String.prototype.trimRight()

This function interprets a string value as a sequence of code points, as described in 6.1.4.

The following steps are taken:

  1. Let O be CheckObjectCoercible(this value).
  2. Let S be ToString(O).
  3. ReturnIfAbrupt(S).
  4. Let T be a String value that is a copy of S with trailing white space removed. The definition of white space is the union of WhiteSpace and )LineTerminator. When determining whether a Unicode code point is in Unicode general category “Zs”, code unit sequences are interpreted as UTF-16 encoded code point sequences as specified in 6.1.4.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

You can’t perform that action at this time.
