Image2IterC<class Data1C,class Data2C>
Pointer based image iterator for image pairs.
include	"amma/Image2Iter.hh"
User Level:	Default
Library:	Image
Example:	exIter.cc
Section:	Image.Indexing.Iterators
In Scope:	std

Comments:
NB. This does NOT hold a refrence to any of the images!

Allows FAST iteration over a pair of images. It is intended for implementing image processing operations which require access to a pixel in two images.

Note that the two images do not need to be of the same type.

protected ImageIterC<class DataC>

Image3IterC

Image2IterC()

Default constructor

Image2IterC(const ImageC<Data1C> & img1,const ImageC<Data2C> & img2)

Construct from input and output images.

Image2IterC(const ImageC<Data1C> & img1,const ImageC<Data2C> & img2,const ImageRectangleC & rect)

Construct from input and output images.
Interates through rectangle 'rect', which MUST be within both images.

Image2IterC(const Image2IterC & Oth)

Copy constructor.

BooleanT First()

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

void Next()

Goto next pixel in image.

BooleanT RNext()

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

void operator++()

Goto next pixel in the image.

void operator++(int)

Goto next pixel in the image.

Data1C & Data1()

Access pixel from image 1

Data2C & Data2()

Access pixel from image 2

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.

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.
