Hi,
I idea is to implement a scrolling text using the IncrementalTextLayout.
In some cases, I need this scrolled text 90 degrees rotated.
Therefore I have apply a rotate and a transformation before I call the draw
method of the text layout.
The problem seems to be that one a rotation is in effect the result is not
is I would have expected it.
Especially the meaning of the width and heiht properties of the
IncrementalTextLayout is really strange.
I have attached a short example where I try to show what i mean (width the
scrolling)...
Does anybody know how I can achieve a scrolled text rotated by 90 degrees?
Thanks in advance,
Martin
