The function returns a mapping for a specified font string.

Synopsis

mapping fontToMapping(string font);

Parameters


Parameters	Meaning
font	A font string, e.g. "Arial,-1,17,5,75,0,0,0,0,0,Bold" See also the example at the end of this chapter.

Return value

A mapping with key/value pairs for the specified font.

Description

The function returns a mapping for a specified font string. The returned mapping contains the following key/value pairs of the font:

Table 1. Key/Value Pairs for a font string mapping
Key	Value
"family"	(string)
"pointSize"	(float)
"pixelSize"	(int)
"weight"	(int)
"italic"	(bool)
"underline"	(bool)
"strikeOut"	(bool)
"fixedPitch"	(bool)

Example

The function returns a mapping for the specified font string "Courier New,-1,17,5,50,1,1,0,0,0,Italic"

 main(mapping event)
{
  mapping m = fontToMapping("Courier New,-1,17,5,50,1,1,0,0,0,Italic");
  DebugN("Font string mapping:", m);
}
