[Postscript] Emitting Postscript from REBOL

that's right. the font points are of a smaller dpi than the coordinate 
system it seems

I'll submit a rambo ...

I think the font size is bound to the screen resolution
under linux they tend to go up or down, because you can set the DPI 
settings in X
Graham

So, what do you suggest?
Henrik

post a RAMBO and see what happens. at least on the size difference 
between fonts in VID and fonts in DRAW
Graham

Perhaps you can ..

I can't confirm it, and I haven't worked that much with it yet to 
be certain.

Posted a rambo on the subject.
I can't see RT changing anything here without invalidating every 
script before that uses a
font.

it'll have to be worked around for now. if the size deviation is 
proportional to the size of the font, it could be fixed with a coefficient 
on the font size of the DRAW text

Chris posted this to me
Is this indicative of the current problem?

>> foreach typeface ["arial" "times new roman" "verdana" "trebuchet 
ms"][

[    layout [tx: text font [name: typeface size: 10] do [probe second 
size-text tx]]

hmm... preview.app has a funny way of detecting when to rotate the 
paper. if the first given text is rotated 90 degrees, it will rotate 
the paper, otherwise it will not. I wonder if this is standard behaviour?
oh, great, now I can't print Danish letters with PS

Starting to hit the inticancies of the postscript language?

geomol, seems postscript.r needs to be patched to convert the chars 
to octals to print them out
jaime, just need to figure out how to do it
(under a bit of time pressure)
geomol: http://www.sslug.dk/emailarkiv/prog/2002_09/msg00132.html
<--- this might be interesting
geomol, actually the entire thread is interesting
by inserting the code in postscript.r I can get the chars I want. 
works fine now, but you need to specify the fonts correctly from 
"HelveticaBold" to "HelveticaBold-ISOLatin1" instead.
(the code mentioned in the link)

Ok, I'll take a look...

geomol, I can upload what I did

Seems a bit complicated to get ISO-8859-1. What about other languages?
Henrik

I don't know. strangely, I didn't need them :-)
I tried representing the chars with octals, but that didn't work. 
I don't know what I did wrong, but it would be a simpler solution

pdf does not support unicode fonts, and i guess the same might be 
true for ps... so good luck :)
Henrik

is anyone working on higher level stuff for postscript.r? I'm going 
to work on a table generator
Graham

I'm semi-wondering about implementing text that flows from page to 
page with full justification.
Henrik

about DRAW, I'm sure how fit it is for this yet. I had serious problems 
with it under Linux today (misalignment and crashes too)
Graham

well, if you have crashes, you need to report them.
Did I mention that I have three columns of text snaking up and down 
an A4 page?

if I could test it... wasn't on my machine and I couldn't get console 
output
that sounds interesting?
Graham

that was your runner labeling application?

the centering algorithm I wrote didn't work under Linux either
because of the stupid differences in font sizes
Graham

Hang on.
Henrik

yes, I rewrote the preview to be done with VID. I lost anti alias, 
but gained proper centering
Graham

What you should be doing is writing a preview in draw, but have a 
postscript routine that does centering for you.
That would work.
Henrik
22-Apr-2006
[829x3]
yes it would
I suppose I should modify postscript.r some more
it would also be needed for proper paragraphs in tables
Graham

My aim is to get perfect postscript output .. and at least a rough 
approximation in draw.
Henrik
22-Apr-2006
[833]
yes, at least in a clear way to make sure that the postscript is 
like it should be: that centered output really is centered, font 
size is completely accurate and such

I would have continued to use pdf-maker except there's no easy way 
to flow text like this.
