World: r3wp

but let's start with a postscript dialect and then see if we can 
retrofit draw to it.

that way we are not constrained by draw.

Then I just need a list of PS commands to get started on the dialect.

since rebol3 is coming, and View may well change, it makes less sense 
to stick to the past.

this has a reference at the end : http://www.cs.indiana.edu/docproject/programming/postscript/postscript.html

Is this works, you can then render your paint images to postscript 
printers :)

Is it the "Index of Operators" in the link, you gave?

yes.

add, arc, ...translate

yes.

pen red
            line 30x30 50x20 70x70 40x50

newpath
	1 0 0 setrgbcolor
	30 30 moveto
	50 20 lineto
	70 70 lineto
	40 50 lineto
	stroke

pen blue
            box 20x20 80x80

newpath
	0 0 1 setrgbcolor
	20 20 moveto
	60 0 rlineto
	0 60 rlineto
	-60 0 rlineto
	closepath stroke

that's sort of equivalent in my understanding

PostScript dialect test ready. Try this:
do http://home.tiscali.dk/postscript/postscript.r
s: postscript [font ["Times-Roman" 20] ["Hello World!"]]


s is now the PostScript output, that can be saved to a PS-file or 
sent to a printer.

I've got 404 :(

is that url correct?

no :) 2 seconds

do http://home.tiscali.dk/john.niclasen/postscript/postscript.r

Sorry about that.

Local cache?

less haste less waste ! :)

no,it's a 404 response.

same here

It worked for me just before, now it doesn't!?? Weird, I get same 
error now.

I'll check with ftp ...

Strange, I can see the script on the server with ftp, but I can't 
reach it with browser or rebol.

Any ideas?

must be a case problem.

works here ok, must be a connection problem

yes, try now

now it works

Now it works. It seems, it take a little time, before tiscali makes 
content reachable.

Ok, looks okay.  But each element needs to be placed on the page.

?

you need to tell the postscript engine where to place the text.

eg. 72 72 moveto

which is one inch from the left bottom edge

It's a start.
What happen, if you leave out that part?

nothing happens I suspect.

there's also a postscript preamble or header.

%!PS-Adobe-3.0
%%Creator: Synapse-EMR 3.01
%%LanguageLevel: 2

Oh, misunderstood.
Try:
s: postscript [font ["Times-Roman" 20] [at 72x72 "Hello World!"]]

You can position with AT pair!

Now the dialect has to be defined precisely with all the functionality, 
we want.

gsave
 .75 setgray
 /Helvetica-Bold findfont 72 scalefont setfont
 72 100 moveto
 (Hello World!)	 show
 grestore

I would save the state and then restore it.

I need to learn more about PostScript.
