Method Details

startLines

public void startLines()

Description copied from interface: RectIter

Sets the iterator to the first line of its bounding rectangle. The pixel and band offsets are unchanged.

Specified by:

startLines in interface RectIter

Overrides:

startLines in class RectIterFallback

nextLine

public void nextLine()

Description copied from interface: RectIter

Sets the iterator to the next line of the image. The pixel and band offsets are unchanged. If the iterator passes the bottom line of the rectangles, calls to get() methods are not valid.

Specified by:

nextLine in interface RectIter

Overrides:

nextLine in class RectIterFallback

jumpLines

public void jumpLines(int num)

Description copied from interface: RectIter

Jumps downward num lines from the current position. Num may be negative. The pixel and band offsets are unchanged. If the position after the jump is outside of the iterator's bounding box, an IndexOutOfBoundsException will be thrown and the position will be unchanged.

Specified by:

jumpLines in interface RectIter

Overrides:

jumpLines in class RectIterFallback

startPixels

public void startPixels()

Description copied from interface: RectIter

Sets the iterator to the leftmost pixel of its bounding rectangle. The line and band offsets are unchanged.

Specified by:

startPixels in interface RectIter

Overrides:

startPixels in class RectIterFallback

nextPixel

public void nextPixel()

Description copied from interface: RectIter

Sets the iterator to the next pixel in image (that is, move rightward). The line and band offsets are unchanged.

This method may be used in conjunction with the method finishedPixels. Or the method nextPixelDone, which sets the iterator to the next pixel and checks the bound, may be used instead of this method.

Specified by:

nextPixel in interface RectIter

Overrides:

nextPixel in class RectIterFallback

jumpPixels

public void jumpPixels(int num)

Description copied from interface: RectIter

Jumps rightward num pixels from the current position. Num may be negative. The line and band offsets are unchanged. If the position after the jump is outside of the iterator's bounding box, an IndexOutOfBoundsException will be thrown and the position will be unchanged.

Specified by:

jumpPixels in interface RectIter

Overrides:

jumpPixels in class RectIterFallback

startBands

public void startBands()

Description copied from interface: RectIter

Sets the iterator to the first band of the image. The pixel column and line are unchanged.

Specified by:

startBands in interface RectIter

Overrides:

startBands in class RectIterFallback

nextBand

public void nextBand()

Description copied from interface: RectIter

Sets the iterator to the next band in the image. The pixel column and line are unchanged.

Specified by:

nextBand in interface RectIter

Overrides:

nextBand in class RectIterFallback
