Description
standard-fish fails for small values with an unfortunate error that unlike a normal error points elsewhere in the code.
standard-fish is defined at pict-lib/pict/private/utils.rkt
options:
- check args are valid w>5 , h>1?
- modify standard fish to accept any numbers, including zero and negative.
#lang racket
(require pict)
