ImageMagick: MagickWand, C API for ImageMagick: Pixel Iterator Methods
Author: ImageMagick Studio LLC
Description: ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you can freely use, copy, modify, and distribute. Its license is compatible with the GPL. It runs on all major operating systems. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: MagickCore (C), MagickWand (C), ChMagick (Ch), Magick++ (C++), JMagick (Java), L-Magick (Lisp), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (P [cell cut: 1167 characters, first 1000 kept]

## ClearPixelIterator 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 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 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 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 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 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. ## PixelGetCurrentIteratorRow PixelGetCurrentIteratorRow() returns the current row as an array of pixel wands from the pixel iterator. The format of the PixelGetCurrentIteratorRow method is:
      PixelWand **PixelGetCurrentIteratorRow(PixelIterator *iterator,
        unsigned long *number_wands)
A description of each parameter follows: ##### iterator The pixel iterator. ##### number_wands The number of pixel wands. ## PixelGetIteratorException 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. ## PixelGetIteratorRow PixelGetIteratorRow() returns the crurent pixel iterator row. The format of the PixelGetIteratorRow method is:
      MagickBooleanType PixelGetIteratorRow(PixelIterator *iterator)
A description of each parameter follows: ##### iterator The pixel iterator. ## PixelGetNextIteratorRow PixelGetNextIteratorRow() returns the next row as an array of pixel wands from the pixel iterator. The format of the PixelGetNextIteratorRow method is:
      PixelWand **PixelGetNextIteratorRow(PixelIterator *iterator,
        unsigned long *number_wands)
A description of each parameter follows: ##### iterator The pixel iterator. ##### number_wands The number of pixel wands. ## PixelGetPreviousIteratorRow PixelGetPreviousIteratorRow() returns the previous row as an array of pixel wands from the pixel iterator. The format of the PixelGetPreviousIteratorRow method is:
      PixelWand **PixelGetPreviousIteratorRow(PixelIterator *iterator,
        unsigned long *number_wands)
A description of each parameter follows: ##### iterator The pixel iterator. ##### number_wands The number of pixel wands. ## PixelResetIterator PixelResetIterator() resets the pixel iterator. Use it in conjunction with PixelGetNextIteratorRow() 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 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 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 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 PixelSyncIterator() syncs the pixel iterator. The format of the PixelSyncIterator method is:
