成员函数文档编制

◆  GetFootageName()

Filename GetFootageName ( ) const

Retrieves the filename of the footage (the first frame if an image sequence).

返回
The filename.

◆  GetFirstFrameNumber()

Int32 GetFirstFrameNumber ( ) const

Retrieves the frame number of the first frame in the footage.

返回
The first frame number. -1 if no footage loaded.

◆  GetLastFrameNumber()

Int32 GetLastFrameNumber ( ) const

Retrieves the frame number of the last frame in the footage.

返回
The last frame number. -1 if no footage loaded.

◆  GetResolutionWidthPix()

Int32 GetResolutionWidthPix ( Bool   originalRes ) const

Queries the width in pixels of the footage.

参数
[in] originalRes 若 true , the returned pixel coordinates are for the original footage. If false , the returned pixel coordinates are for the downsampled footage.
返回
The width of footage in pixels.

◆  GetResolutionHeightPix()

Int32 GetResolutionHeightPix ( Bool   originalRes ) const

Queries the height in pixels of the footage.

参数
[in] originalRes 若 true , the returned pixel coordinates are for the original footage. If false , the returned pixel coordinates are for the downsampled footage.
返回
The height of footage in pixels.

◆  GetResolutionAspectRatio()

Float GetResolutionAspectRatio ( ) const

Queries the aspect ratio of the horizontal to vertical resolution. Ignores pixel aspect ratio.

返回
The aspect ratio from resolution.

◆  GetImageAspectRatio()

Float GetImageAspectRatio ( ) const

Queries the aspect ratio of the footage including effects of pixel aspect ratio.

注意
GetImageAspectRatio() == GetResolutionAspectRatio() * GetPixelAspectRatio()
返回
The aspect ratio of footage.

◆  GetPixelAspectRatio()

Float GetPixelAspectRatio ( ) const

Queries the pixel aspect ratio of the footage.

返回
The pixel aspect ratio.

◆  GetDownsamplingFactor()

Float GetDownsamplingFactor ( ) const

Queries the downsampling factor used for the footage.

返回
The downsampling factor.

◆  Alloc()

static MtFootageData * Alloc ( )
static

Internal .

◆  Free()

static void Free ( MtFootageData *&  p )
static

Destructs MtFootageDatas allocated with Alloc() 。使用 AutoAlloc to automate the allocation and destruction based on scope.

参数
[in,out] p The MtFootageData to destruct. If the pointer is nullptr nothing happens. The pointer is assigned nullptr afterwards.
