procedure

(plt-logo [#:height height    
  #:backing-scale backing-scale])  (is-a?/c bitmap%)
  height : (and/c rational? (>=/c 0)) = 256
  backing-scale : (and/c rational? (>/c 0.0))
   = (default-icon-backing-scale)
Returns the PLT logo, rendered in tinted glass and azure metal by the ray tracer that renders icons.

Example:

The default height is the size used for DrRacket splash screen.

procedure

(planet-logo [#:height height    
  #:backing-scale backing-scale])  (is-a?/c bitmap%)
  height : (and/c rational? (>=/c 0)) = 96
  backing-scale : (and/c rational? (>/c 0.0))
   = (default-icon-backing-scale)
Returns an unofficial PLaneT logo. This is used as the PLaneT icon when DrRacket downloads PLaneT packages.
