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:
> (plt-logo)
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.
Examples:
> (planet-logo)
> (planet-logo #:height (default-icon-height))
procedure
(stepper-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 the algebraic stepper logo.
Example:
> (stepper-logo)
