[static, since 6.0] QSGTexture *QSGVulkanTexture:: fromNative ( VkImage image , VkImageLayout layout , QQuickWindow * window , const QSize & size , QQuickWindow::CreateTextureOptions options = {})

创建新的 QSGTexture wrapping an existing Vulkan image 对象为 window .

本机对象被包裹 (但不归其所有) 通过结果 QSGTexture 。函数调用者负责删除返回的 QSGTexture ,但不会销毁底层本机对象。

此函数目前仅适于 2D RGBA 纹理。

警告: This function will return null if the scene graph has not yet been initialized.

layout must specify the current layout of the image.

使用 options to customize the texture attributes. Only the TextureHasAlphaChannel and TextureHasMipmaps are taken into account here.

size 指定大小 (以像素为单位)。

注意: This function must be called on the scene graph rendering thread.

该函数在 Qt 6.0 引入。
