Actually changing text size with OCaml Graphics

问题

I was wondering how to set text size in OCaml. I tried Graphics.set_text_size which should do the deal I guess.

But whether I put set_text_size 200 or set_text_size 20 doesn't change a thing…

回答1:

Graphics.set_text_size is not implemented yet. https://github.com/ocaml/ocaml/blob/trunk/otherlibs/graph/graphics.ml#L165 https://github.com/ocaml/ocaml/blob/trunk/otherlibs/graph/text.c#L36 https://github.com/ocaml/ocaml/blob/trunk/otherlibs/win32graph/draw.c#L350

maybe for now, Graphics.set_text_size is not implemented yet.

But, you can use: set_font

set_font "-misc-dejavu sans mono-bold-r-normal--256-0-0-0-m-0-iso8859-1";

this can set font size
