CPMarkup

Markup specification that can be used to convert a sequence of characters to the sequence of pixels based on this specification.

Each specification has mandatory default foreground and optional background colors. It also has a list of markup elements (potentially empty) where each element has opening and closing tag and a function that takes a character and returns pixel.

Here's an example of defining the markup:

   val markup = CPMarkup(
       C_GREEN,
       Option(C_BLACK),
       Seq(
           CPMarkupElement("<$", "$>", _&&(C_RED, C_WHITE)),
           CPMarkupElement("{#", "#}", _&&(C_BLUE, C_YELLOW)),
           CPMarkupElement("(?", "?)", _&&(C_BLACK, C_WHITE))
       )
   )

Once defined this markup can be used to convert a string ito sequence of pixels and then create an image:

   val pxs = markup.process("text <$ red on white (? black on white ?)$> {# blue on yellow #}")
   val img = CPArrayImage(pxs, bgPx, align = -1) // Left-aligned image.
