	Skips the given number of scanline rows, which may be fast for some image types.
virtual bool	getEfficientlySkippable () const =0
	Determine if the image may be efficiently skipped via skipScanLines (rather than having to decode every scanline in the skipped range).
Public Member Functions inherited from IEDLObject
virtual const CClassID &	getClassID () const =0
	Returns class ID of IEDLObject.
virtual bool	init (CClassParams *pData)
	The init() method is called to perform any post-construction initialization of an IEDLObject that has been created by the EDL class factory, before it is actually returned by the factory.
virtual bool	clone (IEDLObjectPtr &ptrObject, IEDLClassFactory *pFactory)
	Create a copy of EDLObject.
Public Member Functions inherited from IRCObject
virtual void	addRef () const =0
	Increases the reference count of the actual object pointed to. This would take place during an assignment or copying.
virtual bool	decRef () const =0
	Decreases the reference count of the actual object pointed to. When the reference count falls to Zero, it deletes the actual object pointed to.
virtual int32	getRefCount () const =0
	Retrieve the current reference count of the actual object pointed to.

Detailed Description

IImageFrame encapsulates an EDL image with its details.

Constructor & Destructor Documentation

◆ ~IImageFrame()

virtual IImageFrame::~IImageFrame ( )

inlinevirtual

Member Function Documentation

◆ getBPS()

virtual uint8 IImageFrame::getBPS ( ) const

pure virtual

Gets the bits per sample of the image.

Returns: uint8 Returns the image bits from sample.

◆ getColorSpace()

virtual IDOMColorSpacePtr IImageFrame::getColorSpace ( ) const

pure virtual

Gets the color space.

Returns: IDOMColorSpacePtr The colorspace of the image.

◆ getEfficientlySkippable()

virtual bool IImageFrame::getEfficientlySkippable ( ) const

pure virtual

Determine if the image may be efficiently skipped via skipScanLines (rather than having to decode every scanline in the skipped range).

Returns: bool true if the image has an efficient skipScanLines implementation.

Implemented in IImageFrameWriter.

◆ getExtraChannelType()

virtual eImageExtraChannelType IImageFrame::getExtraChannelType ( ) const

pure virtual

Gets the type of information contained in the extra channel.

Returns: eImageExtraChannelType Returns the type of information in the extra channel.

◆ getHasAlphaChannel()

virtual bool IImageFrame::getHasAlphaChannel ( ) const

inlinevirtual

Indicates if the image has an alpha mask.

Returns: bool. Returns an indication of alpha mask present in the image.

◆ getHasMask()

virtual bool IImageFrame::getHasMask ( bool & isNoisy ) const

inlinevirtual

Indicates if the image has a mask (i.e. a binary alpha channel)

Parameters

isNoisy An indicator that the alpha channel has binary values and so is acting as a mask.

Returns: bool. Returns an indication of mask present in the image

◆ getHeight()

virtual uint32 IImageFrame::getHeight ( ) const

pure virtual

Gets the height of the image.

Returns: uint32 Returns the image height.

◆ getNumChannels()

virtual uint8 IImageFrame::getNumChannels ( ) const

inlinevirtual

Gets the total number of image channels (including extra channels)

Returns: uint8 Returns the total number of image channels.

◆ getNumExtraChannels()

virtual uint8 IImageFrame::getNumExtraChannels ( ) const

inlinevirtual

Gets the number of image extra channels (for example an alpha or mask)

Returns: uint8 Returns the number of image extra channels.

◆ getRawBytesPerRow()

virtual uint32 IImageFrame::getRawBytesPerRow ( ) const

pure virtual

Gets the image row size in bytes, which may include padding space.

Returns: uint32 The image row size in bytes

◆ getWidth()

virtual uint32 IImageFrame::getWidth ( ) const

pure virtual

Gets the width of the image.

Returns: uint32 Returns the image width.

◆ getXResolution()

virtual double IImageFrame::getXResolution ( ) const

pure virtual

Gets the resolution of the image in the X direction.

Returns: double The resolution in the X direction.

◆ getYResolution()

virtual double IImageFrame::getYResolution ( ) const

pure virtual

Gets the resolution of the image in the Y direction.

Returns: double The resolution in the Y direction.

◆ readScanLine()

virtual void IImageFrame::readScanLine	(	void *	pRow,
		size_t	bufferSize )

pure virtual

Gets an image row scanline (of size given by getRawBytesPerRow())

Parameters

pRow	The buffer in which the row scanline will be copied into.
bufferSize	The size of the buffer. A check will be made that the buffer is large enough to receive the scanline before it is read.

Implemented in IImageFrameWriter.

◆ skipScanLines()

virtual void IImageFrame::skipScanLines ( uint32 skipCount )

inlinevirtual

Skips the given number of scanline rows, which may be fast for some image types.

Parameters

skipCount The number of scanlines to skip..
