Hi Davide, Thank you. I don't know how much you know about hinting vs rendering. You seem to be confused about FT_LOAD flags.
> FT_Load_Char(face, 'e', FT_LOAD_DEFAULT | FT_LOAD_TARGET_LIGHT | > FT_LOAD_MONOCHROME | FT_LOAD_NO_BITMAP); FT_LOAD_DEFAULT is just 0 and is meaningless in the OR-chain. FT_LOAD_NO_BITMAP mean no embedded bitmaps, which Arial does not have, if I am not mistaken FT_LOAD_MONOCHROME is a selector of rendering algorithm, but you postpone it until later. It has no effect FT_LOAD_TARGET_LIGHTis the only flag that does a lot here: it enables autohinting but only vertically, bytecode is disabled. As a result you might indeed use wrong hinting (or without horizontal hinting) for a mono rendering. Please try FT_LOAD_TARGET_MONO as our documentation clearly suggests for monochrome rendering. See https://freetype.org/freetype2/docs/reference/ft2-base_interface.html#ft_load_xxx. > FT_Render_Glyph(face->glyph, FT_RENDER_MODE_MONO); You might argue that it used to work. I really do not know how. Again, you should get an Ok output with just FT_LOAD_TARGET_MONO do not make it more complicated than that.
