Are you asking about the old BGI textout() graphics function?

Give me a minute -- gotta get my daughter some cereal.


Okay, the most basic algorithm considers only a maximum line width -- in your case, in pixels.

You'll need the textwidth() function to find out how many pixels wide a specific string will display.

Break your text into words (break on spaces) and find the most words at the beginning of a line that has a text width less than or equal to your maximum line width. Write that, then increment your Y by the textheight() for that line.

Remove the stuff you just wrote from the beginning of the string and repeat while there is text to write.

Hope this helps.
