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

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

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)

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?

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

Hang on.

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

What you should be doing is writing a preview in draw, but have a 
postscript routine that does centering for you.

That would work.

yes it would

I suppose I should modify postscript.r some more

it would also be needed for proper paragraphs in tables

My aim is to get perfect postscript output .. and at least a rough 
approximation in draw.

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.

And with postscript, you can create your own fonts

I just think PDF Maker is a bit too hard to build layouts in

if the ones you need are not supported.

yes that's a problem. I will need OCR fonts at some point

Has anyone looked at the image format for postscript?

How easy would it be to convert rebol's image format to that needed 
for postscript?

haven't looked at it. some people say that it's "tricky"

I presume it is similar to the way images are handled in pdf ...

possibly, but it doesn't work properly in PDF Maker

Oh ?

I've created pdfs with jpegs .. and they seemed to be okay.

I've tried without luck. that's why I started doing barcodes as vectors

http://www.compkarori.com/images/test.pdf

is a page I created in pdf-maker a few years ago.

the image is not correctly apportioned but that was beacause I was 
lazy.

the script was written in 2002.

pretty neat looking

but maybe it was because it was an external bitmap and not one created 
by rebol

the image there was loaded off a camera

newlines are made with \

that should be easy to do...

Looking at algorithms for text justification.  One I looked at says, 
collect all the words that will fit on a line with a space, count 
the spaces, and the area left over, and allocated part of that extra 
space to all of those spaces.

No kerning involved in this one.

Text flow, with justification, word wrapping, and footnotes is not 
a simple task.

Since your centering routine didn't work, I just stuck with my original 
one, and that seems to work for me.

I've got a box with text in it, and all the text is centred.  I can 
translate that box to anywhere on the screen.

is that in DRAW?

Yes.

and postscript.

Hmm.  Lengths of text strings is different when measured as one string 
including spaces, or adding the lengths together of each word with 
a space in a sentence.
