ClearPixelIterator() clear resources associated with a PixelIterator.

The format of the ClearPixelIterator method is:

  PixelIterator *ClearPixelIterator(PixelIterator *iterator)

A description of each parameter follows:

iterator

The pixel iterator.

DestroyPixelIterator() deallocates resources associated with a PixelIterator.

The format of the DestroyPixelIterator method is:

  PixelIterator *DestroyPixelIterator(PixelIterator *iterator)

A description of each parameter follows:

iterator

The pixel iterator.

IsPixelIterator() returns MagickTrue if the iterator is verified as a pixel iterator.

The format of the IsPixelIterator method is:

  MagickBooleanType IsPixelIterator(const PixelIterator *iterator)

A description of each parameter follows:

iterator

The magick iterator.

NewPixelIterator() returns a new pixel iterator.

The format of the NewPixelIterator method is:

  PixelIterator NewPixelIterator(MagickWand *wand)

A description of each parameter follows:

wand

The magick wand.

PixelClearIteratorException() clear any exceptions associated with the iterator.

The format of the PixelClearIteratorException method is:

  MagickBooleanType PixelClearIteratorException(PixelIterator *wand)

A description of each parameter follows:

wand

The pixel wand.

NewPixelRegionIterator() returns a new pixel iterator.

The format of the NewPixelRegionIterator method is:

  PixelIterator NewPixelRegionIterator(MagickWand *wand,const long x,
    const long y,const unsigned long columns,const unsigned long rows,
    const MagickBooleanType modify)

A description of each parameter follows:

wand

The magick wand.

x,y,columns,rows

These values define the perimeter of a region of pixels.

PixelGetIteratorException() returns the severity, reason, and description of any error that occurs when using other methods in this API.

The format of the PixelGetIteratorException method is:

  char *PixelGetIteratorException(const Pixeliterator *iterator,
    ExceptionType *severity)

A description of each parameter follows:

iterator

The pixel iterator.

severity

The severity of the error is returned here.

PixelGetNextIteratorRow() returns the next row as an array of pixel wands from the pixel iterator.

The format of the PixelGetNextRow method is:

  PixelWand **PixelGetNextRow(PixelIterator *iterator,
    unsigned long *number_wands)

A description of each parameter follows:

iterator

The pixel iterator.

number_wands

The number of pixel wands.

PixelGetPreviousIteratorRow() returns the previous row as an array of pixel wands from the pixel iterator.

The format of the PixelGetPreviousRow method is:

  PixelWand **PixelGetPreviousRow(PixelIterator *iterator,
    unsigned long *number_wands)

A description of each parameter follows:

iterator

The pixel iterator.

number_wands

The number of pixel wands.

PixelResetIterator() resets the pixel iterator. Use it in conjunction with PixelGetNextPixel() to iterate over all the pixels in a pixel container.

The format of the PixelResetIterator method is:

  void PixelResetIterator(PixelIterator *iterator)

A description of each parameter follows:

iterator

The pixel iterator.

PixelSetFirstIteratorRow() sets the pixel iterator to the first pixel row.

The format of the PixelSetFirstIteratorRow method is:

  void PixelSetFirstIteratorRow(PixelIterator *iterator)

A description of each parameter follows:

iterator

The magick iterator.

PixelSetIteratorRow() set the pixel iterator row.

The format of the PixelSetIteratorRow method is:

  MagickBooleanType PixelSetIteratorRow(PixelIterator *iterator,
    const long row)

A description of each parameter follows:

iterator

The pixel iterator.

PixelSetLastIteratorRow() sets the pixel iterator to the last pixel row.

The format of the PixelSetLastIteratorRow method is:

  void PixelSetLastIteratorRow(PixelIterator *iterator)

A description of each parameter follows:

iterator

The magick iterator.

PixelSyncIterator() syncs the pixel iterator.

The format of the PixelSyncIterator method is:

  MagickBooleanType PixelSyncIterator(PixelIterator *iterator)

A description of each parameter follows:

iterator

The pixel iterator.
