'll have to modify the batch menu to include a quality setting, which shouldn't be too hard.
