问题描述
我有一个C ++ Builder(Rad Studio Berlin)项目设置来使用Direct2d.画布绘制与TDirect2DCanvas配合得很好，这表明Direct2D正确链接.一切都呈现流畅.但是，我需要使用矩阵.尝试链接时出现链接错误.例如，当我尝试:
I've got a C++ Builder (Rad Studio Berlin) project setup to use Direct2d. Canvas drawing works just fine with the TDirect2DCanvas which would indicate Direct2D is linking properly. Everything renders smoothly. However, I need to use a matrix. I get linking error when I try to. For example, when try I:
canvas->RenderTarget->SetTransform(D2D1::Matrix3x2F::Rotation(15.0, D2D1PointF(100, 100)));
...我收到以下链接错误:
...I get the following linking error:
[ilink32 Error] Error: Unresolved external 'D2D1MakeRotateMatrix' referenced from C:\DP\TRUNK\SRC\CLIENTSIDE\APPLICATIONS\VIEWER\WIN32\DEBUG\MIMAGE.OBJ
如果我仅包含标头，则应该已经设置了
C ++构建器以针对Direct2d进行链接.谁能帮助我以C ++ Builder的方式链接到适当的文件?
C++ builder was supposed to already be setup to link against direct2d if I just include the headers. Can anyone help me link against the appropriate files in the C++ Builder way?
推荐答案
我从其他来源找到了解决方案.在这里:
I found the solution from a different source. Here it is:
经过研究，尚未确定此问题是错误.
After some research, this issue has not been determined to be a bug.
解决方案是(如上所述)将D2D1.lib添加到项目中，或在代码中静态引用它:
The solution is to either (as I mentioned previously) add the D2D1.lib to the project, or statically reference it in code:
// as long as D2D1.lib is on the library search path, it should be found
#pragma comment(lib,"D2D1.lib")
希望这可以澄清问题，
