creates an image of the text with a user specified outline and an optional dropshadow. Many parameters to set. Check comments in code for parameter descriptions.

-- Outline Text - Imaging Lingo -- creates an image of the text with an -- outline  from -- the member passed or from the string -- passed. -- (c) 2006 by Josh Chunick -- please keep comments intact, -- otherwise use how you like -- a big thank-you to Alex da Franca who -- contributed a good deal to the optimizations -- by setting up the use of the matrices and it's -- parameter, useFastMatrix. The doTrimWhiteSpace -- is now a boolean parameter (thanks to alex) -- because of it's speed cost. -- place this script in a moviescript -- Parameters: -- input - this can be a text member or a property list. -- if you use a property list then the format looks like this: -- [string,[:]] where the property list is a list of text formatting properties in this format: -- eg. ["This is my outline text.", [#font: "Arial", #fontSize: 24, #fontStyle: [#bold], #alignment: #center, #charSpacing: 5]] -- lnSize - integer. The size of the outline as an integer value. -- knockout - boolean. Set to true to make the original text area transparent. -- insideColor - colour object. colour of text. eg. rgb(255,0,0) -- outsideColor - colour of outline and dropshadow. eg. color(0,255,0) -- dsDirection - integer. four possible values corresponding to the direction of the shadow. -- 1: top,left 2: top,right 3: bottom, right 4: bottom, left. -- dsAmount - integer. The amount of offset of the dropshadow. -- doTrimWhiteSpace -- boolean. Trims any whitespace that may be around the text. Default is 1. Speed cost. -- useFastMatrix -- boolean. Uses fast or slow matrix for calculating outline. Default is 1.
