Constants

Constants are variables with :const true in their metadata. Joker currently does not recognize them as special; as such, it allows redefining them or their values.

Functions, Macros, and Special Forms

• Decode

  Function v1.0

  (Decode r)
  

  Decode reads a GIF image from r and returns the first embedded
  image as an image.Image.
  
  Go input arguments: (r io.Reader)
  
  Go returns: (image.Image, error)
  
  Joker input arguments: [^go.std.io/Reader r]
  
  Joker returns: [^go.std.image/Image, ^Error]

• DecodeAll

  Function v1.0

  (DecodeAll r)
  

  DecodeAll reads a GIF image from r and returns the sequential frames
  and timing information.
  
  Go input arguments: (r io.Reader)
  
  Go returns: (*GIF, error)
  
  Joker input arguments: [^go.std.io/Reader r]
  
  Joker returns: [^*GIF, ^Error]

• DecodeConfig

  Function v1.0

  (DecodeConfig r)
  

  DecodeConfig returns the global color model and dimensions of a GIF image
  without decoding the entire image.
  
  Go input arguments: (r io.Reader)
  
  Go returns: (image.Config, error)
  
  Joker input arguments: [^go.std.io/Reader r]
  
  Joker returns: [^go.std.image/Config, ^Error]

• Encode

  Function v1.0

  (Encode w m o)
  

  Encode writes the Image m to w in GIF format.
  
  Go input arguments: (w io.Writer, m image.Image, o *Options)
  
  Go returns: error
  
  Joker input arguments: [^go.std.io/Writer w, ^go.std.image/Image m, ^*Options o]
  
  Joker returns: ^Error

• EncodeAll

  Function v1.0

  (EncodeAll w g)
  

  EncodeAll writes the images in g to w in GIF format with the
  given loop count and delay between frames.
  
  Go input arguments: (w io.Writer, g *GIF)
  
  Go returns: error
  
  Joker input arguments: [^go.std.io/Writer w, ^*GIF g]
  
  Joker returns: ^Error
