.convert(input, output) ⇒ Object

Public: Converts a TTF font file to an EOT font.

input - the input TTF font as a String (representing a path) or IO object

(responding to #read).

output - the output destination as a String (representing a path) or IO

object where the EOT font will be written.

Examples:

TTF2EOT.convert("input.ttf", "output.eot")
# => #<File:output.eot>

input = StringIO.new(File.read("input.ttf"))
output = StringIO.new
TTF2EOT.convert(input, output)
# => #<StringIO:0x007f815a83a210>

Returns the output IO object. Raises TTF2EOT::ConversionError if the input data is invalid.
