My aim is to get perfect postscript output .. and at least a rough 
approximation in draw.

yes, at least in a clear way to make sure that the postscript is 
like it should be: that centered output really is centered, font 
size is completely accurate and such

I would have continued to use pdf-maker except there's no easy way 
to flow text like this.

And with postscript, you can create your own fonts

I just think PDF Maker is a bit too hard to build layouts in

if the ones you need are not supported.

yes that's a problem. I will need OCR fonts at some point

Has anyone looked at the image format for postscript?

How easy would it be to convert rebol's image format to that needed 
for postscript?

haven't looked at it. some people say that it's "tricky"

I presume it is similar to the way images are handled in pdf ...

possibly, but it doesn't work properly in PDF Maker

Oh ?

I've created pdfs with jpegs .. and they seemed to be okay.

I've tried without luck. that's why I started doing barcodes as vectors

http://www.compkarori.com/images/test.pdf

is a page I created in pdf-maker a few years ago.

the image is not correctly apportioned but that was beacause I was 
lazy.

the script was written in 2002.

pretty neat looking

but maybe it was because it was an external bitmap and not one created 
by rebol

the image there was loaded off a camera

newlines are made with \

that should be easy to do...

Looking at algorithms for text justification.  One I looked at says, 
collect all the words that will fit on a line with a space, count 
the spaces, and the area left over, and allocated part of that extra 
space to all of those spaces.

No kerning involved in this one.

Text flow, with justification, word wrapping, and footnotes is not 
a simple task.

Since your centering routine didn't work, I just stuck with my original 
one, and that seems to work for me.

I've got a box with text in it, and all the text is centred.  I can 
translate that box to anywhere on the screen.

is that in DRAW?

Yes.

and postscript.

Hmm.  Lengths of text strings is different when measured as one string 
including spaces, or adding the lengths together of each word with 
a space in a sentence.

Text flow, with justification, word wrapping, and footnotes is not 
a simple task.
 you bet :) that's 60% of TeX.

... the smiley was not grin, I just tried to produce valid rebol 
line :-) .... insisting we are able to read archives in 3.0 :-)

Without re-writing TeX, what I am trying to do is allow text to flow 
from one text box to another on the same page, and then on to other 
pages.

Although this is not too bad to do if you know in advance how much 
text there is, it's somewhat harder when you don't.

Is a "fudged" example of page with two textboxes where the text flows 
down one textbox and then into the other while nearly being justified.

If you use the "edit data" button, and change the word "justify" 
to "left", and save, the text reappears without the full justification.

As you can see, the justification algorithm is imperfect .. and it's 
still a little ragged on the right.

I guess it doesn't matter too much as it is just a preview for postscript. 
 the output to postscript is yet to be done.

All this stuff is harder than I first thought.  I now have to implement 
floating text tables so that one follows the other when the text 
amount is unknown.

so maybe you now have an idea why i haven't done pdf maker 2 yet. 
:)

Hey, Gabriele .. you're forgiven !!

Have you got some ideas on reading the TeX sources ?

i have studied TeX a lot in the last couple months.

my plan is to be as good as TeX in pdf maker 2 (no math formatting 
planned though)
