Pixel を使用して、大きな画像と小さな画像の間で検索を行っていました。私はそれを正常に動作させましたが、lockbits バージョンでやりたいことを実行するのに問題があります。
まず、大きな画像をループして、その中の小さな画像の最初のピクセルを見つけたいと思います。次に、数学の方程式を実行する最初のピクセルを見つけて、それが何パーセントの精度を達成したかを教えてくれます。そうすることで、大きな画像内の小さな画像の最初のピクセル（左上）にある画面上のその場所にマウスを移動する基準を満たしている場合。これは成功率が高く、GetPixel 形式に比べて非常に高速です。
問題 小さな画像の開始ピクセルがどこにあるかの大きな画像上の位置を取得できず、マウスをその位置に移動できません。以下はコードです：

マウスを画面上で移動させる方法を理解できれば、それを理解できたでしょう。残念ながら、私はこれに数日間取り組んできましたが、成功しませんでした。お役に立てれば幸いです。前もって感謝します。
