sorry, subset of postscript

btw. on the compression issue, is it possible to decompress pdf streams 
inside rebol if they are properly massaged? I thought of building 
template pdf files, where you could search/replace the text inside 
those streams to make new pdfs

henrik, ps is definitely easier to emit. too bad windows has no support 
for it out of the box.

interesting

I've always wanted to build a postscript emitter for REBOL. This 
would solve many problems in the printing area.

it would be cool if you could take a DRAW block and convert that 
to postscript

that shouldn't be hard. actually, being that ps is forth, once you 
code the functions you need it's almost a 1:1 translation

(gradients may be the hard part)

well, if lines, curves, text and general paper size handling could 
be done first, that would be a very good thing

text is a different issue, you need to do the typesetting yourself, 
and you eventually need to handle fonts.

Gabriele, just tried out pdf-maker for the first time yesterday. 
Very nice and quite useful.

for the typesetter, the one i'm designing for pdf maker 2 could be 
easily reused (based on TeX, and i will write it as a RLP so you'll 
have full docs)

james, i'm glad it's useful :)

it is indeed very useful

but it would be even more useful if we could emit postscript directly 
from code.

would you mind if I made a group that would focus on the challenges 
in such an effort?

I have to design a complex form with lots of boxes and text. Is there 
a dialect to define that ? thxs

Gabriele, will you have a pdf-maker 2 alpha ?

Joe: I have no ETA yet.

btw, I just fixed a bug with the View 1.3 version of the pdf-maker 
and images.

thanks. Gabriele, you specify A4 with as 211mm but it is 210mm http://www.cl.cam.ac.uk/~mgk25/iso-paper.html

i got the number somewhere - i don't remember where, though. maybe 
they where converting back from inches and so had an error?

The reason for magic numbers must be written down, even if it's just 
; I'm not sure about this number

The reason is in the document of which Joe gave the URL two messages 
ago. It's all to do with the square root of 2.

tolerance seems to be +/- 2mm, so 211 is still acceptable. i'll fix 
it in the future though.

I just printed a PDF doc and it shows 3 different measures: 1) the 
preview window shows 210,02 x 297,01 2) Document: 211,0 x296,7 and 
3) Paper: 209,9x296,7 Weird!

So maybe PDF uses 211 for the doc but assumes the paper is 210 ?

Why I am getting this error?

hmm, anything unusual in your user.r file?

also, what version of REBOL?

any reason why you are using 1.3.50? also, that winpath-to-file shows 
you do have something in user.r ;) anything you may be accidentally 
overwriting? (btw, rebol has TO-REBOL-FILE as native, so no reason 
to define your own)

There was a reason - already forgot it.

The only thing in user.r was the function above (except set-net) 
- and I removed it ;-)

Could it be connected with that I am starting rebol with view.exe 
-i ?

perhaps your version of pdf-maker.r is corrupted?

Janeks, the only reason to use 1.3.50 is if you have rebcode that 
hasn't been converted to the new naming convention.

seems very strange to me, the pdf maker should not worry about -i 
(doesn't touch view-root etc.)

as graham suggests, try redownloading it just to be sure.

it's also possible that the 2-jun-2006 version has a bug; it was 
released to fix a bug with images, and it's not to exclude that it 
introduced another bug, although i haven't got any reports about 
it.

ah, confirmed it was a bug. i just fixed it and uploaded a new version.

Everyone using the PDF Maker on View 1.3 should update to this version, 
as previous ones contained bugs.

if you are using it on 1.2, please continue using the old version 
(from 2003 or so).

What about unicode in pdf?

my plan is to eventually have that in version 2 (a first release 
of version 2 is due in a couple weeks). however, note that while 
the pdf format directly supports latin1 encoding, it does not support 
unicode encodings directly. so it's a pain to make it work. openoffice, 
for example, creates divides the characters you use in the document 
in groups of 256, then creates a new custom font for each group. 
(i also assume that the 14 standard fonts do not support unicode, 
so you need custom font support to be able to use unicode.)

please blame adobe for this. :)

Are you able to give us a preview of the capabilities of version 
2?

Will things like footers, and page numbering be there?  Automatic 
text flow?

I would want those things as a layer above pdf maker

eventually version 2 will do whatever TeX can do minus math.

I already have the total-fit line breaking algorithm working (in 
the basic version).
