When setcm is used, max coords is 20 or so to be within page.

21x24

no it stops parsing when the word 'setcm is reached

I have not been watching this very close, so to get me up to speed....you 
are writing an emitter from Rebol to PS?

Reichart, yes.

(OSX converts it to PDF)

Cool.

it's also really small

just a basic one with text and some graphics.

how about pulling a "NeXT" and making a PS VID? : )

hehe

Gabriele is writing a PDF emitter for MakeDoc and QML.

reichart, shush! Steve Jobs might be reading this.

: )

150 lines of code so far. Can be seen here: http://home.tiscali.dk/john.niclasen/postscript/postscript.r

I think Sun also made a PS window manager

Yeah, I was reading the code as I posted.

Very cool.

it's primarily to make more methods for graphical printing with rebol

Postscript is copyrighted?

I hope not?

oops, don't spoil the fun! ;-)

Reichart, maybe you can find out? You know where to look.

http://www.pugo.org/pyps/<--- don't tell this guy that

if it was, why would Adobe put the entire specs online?

Adobe gives permission to anyone to:
Write drivers to generate output 
consisting of PostScript language commands.
It's from the ref manual.

John, cool. Henrik.....putting thier spec online would not have led 
me to beleive it was free of copyright.  But I wanted to confirm.

We need to include an appropriate copyright notice.

I have a cool idea for PS with our Qwikis then.

It's in section 1.4 in the ref manual.

geomol, and BSD license

I managed to switch y-axis, try:
do http://home.tiscali.dk/john.niclasen/postscript/postscript.r

write %test.ps postscript [page [switchy setcm linewidth 0.1 path 
[setgray 0.8 line 1x1 5x5]]]

If setcm is used, then switchy has to come first.

It seems like, it isn't aligned right though.

Needs to be moved up.

Well, that's it for today. Good night!

that's it for me too... night

Henrik, are you going to develope your ean13.r any further so that 
everything is there and saves to a file?

Hey, cool PostScript pic, Henrik! :-)

mapping colours from rebol to postscript.

0 0 0 => black 0.0.0
1 1 1 => white 255.255.255

view-ps-color: func [ color [tuple!]][ return reduce [ color/1 / 
255 color/2 / 255 color/3 / 255 ]]

don't know how a ps engine will cope with this

>> view-ps-color orange
== [1 0.588235294117647 3.92156862745098E-2]

seems to have no problems with this format.

Thanks!

New version! PostScript is default set to DeviceGray with no colours. 
To set it to DeviceRGB, I made a command in the dialect for that. 
Try:
do http://home.tiscali.dk/john.niclasen/postscript/postscript.r

write %test.ps postscript [DeviceRGB page [switchy linewidth 5 path 
[setcolor 255.0.0 line 50x50 50x100 setcolor 0.255.0 line 50x100 
100x100 setcolor 0.0.255 line 100x100 100x50 setcolor 255.0.255 line 
100x50 50x50]]]

Another example:

write %test.ps postscript [page [font [Times-Roman 40] linewidth 
0 path [at 72x720 "REBOL PostScript Dialect"] path [line 72x716 520x716] 
font [Times-Roman 16] path [at 96x680 "With this dialect it's possible 
to easily produce PostScript output."] font [Helvetica-Oblique 12] 
[at 72x72 "PostScript is copyright Adobe."]]]
