How to achieve this, like a horiz. align to center?
I`m trying Prawn to generate PDFs, but having a problem to place a
short text (3 words) at the horiz. middle of the page. This code
places the text 2 or 3 centimeters right from the middle.
Prawn::Document.generate('public/' + dir +
"certificado.pdf", :page_size => "A4", :page_layout => :landscape) do
bounding_box([0,430], :width => 800, :height => 600) do
text nome, :size => 28, :align => :center
end
end
As I change ":width => 800" value, the distance from the middle
changes. I tried to remove width and heigth options, hoping the
bounding_box to fit all the page, but I got a error.
Sorry for responding to a very ancient post, I almost never read the
Rails list...

Get rid of the bounding box entirely and just do: text nome, :size =>
28, :align => :center
You were centering your text within the box, not within the page.

Please re-subscribe. You probably missed the "Are you human" form
field, which caused you to be denied.
Hello Greg!
at first, congratulations! very nice work!
funny, today a tried again to subscribe to the prawn group
and noted the "r u a human?" question. So I subscribed and returned
here,
in the rails talk, to copy my msg to there, then I saw you reply
well, here we go...

in really I tried this before, but got a different bad aligment
problem.
Also, I`m using bounding box to position my text. Is there another way
to position text without bounding box?
Moreover, if I keep using the bounding box, how to position it at
exact
center of the page?
PS: when we close this thread, I will copy it digested to the prawn
list.
I had to use bounding box to position the text.
The trick is to use the bounding_box parameters:
:width => bounds.width, :height => bounds.height
instead
:width => 800, :height => 600
now prawn center the text exactly.
See all the code...
Prawn::Document.generate("Certificado.pdf", :page_size =>
"A4", :page_layout => :landscape) do
bounding_box([0,430], :width => bounds.width, :height =>
bounds.height) do
text name, :size => 28, :align => :center
end
bounding_box([0,180], :width => bounds.width, :height =>
bounds.height) do
text "#{local}, #{date}", :size => 20, :align => :center
end
end
