我很抱歉，如果我要去我引起一些混淆的问题，因为它涉及到的东西，也许是不可能的，但我d喜欢使用winforms创建一个允许用户加载图像的表单，从组合框中选择一些证书级别，然后将其相关的图章放在所述图像上...的WinForms - 将图像在另一个图像（邮票等），并将其保存
我遇到的问题是：加载工作得很好，从组合框中选择（因为我甚至知道如何从特定位置获得特定图像（让我们称之为'邮票'），并将它们放入一个picturebox中），我甚至可以保存第一个加载图片（我们称之为'pic1'作为参考）......但我不知道如何编程将'邮票'放置在'pic1'上......地狱我可以几乎没有编码所需的线，我已经做了，格式除外，并不会没有帮助从'stackoverflow'...
真相被告知，我刚刚完成了一些糟糕的200小时在C＃编码（和他们没有在网上了解到，它实际上是一个过程-_-...的一部分）
任何想法，帮助，建议甚至是“回到你开始之前在做什么弄乱编程“，请吗？
谢谢你提前。我会离开这里，我已经有...
PS：我没有太多的经验，无论是面向对象，这就是为什么下面的代码不会像什么真正优化...：■
顺便说一句，在消息框内的下面的字符串是葡萄牙语，因为用户是我的父亲，并且对他来说，在葡萄牙，使用葡萄牙语工作的形式会更容易...
哦，如果你知道任何其他语言，我应该也许这样做，请给作为反馈...非常感谢:)

再次感谢你对那些谁帮助:)
TL; DR ......您是否在寻找水印？ SO（英文和西班牙文）有很多关于渲染位图或保存图像的问题 - 所以不太清楚你卡在哪里。 –
我们对此深感抱歉...问题是我真的不知道很多关于编程和无法理解阉我需要什么适合我水印类别或不...也许它只是让我太小白和没有经验的，或者说，我没有尝试过足够...对不起，让你失去了你的时间来回答...谢谢反正 –
