ImgFieldC<class PixTypeT>
Template class for video fields
include	"amma/ImgField.hh"
User Level:	Default
Library:	MvideoIntl
Example:	exIntlIter.cc
Section:	Image.Video.Interlace Image.Image_Representations
In Scope:	std

Comments:
An image template class containing only rows for the current field. This class does not inherit from ImageC, although its member functions behave in an analogous manner to those in ImageC. Use FieldIterC as an iterator.

public VidIntlBodyC

ImgFieldC()

Default constructor

ImgFieldC(const ImageC<PixTypeT> & img,IndexC fif,const VidIntlBodyC & intl)

Constructor tthat deinterlaces field from frame, using interlace params

ImgFieldC(const ImageRectangleC & fr,IndexC fif,const VidIntlBodyC & intl)

Constructor of empty field from frame rectangle & interlace params

ImgFieldC(const ImageRectangleC & fr,ImgFieldC<PixTypeT> other)

Constructor of empty field from frame rectangle, using interlace params from "other"

ImgFieldC(IndexC fif,const VidIntlBodyC & intl,ImageC<PixTypeT> & img,const ImageRectangleC & frame = ImageRectangleC())

Constructor repackages image as field, using field no. in frame and interlace info. I.e. the resulting field is identical to "img" apart from the row numbering.
The optional "frame" argument specifies the rectangle of the containing frame, e.g. if the fields within a frame do not have an identical number of rows. "frame" and "img" sizes must be consistent; i.e. the rows from "img" should occupy precisely all of the appropriate field rows in "frame".

const ImageC<PixTypeT> Image() const

returns plain image of field, with rows numbered consecutively

ImageC<PixTypeT> Image()

returns plain image of field, with rows numbered consecutively

IndexC FieldInFrame() const

returns field no. within current frame;

BooleanT FirstInFrame() const

true if first field in frame (i.e. it includes the top row of the frame)

BooleanT LastInFrame() const

true if last field in frame

BooleanT IsValid() const

true if image component is valid

BooleanT IsEmpty() const

true if image component contains no data

IndexT TRow() const

top row of current frame

IndexT BRow() const

bottom row of current frame

IndexT LCol() const

leftmost column of field

IndexT RCol() const

rightmost column of field

const RangeBufferAccessC<PixTypeT> operator[](IndexT r) const

Const. access to the row of pixels, based on row no. in frame

RangeBufferAccessC<PixTypeT> operator[](IndexT r)

Access to the row of pixels, based on row no. in frame

const PixTypeT & operator[](const Index2dC & pxl) const

Returns the content of the pixel.

PixTypeT & operator[](const Index2dC & pxl)

Returns the content of the pixel.

const PixTypeT & operator[](const PixelC & pxl) const

Returns the content of the pixel.

PixTypeT & operator[](const PixelC & pxl)

Returns the content of the pixel.

const ImageRectangleC & Rectangle() const

returns rectangle of current frame

BooleanT IsInterlaced() const

Is Stream interlaced ? (i.e. >1 field per frame)

UIntT FieldsPerFrame() const
