text rotation in VTK different from vcs way

[doutriaux1]

If I "left justify" a text, and then rotate it, the "justify" seems to be applied to the rotated text.
Trying to show this here, I have a vertical centered and left justified text.

First putting 3 points on the same "y" location I would expect (with the letter rotated 90 degrees)

A     A
B     B
C  A  C
D  B  D

But in fact I get

A     A
B  A  B
C  B  C
D     D

Actually it seems that pdf outputs correctly but screen and png are not.

Ok pdf (converted to png) gives:

@dlonie I think you're the right person to fix this, let me know if you need more details about it.

@doutriaux1 Hmmm, that shouldn't be happening. I'll look into it.

What test produces that image for testing?

[doutriaux1]

let me try to make a quick test for you
also it appears that png and pdf do not behave the same in that regard

here is a sample code with the "old" (1.5.1) output

import vcs

x=vcs.init()
#Plot a rectangle to show the bug issue
r=x.createfillarea()
r.x=[.25,.75,.75,.25]
r.y=[.25,.25,.75,.75]
r.color=242 # red?
x.plot(r)



# text rtated in middle/bottom
for i,valign in enumerate(["top","half","bottom"]):
  for j,halign in enumerate(["right","center","left"]):
    t=x.createtext()
    t.x=[.25*(1+i)]
    t.y=[.25*(1+j)]
    t.angle=90
    t.valign = valign
    t.halign= halign
    t.string=["%s-%s" % (valign,halign)]
    x.plot(t)

x.png("texts")
x.pdf("texts")
x.postscript("texts")
