NAME
       mogrify - resize an image, blur, crop, despeckle, dither, draw on,
       flip, join, re-sample, and much more. Mogrify overwrites the original
       image file, whereas, convert(1) writes to a different image file.

SYNOPSIS
       mogrify [options] input-file

OVERVIEW
       The mogrify program is a member of the ImageMagick(1) suite of tools.
       Use it to resize an image, blur, crop, despeckle, dither, draw on,
       flip, join, re-sample, and much more. This tool is similar to
       convert(1) except the original image file is overwritten with any
       changes you request.

       By default, the image format of `file' is determined by its magic
       number.  To specify a particular image format, precede the filename
       with an image format name and a colon (i.e. ps:image) or specify the
       image type as the filename suffix (i.e. image.ps).  Specify 'file' as
       '-' for standard input or output.
