使位图成为hDC的内容 [英] make a bitmap the content of a hDC

问题描述

Image imgx = Bitmap.FromFile("test.bmp");
Bitmap bmpx = new Bitmap(imgx);

IntPtr hDC = PlatformInvokeUSER32.GetDC(/* GET DC FROM THE bmpx bitmap */);
PlatformInvokeGDI32.SelectObject(hDC, new IntPtr x(bmpx));

谢谢.如上所述，我希望将文件中的bmp(bmpx)转换为dc(hDC)，以便可以将其与bitblt()配合使用来进行裁剪.

关于如何去做的任何想法?谷歌在剪贴板上泄漏了vc ++解决方案，但没有为C#

Thanks. As said above I wish to get a bmp (bmpx) from a file into a dc (hDC) so that I can use it with bitblt() to crop it.

any ideas of how to go about it? google spills vc++ solutions over Clipboard but none for C#
