Turtlefont is a small vector graphics font file format with an example font. It uses simple turtle graphics rendering which allows flexible scaling.
TO BE DONE
This project also provides some font specimen examples:
Mime type: application/x-turtle-font
TO BE DONE
Mime type: text/x-turtle-font
The demo features an example font format which allows the definition of multiple glyphs.
The format is line based and does not allow any other lines except for lines in the following format:
C:CODE\n
C
is the character for which a glyph should be defined.
CODE
is a glyph definition in the format specified in Glyph Format.
\n
is a newline character.
Turtlefont has a simple glyph description language which contains commands with or without parameters. A command is a single character, a parameter as well.
Parameters can only be numeric with a pretty restricted format: It is only a single hexadecimal character in the range of 0
to F
. If a negative number is needed, the character can be prefixed with a -
.
Whitespace is ignored.
