from PIL import Image
class ImageProcessor:
    @staticmethod
    def resize(input_path, output_path, width=None, height=None):
        img = Image.open(input_path)
        if width and height:
            img = img.resize((width, height), Image.LANCZOS)
        elif width:
            r = width / img.width
            img = img.resize((width, int(img.height * r)), Image.LANCZOS)
        elif height:
            r = height / img.height
            img = img.resize((int(img.width * r), height), Image.LANCZOS)
        img.save(output_path)
    @staticmethod
    def batch_resize(input_dir, output_dir, width):
        import os; os.makedirs(output_dir, exist_ok=True)
        for f in os.listdir(input_dir):
            if f.lower().endswith(('.png', '.jpg', '.jpeg')):
                ImageProcessor.resize(
                    os.path.join(input_dir, f),
                    os.path.join(output_dir, f),
                    width=width
                )
