全シートの背景色または背景イメージを設定するには、backColorまたはbackgroundImageを使用します。背景色と背景イメージの両方を設定した場合は、背景イメージが表示されます。
または、ワークブックのbackgroundImageオプションを使用して、ワークシートの背景画像を設定することもできます。背景画像を設定すると、設定した背景色が上書きされ、背景色を有効にするには背景画像を削除する必要があることに注意してください。
ワークブックのbackgroundImageLayoutオプションを設定することにより、4つのレイアウトのいずれかを選択して、画像の表示方法を変更できます。4つのオプションは次のとおりです：
stretch：領域のサイズが変更された場合でも、背景画像がその領域を塗りつぶします。
center： 背景画像が領域の中央に表示されます。
zoom： 元のアスペクト比を維持したまま、背景画像がその領域に表示されます。
none： 背景画像は、元のサイズで領域の左上隅に表示されます。
