SYNOPSIS
     sips [image-functions] imagefile ...
     sips [profile-functions] profile ...

DESCRIPTION
     This tool is used to query or modify raster image files and ColorSync ICC
     profiles.  Its functionality can also be used through the "Image Events"
     AppleScript suite.  It also supports executing JavaScript to either
     modify or generate images.

JavaScript
     HTML Canvas objects can be created and used to create a 2D drawing
     context.  The commands for drawing into the context are well documented
     elsewhere.  This section will describe the sips global object and other
     interesting classes.

     Global variable (sips) properties
     images
           Valid images passed as arguments converted into an array of Image
           objects
     arguments
           Arguments passed into the program as an array of strings
     size  Recommended size for output. Setting the crop or resample flags
           will set this value.
     longestEdge
           If specified, the value of the -Z/--resampleHeightWidthMax option.
           [default: 0]
     outputPath
           Output directory [default: current directory]

     Image Object
     name  Name of image
     size  Size of image (pixels)
     properties
           Image properties
     getProperty(name)
           Return the image property for name, if any.
     sizeToFitLongestEdge(length)
           Return the size that will contain the image with the longest edge
           set to length. Maintains aspect ratio.

     Output Object
     new Output(context, name[, type])
           Output the context to disk with name and optional type (extension
           or UTI).
     addToQueue()
           Adds the output to the queue to be written to disk.

     Functions
     print(str)
           Output to standard output. Equivalent to console.log(str).
