World: r3wp

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.

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)

So, port TeX to Rebol ?

Neat :)

and of course i plan to document it very well (again, as good as 
TeX) so that everyone will be able to use it

How's your literate tool coming along?

only problem is that this will take time so i'm not sure i can give 
an eta. however, qtask needs pdf output so this should happen soon 
enough.

I guess closures will help in programming some like TeX.

i haven't worked on wetan much in the last weeks. busy with other 
things. but i need it so i hope to be back to it soon.

Tracking all those margins , current text positions, translations, 
rotations etc.

so will rebol 3 be able to count presice metrics for fonts etc.?

surely that's not part of Rebol 3.

It would have to be an add on product.

hmm, r3 will have rich text, but i don't think there are any plans 
for a real typesetter.

what's this new typeset! function then :)

just kidding ...

:-)

;)

once you have a typesetter written in rebol, though, you can apply 
it to draw too; draw doesn't offer the low level access to font data 
you need, so that will need to be separate; but if you can do it 
for pdf, you can do it for whatever, if you use the same fonts.

So, that also mean creating bitmaps for direct printing?

well.... i guess to image! can help with that.

unless you want to rewrite AGG in rebol ;)
