  Correct.

Not in official POV, but there are h_align_center and v_align_center
keywords in MegaPOV.

  Aren't they kind of obsolete? It isn't much more difficult to do the
same with the extents functions.

The extents functions were there first, but the MegaPOV text alignment
options keep getting reinvented. Over time MegaPOV has had "position 2"
and "align_center" syntax for text centring as well as the current
"h_align_center"/"v_align_center" syntax. I guess some people feel that
there's a need for it.

Try this:

#local txtL=text { ttf FontName, "A",1,0 }

object { txtL
   translate -(min_extent(txtL)+max_extent(txtL))/2
}

Are these special text functions still in MegaPOV 1.2.1, I didn't know.
Thanks for the advice!

They're in 1.2, I've not checked 1.2.1 but it's very unlikely that
functions would get deleted from a minor level change.

looks good, my code is a little dirtier:

----code
#macro WoodBlock(Letter, BlockColor)
 #declare LetObj = text {
  ttf "AdLibRg_.ttf", Letter, .2, 0
  rotate 90*y
  scale 1.5
  texture {
   pigment { BlockColor }
   finish { phong 1 }
   normal { Norm_W }
  }
 }
 #declare Center = max_extent(LetObj)-min_extent(LetObj);

 difference {
  object {
   IW_Plank_RoundW(18, 2, 2, 2, 4, 2, 0.1, 0.004, P_CM_IW_01, Fin_W, Norm_W,
1)
   translate -z-y
  }
  object {
   LetObj
   translate <-max_extent(LetObj).x , -Center.y , Center.z>/2
  }
 }
#end
----code

I used Christoph's IsoWood macros btw
