[Postscript] Emitting Postscript from REBOL

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

[1015x2]
I guess so.
But they print fine to the printer.
Henrik

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

[1023]
Yeah .. seems to work.

sizes?
Graham

I have text centring and flow across multiple pages
Henrik

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

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

I haven't seen it. Synapse?
Graham

hang on .. let me see.

from "hokey" to "good looking"
Graham

Looks good to me.
Henrik

but it takes 2 seconds to render

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

how is barcode part done?
Rebolek

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

[1037x3]
rebolek: it's my own. it uses LIST-VIEW and sports autocompleting

sounds great, are you going to release it? because IIRC VID' drop-down 
is somehow buggy
Graham

a large chunk of text flows thru three textboxes and over into the 
next page.
the text is also partially justified ...
Henrik

rebolek: this is a prototype and code is somewhat messy, but I want 
to make a better version of it for release. it depends on a few custom 
and ugly things that I don't want to release. it works quite well, 
has keyboard navigation and everything.

Graham: Why is the text visible only on 50% and 100% zoom?
Graham

[1046x5]
It's visible at all zoom for me.
I think you don't have the right fonts installed.
You need to install this set of fonts ...

these are the TT equivalents of the standard PS fonts

OK, I'll try that, thanks
