は、それが「なしタイプ」オブジェクトは「保存」何の属性を持っていないことを言って表示されます

Question

コーダを実行すると、私は次のエラーメッセージを取得する場合：

“None Type” object has no attribute 'save' 

次のようにスクリプトは次のとおりです。

#Image.blend(image1, image2, alpha) 

from PIL import Image

      new_image_filename = os.path.join(new_directory, filename + str(number)+ '.png') 
      new_image.save(new_image_filename) 
      number+=1 

エラーは、新しいimgが作成された場所に由来します。これは、コードが機能しなくなり、エラーを返すようになったときです。何らかの理由で、新しいimgを値として取っておらず、保存しませんが、私がその部分を取り出して新しいイメージを保存するように頼むとエラーはありません。

問題は、new_imageの画像のontopを貼り付けるときにあります。

Answer 1

make_poster(pict_imgs[x], word_imgs[y]) 

がNoneを返すことが表示されます。 new_imageをNoneに設定します。このような質問を提出するときは、
