so I think there should be an option to leave that out, or by default 
not have it. I'm guessing most people want to generate and print 
PS file, rather than read and edit them by hand.

ok, the inserting of the newlines is the problem?

didn't try that with /update yet. will have to be sure

yep, same thing without /update.

If the inserting is the problem, then I might be able to fix that 
with copy to another series in stead. Problem with insert is, when 
you have large series, it has to move the content down the memory.

I'm trying to remove that code right now to see if it improves performance.

now GS won't read the PS file, but the generation is much much faster. 
less than 0.5 secs

Just uncomment after the trim in line 213.

did that

ok :)

Ok, I'll see, if I can make a faster insert...

Henrik, try with new version now:
http://home.tiscali.dk/john.niclasen/postscript/postscript.r

odd, GS won't eat it

oh, error 40 :-)

much faster now and it works

tried a much bigger image. no problems at all.

Great! That's the version to use for now then. Maybe I should put 
an announce in that group?

go ahead :-)

BTW: Does it work for you in preview.app?

Yes, it works in preview now. :-)

so for the other bug: I mentioned earlier that some printers I tried 
it on directly, will cause the printer to pause after the first page 
is printed. Then I need to press paper feed or reset the printer 
to get the rest out. Using Printfile for Windows solves that, but 
that program is really old and I don't want to rely on it in the 
future if my project is moved to Linux clients. I suspect there is 
just one char missing at the end of the PS file, but I don't truly 
know what causes it.

an important detail: I don't think it's single print jobs of multiple 
pages that cause it, but rather multiple single page jobs.

To do anything about it, we need to be able to reproduce that error, 
and see if we can figure out, that might solve it. A way to test 
different things is to edit the ps-files by hand.

that = what

what I do to cause the error is make a ps file with postscript.r 
and then feed it directly to the printer. In windows I print directly 
to LPT1: to produce it. Under Linux I print it via LPR.

I've seen the bug in two separate HP laser printers

no, sorry, under Linux I also print to the device directly. LPR was 
when I used PDF for printing rather than PS.

a simple check: does a PS example from the internet end the same 
way as a postscript.r generated file?

Output from TextEdit printed to a PS file has this in the end:

%%Trailer
%%Pages: 1
%%EOF
^D


The last char (ctrl-D) is hex 04. I think, the comment lines are 
according to "PostScript Language Document Structuring Conventions 
Specification". You can find this document on the net at Adobe. So 
there is a difference in how %%Pages comments are handled. And postscript.r 
doesn't put hex 04 in the end. You could try some of these changes, 
when you have the problem.

I'll give it a shot when I get access to the testing equipment.

Updated the documentation:
http://home.tiscali.dk/john.niclasen/postscript/postscript.html
Added describtion of comment.

Has anyone tried the transformations? There might be an unwanted 
restriction in the implementation. I can't get transformations to 
work for a whole page, only for one path at a time.

I've only tried transformations for single paths, sorry.

Do you use right-aligned text?

it has worked fine in the past, I believe

Yes, but it only worked with integer! text-size. I've added decimal! 
option, and this seems to work too. (sub-unit precision)
I have a new version ready soon.

cool :-)

I needed the decimal! for text size in alignment, because postscript 
work with 72 dot pr. inch by default. Putting text on the page often 
need the text to be with sub-unit precision. It was possible to put 
the text with sub-unit before, but now also alignment can be with 
sub-unit precision.

anyone been working on a postscript table generator for the dialet?

dialect

Geomol. have you been looking at vertically centered text? It could 
be added as a y parameter to 'text, where we already use an x parameter 
for the string box size.

No, I don't think, I've looked at that yet. I might tomorrow.

That is the big problem, basically, that as in going across pages 
(or being wide).

I think I have a crude way to do it for one line.

need it for table cells

I'm working on displaying Qwikis (Wikis) on Cell phones.


It is a connected problem, viewing something intended for one medium 
on another.  

My basic plan is:


- Images - make a thumbnail, then let them click on it to see a larger 
or a list of sizes of their choice


- Tables - Show the name of the table, and then a bias, column or 
row, and offer a search.  Then drill down.


When printing big tables to paper you have to decide what to do if 
the table is simply too big for a single piece of paper.

Put the table at the end on multiple pages?

Put a small version of the table (perhaps unreadable), and say "See 
table on Exhibit X"?
Put the table on multiple pages inline?

Convert the table to something else, for example more like a query 
result, where each row is a chunk of data in a new format?

looks like getting something so simple as the font height is rather 
difficult in postscript

huh?

Geomol, I have the structure change needed for text to support the 
font height, so the vertical centering can be made, but I just can't 
find the postscript commands necessary to obtain the font height.

you define the font height when you set the font.
