Draw Text

[syvkal]

Does anyone know the scripting for the draw_text command in the bitmap class?

This is very important for a script I'm making.

Thanks in advance ^_^

Read the help file

bitmap.draw_text(x, y, width, height, text, align)
bitmap.draw_text(rect, text, align)

You specify a rectange, either a Rect object or parameters of a rect. Then a string is your text. Align can be omitted as defaults to left align (0). You only need to specify align if you want it centered (1) or right aligned (2) in the rect you specify.

Is that the coding to draw text or for how the text is actually drawn in the Bitmap class?
I need the coding for how its drawn.

What?

He wants the hidden Bitmap class so he can see the actual code for the draw_text method.

That's what I thought right after I took off.

I am sure it uses some sort of API, as it reads font files, etc.

I definitely found the code for bitmap somewhere on the web, because I know people have definitely modified and extended it's methods. I just can't remember for the life of me where.

You can extend and modify methods without knowing the original code.

class Bitmap
  alias draw_shadow draw_text
  def draw_text(x, y, w, h, string, align = 0, shadow = false)
    if shadow
      col = self.font.color.clone
      self.font.color = Color.new(0, 0, 0)
      draw_shadow(x + 1, y + 1, w, h, string, align)
      self.font.color = col
    end
    draw_shadow(x, y, w, h, string, align)
  end
end

There, extended the method to draw shadows. I definitely don't know the original code

Theres something I found. I am sure they use something like that, as the parameters and such looking strikingly familiar...

 

[syvkal]

Ah thanks, that actually helps a bit.
Just one question to Prexus, or anyone.
You know the x, y, w, h and all that? What are used in the draw_text command?
Is it draw_text(x, y, w, h, string, align = 0)
Or is it draw_text(rect, string)?

It's draw_text(*args)

*args lets any amount of arguements be given, you then process them in the method.

def draw_text(*args)
  if args[0].is_a?(Rect)
    draw_shadow(args[0].x, args[0].y, args[0].width, args[0].height, args[1], args[2])
  elsif args[0].is_a?(Integer)
    draw_shadow(args[0], args[1], args[2], args[3], args[4], args[5])
  end
end

It didn't work...

I changed draw_shadow aswell, coz thats not a real code, but it still didn't help.
Got any other ideas?

If not this can be left as a failed attempt lol
