PerceptionVideoFrameAllocator 构造函数

定义

命名空间:

Windows.Devices.Perception.Provider

使用 IPerceptionFrameProvider 所需的属性初始化新的 PerceptionVideoFrameAllocator，以创建通过 PerceptionFrameProviderManagerService：:P ublishFrameForProvider 发布的 PerceptionFrame。

public:
 PerceptionVideoFrameAllocator(unsigned int maxOutstandingFrameCountForWrite, BitmapPixelFormat format, Size resolution, BitmapAlphaMode alpha);

/// [Windows.Foundation.Metadata.Deprecated("PerceptionVideoFrameAllocator may be unavailable after Windows Creator Update. Please refer to AVStream on MSDN.", Windows.Foundation.Metadata.DeprecationType.Deprecate, 262144, "Windows.Foundation.UniversalApiContract")]
 PerceptionVideoFrameAllocator(uint32_t const& maxOutstandingFrameCountForWrite, BitmapPixelFormat const& format, Size const& resolution, BitmapAlphaMode const& alpha);

[Windows.Foundation.Metadata.Deprecated("PerceptionVideoFrameAllocator may be unavailable after Windows Creator Update. Please refer to AVStream on MSDN.", Windows.Foundation.Metadata.DeprecationType.Deprecate, 262144, "Windows.Foundation.UniversalApiContract")]
public PerceptionVideoFrameAllocator(uint maxOutstandingFrameCountForWrite, BitmapPixelFormat format, Size resolution, BitmapAlphaMode alpha);

function PerceptionVideoFrameAllocator(maxOutstandingFrameCountForWrite, format, resolution, alpha)

Public Sub New (maxOutstandingFrameCountForWrite As UInteger, format As BitmapPixelFormat, resolution As Size, alpha As BitmapAlphaMode)

参数

maxOutstandingFrameCountForWrite

UInt32

unsigned int

uint32_t

这是 FrameProvider 以帧速率生成其 * 帧所需的未处理缓冲区数。 建议至少为 2。

format

BitmapPixelFormat

描述帧字节格式的 Windows：：Graphics：：Imaging：：BitmapPixelFormat。

resolution

Size

帧的分辨率（以像素为单位）。

alpha

BitmapAlphaMode

描述如何处理像素透明度的 Windows：：Graphics：：Imaging：：BitmapAlphaMode。

属性
