在 D3D 上正确调整 D2D 的大小



我在调整 D2D 渲染目标的大小时遇到问题，而不是 D3D11。我制作了调整交换链缓冲区大小的功能。它工作得很好，但是当我激活 D2D 时，调整大小就坏了。

当我缩小窗口时，所有网格都会从窗口中消失 - 只显示文本。当我制作更大的网格时 - 渲染网格，但比例不正确，尽管我重新创建了投影矩阵。

我的问题是 - 如何在窗口大小更改后正确调整 D2D 呈现目标和文本的大小？

这是我创建 D3D11Device、swapchain1 和 D2D 的代码。

我在事件WM_SIZE调整缓冲区大小：

    case WM_SIZE:
    {
        int Width = LOWORD(lparam);
        int Height = HIWORD(lparam);
        WCHAR* str = NULL;
        if (wparam == SIZE_RESTORED)
        {
            if (system->application)
            {
                system->application->d3d11->ResizeSwapChain();
                system->application->d3d11->ResizeD2DBuffer();
                system->application->cameraDX_Free->perspective(system->application->cameraDX_Free->m_fovx,
                    static_cast<float>(Width) / static_cast<float>(Height),
                    system->application->cameraDX_Free->m_znear,
                    system->application->cameraDX_Free->m_zfar);
            }
        }
    }

要正确调整 D2D 的大小，您首先需要删除所有 d2d 资源，然后在调整大小交换链后再次重新创建所有资源。
