%  Use the mogrify program to resize an image, blur, crop, despeckle, dither,

%  convert except that the original image file is overwritten (unless you
%  change the file suffix with the -format option) with any changes you
%  request.
%
%  This embeds the legacy command-line parser as opposed to operation.c which
%  embeds the modern parser designed for the execution in a strict one option
%  at a time manner that is needed for 'pipelining and file scripting' of
%  options in IMv7.

%
%  MogrifyImage() applies simple single image processing options to a single
%  image that may be part of a large list, but also handles any 'region'
%  image handling.
%
%  The image in the list may be modified in three different ways...
%
%    * directly modified (EG: -negate, -gamma, -level, -annotate, -draw),
%    * replaced by a new image (EG: -spread, -resize, -rotate, -morphology)
%    * replace by a list of images (only the -separate option!)
%
%  In each case the result is returned into the list, and a pointer to the
%  modified image (last image added if replaced by a list of images) is
%  returned.
%
%  ASIDE: The -crop is present but restricted to non-tile single image crops
%
%  This means if all the images are being processed (such as by
%  MogrifyImages(), next image to be processed will be as per the pointer
%  (*image)->next.  Also the image list may grow as a result of some specific
%  operations but as images are never merged or deleted, it will never shrink
%  in length.  Typically the list will remain the same length.
%
%  WARNING: As the image pointed to may be replaced, the first image in the
%  list may also change.  GetFirstImageInList() should be used by caller if
%  they wish return the Image pointer to the first image in list.
%
%
%  The format of the MogrifyImage method is:
%
%      MagickBooleanType MogrifyImage(ImageInfo *image_info,const int argc,
%        const char **argv,Image **image)
%
%  A description of each parameter follows:
%
%    o image_info: the image info..
%
%    o argc: Specifies a pointer to an integer describing the number of
%      elements in the argument vector.
%
%    o argv: Specifies a pointer to a text array containing the command line
%      arguments.
%
%    o image: the image.
%
%    o exception: return any errors or warnings in this structure.

%  MogrifyImageCommand() transforms an image or a sequence of images. These
%  transforms include image scaling, image rotation, color reduction, and
%  others. The transmogrified image overwrites the original image.
%
%  The format of the MogrifyImageCommand method is:
%
%      MagickBooleanType MogrifyImageCommand(ImageInfo *image_info,int argc,
%        const char **argv,char **metadata,ExceptionInfo *exception)
%
%  A description of each parameter follows:
%
%    o image_info: the image info.
%
%    o argc: the number of elements in the argument vector.
%
%    o argv: A text array containing the command line arguments.
%
%    o metadata: any metadata is returned here.
%
%    o exception: return any errors or warnings in this structure.

%  MogrifyImageInfo() applies image processing settings to the image as

%    o image_info: the image info..
%
%    o post: If true, post process image list operators otherwise pre-process.
%
%    o argc: Specifies a pointer to an integer describing the number of
%      elements in the argument vector.
%
%    o argv: Specifies a pointer to a text array containing the command line
%      arguments.
%
%    o images: pointer to a pointer of the first image in image list.
%
%    o exception: return any errors or warnings in this structure.
