Default gfx.drawstr flags???

Having difficulty figuring out these 'flags'.

Here's the official documentation:



Lua: gfx.drawstr("str"[,flags,right,bottom])

Draws a string at gfx.x, gfx.y, and updates gfx.x/gfx.y so that subsequent draws will occur in a similar place.

If flags, right ,bottom passed in:
  • flags&1: center horizontally
  • flags&2: right justify
  • flags&4: center vertically
  • flags&8: bottom justify
  • flags&256: ignore right/bottom, otherwise text is clipped to (gfx.x, gfx.y, right, bottom)



I want to center justify, w/o doing it manually...

I've tried a handful of different combinations of inputs into the function, without avail.

flags=1 centers the text between gfx.y and gfx.drawstr's right parameter. The bottom parameter must also be set for it to take effect.

Code:

local CENTER_H = 1
local CENTER_V = 4

function loop()
  gfx.x = 0
  gfx.drawstr("Hello World!", CENTER_H | CENTER_V, gfx.w, gfx.h)

  if gfx.getchar() >= 0 then
    reaper.defer(loop)
  end
end

gfx.init("", 400, 100)
gfx.setfont(1, "sans-serif", 24)
gfx.r, gfx.g, gfx.b = 1, 1, 1
loop()

Thank you!

Sorry about the small mess I made trying to upload my project map to ReaTeam, I think my error was that I messed up the formatting for the 'documentation' segment of the Upload Tool..

Is there a way I can specifically name my script using the Upload Tool, in its entirety?

flags=0 seems to be left-justify (and clip to right/bottom):
