Function Documentation

◆ a_Color_parse()

int32_t a_Color_parse ( const char *  str,
int32_t  default_color,
int *  err 
)

Parse a color string.

  • If the string begins with # or with 0x, return the color number (with 'RGB' expanded to 'RRGGBB').
  • Else search the set of named colors.
  • As a last resort, treat it as bare hex as in the first case.
Returns
  • Parsed color if successful,
  • default_color on error.

"err" argument:

  • 0 if a color beginning with '#' is successfully parsed or the color is a recognized word.
  • 1 if the color is bare hex or can't be parsed at all.
  • 2 if a color beginning with 0[xX] is successfully parsed.
