Function

Smooths text for on-screen display..

Syntax


caption = LaTeXText(object, alias_factor, background);

Inputs

Name	Type	Default	Description
`object`	field	none	text object
`alias_factor`	scalar	0.5	antialias factor (0-1)
`background`	vector	[0 ,0, 0]	background colour

Outputs

Name	Type	Description
`output`	color field	antialiased object

Functional Details

The caption produced is aligned in parallel with the screen.

`object`	input text object. At present this must be a LaTeX formatted text object. Standard opendx text objects have bizarre boundaries which result in surface defects when anti-aliased using this macro - this is either a bug or a feature!
`alias_factor`	the antialias factor between 0.0 and 1.0. If this factor is x then a single pixel line of colour (1-x)b+(x)f is drawn around the text character boundaries, simulating antialiasing.
`background`	background colour as a vector.

Notes:

At present the input text must be a LaTeX formatted text object. Standard opendx text objects have bizarre boundaries which result in surface defects when anti-aliased using this macro - this is either a bug or a feature!
The text background colour must be uniform over the text to be antialiased - TextAlias cannot at present adjust for colour changes in the background. However, if the background is largely of one colour you might get away with it.
Because the antialiasing line is always precisely one pixel wide, the smaller the pixel height of text, the greater the relative amount of antialiasing - exactly as it should be.
