详细说明

成员函数文档

[static, since 6.0] QSGTexture *QSGD3D11Texture::fromNative(void *texture, QQuickWindow *window, const QSize &size, QQuickWindow::CreateTextureOptions options = {})

创建一个新的QSGTexture ,将现有的 Direct 3D 11texture 对象包装为window

生成的QSGTexture 封装了本地对象,但不拥有本地对象。函数的调用者负责删除返回的QSGTexture ,但这不会破坏底层的本地对象。

该函数目前仅适用于 2D RGBA 纹理。

警告: 如果场景图尚未初始化,此函数将返回空值。

使用options 可自定义纹理属性。这里只考虑了 TextureHasAlphaChannel 和 TextureHasMipmaps。

size 指定以像素为单位的大小。

注意: 此函数必须在场景图渲染线程上调用。

此函数在 Qt 6.0 中引入。

[pure virtual] void *QSGD3D11Texture::nativeTexture() const

返回 ID3D11Texture2D 对象。
