LImageIterC<class DataC>
Pointer based image iterator.
include	"amma/Image/LImageIter.hh"
User Level:	Default
Library:	Image
Example:	exIter.cc
Section:	Image.Indexing.Iterators
In Scope:	std

Comments:
NB. This does NOT create a refrence to the image.

A small object.

ImageRectangleC rect;

Image rectangle.

UIntT width;

width of area being iterated.

IndexT row;

Current row.

DataC * placeU;

Ptr to current pixel up from current one.

DataC * place;

Ptr to current pixel. 2st row.

DataC * endOfRow;

Ptr to end of row.

DataC ** img;

table of pointers to image rows

LImageIterC(const ImageC<DataC> & Img)

Construct from an image.
This initalises the iterator to the first pixel in the image, as if First() had been called.

NB. Be VERY carefull because this can break the constant mechanism.

LImageIterC(const LImageIterC<DataC> & Oth)

copy constructor.

LImageIterC(const ImageC<DataC> & Img,const ImageRectangleC & rect)

Construct from an image, and a rectangle.
The iterator will iterate though rectangle 'rect' of image. This initalises the iterator to the first pixel in the image, as if First() had been called.

NB. Be VERY carefull because this can break the constant mechanism.

const LImageIterC<DataC> & operator=(const ImageC<DataC> & Oth)

Assign a new image to iterator.
NB. This will reset iterator to begining of image.

BooleanT First()

Goto first pixel in image.
Returns false if image is empty.

void Next()

Goto next pixel in the image.

void operator++()

Goto next pixel in the image.

void operator++(int)

Goto next pixel in the image.

BooleanT RNext()

Goto next pixel in the image.
Returns TRUE, if next pixels is in same row. FALSE otherwise.

IndexT Col() const

Get current column.
(SLOW) Use ImagPIterC<> if you use this alot.

PixelC Pixel() const

Get current pixel location.
(SLOW) Use ImagPIterC<> if you use this alot.

DataC & Data()

Get value of current pixel.

const DataC & Data() const

Get value of current pixel.

DataC & DataU()

Get value of pixel above current pixel

const DataC & DataU() const

Get value of pixel above current pixel

DataC & DataB()

Get value of pixel left of current pixel

const DataC & DataB() const

Get value of pixel left of current pixel

DataC & operator*()

Get value of current pixel.

const DataC & operator*() const

Get value of current pixel.

DataC * operator->()

Get value of current pixel.

const DataC * operator->() const

Get value of current pixel.

IndexT Row() const

Get current row.

BooleanT IsElm() const

At valid pixel in image ?

operator bool() const

At valid pixel in image ?

BooleanT IsEndOfRow() const

Test if last pixel in row.

DataC * RowPtr(const IndexT & x)

Get start of row.
