我很抱歉，如果我要去我引起一些混淆的問題，因爲它涉及到的東西，也許是不可能的，但我d喜歡使用winforms創建一個允許用戶加載圖像的表單，從組合框中選擇一些證書級別，然後將其相關的圖章放在所述圖像上...的WinForms - 將圖像在另一個圖像（郵票等），並將其保存
我遇到的問題是：加載工作得很好，從組合框中選擇（因爲我甚至知道如何從特定位置獲得特定圖像（讓我們稱之爲'郵票'），並將它們放入一個picturebox中），我甚至可以保存第一個加載圖片（我們稱之爲'pic1'作爲參考）......但我不知道如何編程將'郵票'放置在'pic1'上......地獄我可以幾乎沒有編碼所需的線，我已經做了，格式除外，並不會沒有幫助從'stackoverflow'...
真相被告知，我剛剛完成了一些糟糕的200小時在C＃編碼（和他們沒有在網上了解到，它實際上是一個過程-_-...的一部分）
任何想法，幫助，建議甚至是「回到你開始之前在做什麼弄亂編程「，請嗎？
謝謝你提前。我會離開這裏，我已經有...
PS：我沒有太多的經驗，無論是面向對象，這就是爲什麼下面的代碼不會像什麼真正優化...：■
順便說一句，在消息框內的下面的字符串是葡萄牙語，因爲用戶是我的父親，並且對他來說，在葡萄牙，使用葡萄牙語工作的形式會更容易...
哦，如果你知道任何其他語言，我應該也許這樣做，請給作爲反饋...非常感謝:)

再次感謝你對那些誰幫助:)
TL; DR ......您是否在尋找水印？ SO（英文和西班牙文）有很多關於渲染位圖或保存圖像的問題 - 所以不太清楚你卡在哪裏。 –
我們對此深感抱歉...問題是我真的不知道很多關於編程和無法理解閹我需要什麼適合我水印類別或不...也許它只是讓我太小白和沒有經驗的，或者說，我沒有嘗試過足夠...對不起，讓你失去了你的時間來回答...謝謝反正 –
