Byte * Bitmap::const_iterator::operator*	(	)
throw	(	DviError
	)

Returns the current member of the set of rows returned by the iterator.

This returns a pointer to an array of Byte, with elements [0..W-1] being guaranteed to be valid, where W is the width of the bitmap. If the bitmap is uncropped, this is the total width of the bitmap as returned by method getWidth; if cropped, the width is the difference of the [2] and [0] elements of the array returned by boundingBox.

Returns

pointer to an array of Byte

Exceptions

DviError

if the iterator is dereferenced after it has come to the end

Bitmap::const_iterator & Bitmap::const_iterator::operator++	(	)
throw	(	DviError
	)

Increments the iterator.

If the bitmap is uncropped, all the rows in the bitmap will eventually be iterator over, namely the number of rows returned by method getHeight; if it is cropped, the number of rows returned will be the difference between the [3] and [1] elements of the boundingBox array.

Returns

the iterator

Exceptions

DviError

if the iterator is incremented after it has come to the end

bool Bitmap::const_iterator::operator==

(

const const_iterator &
