I'm pretty sure they're supposed to be equivalent.

IIRC when I was trying to match linux fonts to windows... arial and 
helvetica where pretty different when applied over each other...

Sigh .. looks like I need a better way to map postscript points to 
the draw coordinate system.

Gabriele .. any hints?

would it be possible to use caret-to-offset?

I need some fudge factor .. at present I am off by a little high 
and to the right.

I am previewing my draw doc, and when I generate the ps file, the 
coordinates are to the north-east in the ps file.

could it be an aspect ratio problem?

or is the offset constant all over the drawing area?

so presumably I have to reduce them a little in the south-west direction

I'm not sure.  I guess I should try a scientific method of determing 
this.

ie. draw a grid and see what happens

at present, I am keeping the x as is, and just reducing the y by 
the size of the page

so an a4 page which is 595x842 points, 0x0 becomes 0x842

This Rops viewer is very demanding .. doesn't like the postscript 
I am emitting, but ps2pdf works fine :(

Agghh.. maybe the mapping is okay after all!

Using my "postscript" draw viewer at 83%, it looks almost exactly 
the same as the RoPS viewer at 60%.  So, the mapping is pretty accurate. 
 I was being fooled by the acrobate conversion which is not so accurate.

try this out ...

do http://www.compkarori.com/reb/psd2draw.r

when you click on the "print" button, it generates a test.ps file 
which is the postscript "equivalent" of the stuff on screen ... except 
for the rotated objects

which are not placed correctly.

I map the standard postscript fonts to the free GNU postscript equivalents 
in that zip file I mentioned.

true type equivalents ie.

ok

I am a little confused about some of these ps fonts - sometime it's 
called BoldItalic, and other times it's called BoldOblique

but this is basically what I need to do

It looks doable to me.

You don't actually have to change to using my dialect.

You can create the barcode in John's as an eps image, and insert 
it into the postscript.

I presume you don't really need to preview the barcode.

an eps file is just a postscript file which obeys certain conventions.

Anyways, I quite chuffed to get this preview and printing to postscript 
working ... after years of no way of printing from Rebol.

got a bit of a makeshift preview now. maybe I'll use it for the next 
version for the other races I'm doing this for

So, you got mine working??

nope, I made a little layout that works like a preview

hand-made but it's enough

for now... later on I will be needing to create a real preview, so 
I'll be looking into it

to get the ps dialect matching the draw dialect, I need to make the 
text obey cr/lfs.

fortunately I don't think I need that

That's pretty good work Graham ! Well done guys.

OT: How to Spot Arial -- http://www.ms-studio.com/articlesarialsid.html

This is one of the main things that makes Arial look like Helvetica 
at first glance, even though the details are different.

At work today, and got a chance to try out the postscript printers. 
 It's amazing .. I can print from my draw preview to either the network 
colour postscript printer, or to the old HP Laserjet 4MP on the lpt1:

and with ridiculously little code

I'm wondering now whether the tendency for new printers to have built 
in postscript is going up or down...

I remember that NeXT printers were so cheap because all the postscript 
processing was done by the NeXt OS, and so the printer was just a 
bare engine.

A bit like Windows printers I guess.

If you don't have a postscript printer .. I recall in the old days 
you created a large bitmap in memory, and then printed it all out 
dot by dot.

I remember driving my dot matrix printer like that.
