[Postscript] Emitting Postscript from REBOL

Geomol

[990x2]
www.rebol.com opened OK in NeoOffice, and I could change to "Print 
Layout". Right-margin is not perfect (as often with HTML, because 
it isn't a wysiwyg format), and it can probably be configured. Saving 
as PDF gave me exactly what was seen on the screen.
Volker, so my first impression is, that OO is OK to handle HTML, 
but not perfect (and how could any program be with all that misunderstanding 
of HTML out there).

H: I think there is hyphenation in CSS 3, iirc.

Some small progress .. I can now get floating text tables, and text 
that flows from one textbox on one page to the next page.  But not 
completely error free yet :(
This is in Draw .. haven't tackled this in PostScript yet.

do http://www.compkarori.com/reb/psd2draw5.r
this is an alpha dialect that just does draw at present.
I have two textboxes on the first page, and one on the second.  Text 
flows from the first page to the second, sort of justified.
A textbox is used also to centre the large titles on each page.
I have no idea why the small text looks as though it is in bold.
the point of having this dialect is to create page templates for 
viewing data from databases or whatever.  The text is replaced either 
by evaluation or by compose, and you have your draw layout.
sure you can create VID layouts for viewing data from databases, 
but you can't print it easily.
Need to generate bar codes in postscript ?  Here's some software 
on a MIT/X-Consortium license http://www.terryburton.co.uk/barcodewriter/
so, as the author says, you can include a barcode as simply as
50 450 moveto (1-86074-271) (includetext) isbn barcode

I know about ez-plot being capable of doing very useful plots ( barring 
sequential date data ).
but of course, there's no great way of printing out these plots.
This is a simple graph ( multivariable ) graph using the postscript 
dialect.  http://www.compkarori.com/emr/graph.png
That's how it looks in draw and also when printed to a postscript 
printer.
It would be nice to have vertically oriented text for the y-axis 
label .. but I'm going to have to think again about text rotation 
in draw so that it can be mapped easily also to postscript.

is that graph drawn with AGG?
Graham

Draw is AGG is it not?
that graph is output from my EMR program.

the fonts look a little smeared.
is that because they are vectorized?
Graham

I guess so.
But they print fine to the printer.

that's good
I haven't followed it, but did you solve font positioning in DRAW 
vs. postscript?

dunno what kind of graphs you are using, but sequential data, maybe 
mrtg or rrdtool would be usefull? Of course it would not probably 
solve your problem with printing ... what you have apparently works 
for you ...

I don't have a problem with font positioning in draw and postscript.
Just text rotations and other fancy stuff.

what about centering?
Graham

Yeah .. seems to work.

I have text centring and flow across multiple pages

maybe it's time for me to test it...

Didn't I upload an example of text boxes and flow and centering?

I haven't seen it. Synapse?

Looks good to me.

it does not look like "hokey" to me :-)

it's plain VID, done in double size, blurred a couple of times and 
some contrast added to it and then scaled down quickly with 'fit

Henrik, this drop-down menu is your own or standard VID?

rebolek: it's my own. it uses LIST-VIEW and sports autocompleting
