    SYNOPSIS

           convert [input-options] input-file [output-options] output-file
    
    
    

    OVERVIEW

           The  convert  program is a member of the ImageMagick(1) suite of tools.
           Use it to convert between image formats as well  as  resize  an  image,
           blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much
           more.
    
           For more information about the convert command, point your  browser  to
           file:///usr/share/doc/ImageMagick-6.7.2//www/convert.html            or

           By default, the image format of 'file' is determined by its magic  num-
           ber.   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.
