Hi Mighty Monks,

A few months ago, I had to deal with GD. Most GD functions expect the colours to be given as lists of three figures (amounts of red, green and blue, in that order, as I'm sure you had already guessed). I for one preferred to store my colours as numbers in a hash, using the handy 0xnnnnnn notation. I thus needed a function that would take an integer as argument and return the three elements: a good opportunity for a bit of golfing (and obfuscation if you care to...).

The function assumes the arguments is a valid hexa triplet, i.e. an integer between 0 and 0xFFFFFF.

My entry (43 chars only counting within the braces):

sub hexa_triplet { map eval"0x$_",sprintf('%06x',pop)=~/(..)/g }

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
