Padding/margin in paragraphs

[esti]

Hello!

Sorry for my newbie question but, how can I add margin or padding in a
paragraph? I've tried this:

<pre>
answers.each_with_index do |answer, i|
pdf.bounding_box [100, 100], :width => 200 do
pdf.text "Answer + i.to_s + ":" + answer
end
end
</pre>

... but all the answers are placed in the same absolute position and
overlap with each other.

The only place in the API where I've found something related to
padding is in tables. Do I have to make a table for this?

Thank in advance!

Your loop is *outside* the bounding box, re-setting the top left
corner each time.

try:

pdf.bounding_box [100,100], :width => 200 do
answers.each_with_index do |answers,i|
pdf.text "Answer + i.to_s" + i.to_s + ":" + answers
end
end

To put padding between the text, check out pad(), pad_bottom(),
pad_top(), and move_down()

Hi Gregory!

I'm still not getting what I need. I tried what you said but now I'm
getting each answer in a different page, in (100, 100) position. What
I want is different paragraphs in the same page, with some blank space
on the left.

I knew about pad() functions but I want to add the padding to the
left, which is not possible with any of them.

The output that I want, is something like this (notice blank spaces in
the left):

Question: Is this a question?
Answers:
Answer 1: Yes it is
Answer 2: No it isn't

Any ideas?

If that's what you're getting, your code is actually more complicated
than the examples you've shared.

I'm not sure that you're intentionally putting your text at the bottom
of the page. Y=0 is at the bottom margin in Prawn. (Or the bottom of
any bounding box you create)

require "rubygems"
require "prawn"

pdf = Prawn::Document.new
answers = ["Yes it is", "No it isn't"]
pdf.bounding_box [100,pdf.bounds.top-100], :width => 200 do
answers.each_with_index do |answer,i|
pdf.text "Answer #{i}: #{answer}"
end
end
pdf.render_file "foo.pdf"

Hi Gregory!

Your example works exactly as I need, but I somehow can't get it to
work in my code. I'm travelling this week and don't have much time to
take a careful look, I'll get back to this next week.

Thanks a lot for your help!

Hi again!

As I said, I can't get this to work. I think the problem is that I
have text before and after this block. Can you please have a look at
this example?

require "rubygems"
require "prawn"

pdf = Prawn::Document.new
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"

answers = ["Yes it is", "No it isn't"]

pdf.bounding_box [100,pdf.bounds.top-10], :width => 200 do

answers.each_with_index do |answer,i|
pdf.text "Answer #{i}: #{answer}"
end
end

pdf.text "More stuff"
pdf.render_file "foo.pdf"

I would expect "Some stuff" lines to go first, then "Answers" below,
and then "More stuff" below, but I see everything cluttered up.

Anybody?

[Gregory Brown]

If you place the bounding box 10 points from the top of your page (as
you are here, look at the top-left corner of the box), why would you
expect this?

I think what you want is:

pdf.bounding_box [100, pdf.y - pdf.bounds.absolute_bottom], ...

Hey!

Forget my last post, I found the solution in this other thread!
http://groups.google.com/group/prawn-ruby/browse_thread/thread/cc0930099ff4c4aa?hl=en

So, what I needed was to replace "pdf.bounds.top-10" with "pdf.y -
pdf.bounds.absolute_bottom". Here is the whole script in case it is
useful for somebody else.

require "rubygems"
require "prawn"

pdf = Prawn::Document.new
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"
pdf.text "Some stuff"

answers = ["Yes it is", "No it isn't"]

pdf.bounding_box [100,pdf.y - pdf.bounds.absolute_bottom], :width =>

200 do
answers.each_with_index do |answer,i|
pdf.text "Answer #{i}: #{answer}"
end
end
pdf.text "More stuff"
pdf.render_file "foo.pdf"

Thank a lot for the help!
