Turtle options

Build Status

This package provides additional command line options for Turtle.

Percentage

Parse a percentage (20%). The result is a floating point number (Float), corresponding to the given percentage divided by 100.

Scale

Parse a scaling option in different ways. You can specify a size (480x320), a width (480x) or a height (x320) or a percentage (50% or 0.5, needs to be positive).

Quality

Parse a quality option. This can be a percentage or a keyword (verylow, low, mediumlow, medium, mediumhigh, high, best). The keywords are mapped to a percentage according to the following table:

Keyword Percentage
verylow 10%
low 20%
mediumlow 35%
medium 50%
mediumhigh 65%
high 80%
veryhigh 90%
best 100%

Timecode

Parse a timecode. A timecode is made of a number of hours, minutes, seconds and milliseconds. The time code can be given in different formats. You don’t have to give a number of seconds or minutes inferior to 60. For example if you give 75 minutes, it will be interpreted as 1 hour and 15 minutes. You can also provide a number of milliseconds superior to 1000. The only required number is the number of seconds. The following table gives examples of valid timecodes and how they are interpreted:

Timecode Result
3 3 secs
75 1 min 15 secs
17:12 17 mins 12 secs
80:23 1 hour 20 mins 23 secs
54:32:10 54 hours 32 mins 10 secs
43.7 43 secs 700 millisecs
4:13.85 4 mins 13 secs 850 millisecs
7:4:13.437 7 hours 4 mins 13 secs 437 millisecs
5.2150 7 secs 150 milliseconds

You can also use the 00h00m00s000 format if you prefer. The same rules apply:

1h34m12s345 gives 1 hour 34 mins 12 secs and 345 millisecs

A timecode can be negative:

-3:45 (or -3m45) gives minus 3 mins and 45 secs
