that is possible using penalties.

I think that might be the simple answer, actually. It is only when 
the software makes a blunder with intelligent splitting that it becomes 
a problem. If the user can force a row to always remain together 
that would solve most of those problems.

a paragraph of two lines already has a big penalty for being split. 
so generally it is kept together.

basically you're saying: either you allow vertical alignment, or 
cell splitting.

which is one possible solution.

(Ok, so the algorithm looks for the lowest penalties first.)

the algorithm produces the layout with the least total demerits.

Yes, I think it will be the easiest and simplest solution.

(in some cases it doesn't, because it would require too much time, 
but the user decides this, by setting the tolerance)

(That's not to say people won't be looking for more complex interactions, 
but I think the simplest way solves most complaints the quickest.)

ok, i will think more about the problem (still hope to find some 
kind of nice solution), and see what others think too.

Cool, good luck.

What do the current LaTeX to DPF programs do?

Reichart, I'm still learning about TeX, but I'll guess, LaTeX to 
PDF take output from LaTeX (a TeX document) and convert it to the 
PDF format. To see output from LaTeX, you still need a TeX engine 
to view the document in the final form. Convert it to PDF, and you 
just need a PDF viewer.

About tables? TeX only handles very simple tables. Absolutely not 
enough to get QML tables there.

(you can do almost everything with TeX by using tricks, but you basically 
need to layout the table manually. it is not able to do that automatically 
- something that we need to do instead.)

That was what I figured.

update: added preliminary table support.

(the table dialect is still very basic, just for testing. table layout 
seems to work well, uses the total-fit algorithm and should create 
optimal layouts in most usual cases. there are boundary cases where 
it can fail, but i hope we won't need to worry about them. check 
test.pdf for an example of a table.)

Somehow I lost the link to the PDF-Maker test site. Would someone 
please post it.

For whatever it is worth, Gabriele, I use PDF-Maker regularly. It 
is core to some of my most important scripts. So, I very much appreciate 
your work.

Louis, what is your input lanaguge for PDFMaker?

Currently only English.  But I'm needing to print Greek, Indonesian, 
and English mixed on the same page. Also, Hebrew, Indonesian, English 
on the same page. To be more specific,  a line of Greek, then a line 
of Indonesian, then a line of English, then back to a line of Greek, 
and so on.

update: added embedded tables (i.e. tables between paragraphs)

this also means that you can have a table inside a table cell - not 
tested yet, but maybe it works. ;)

I like the cautious optimism :)    Looking good.

LOL, I meant as in HTML, MakeDoc, etc.

reichart, i'm pretty sure he's using the pdf maker dialect directly.

Ah.  What is it?  I have not played with PDF Maker

it's much lower level than MD or QML. It's a REBOL dialect, not a 
ML.

update: text colors, fixed table parsing bug

i have tested table inside table cell, it works fine. (see test.pdf)

Cool. Getting better.

update: table options

update: graphic commands, cell decorations

(cell decorations is a superset of table borders, cell background 
etc)

see test.pdf

Funny looking table borders ! :)

you can just use any graphics for cells. for example QML can produce 
boxes with rounded corners and shadows.

a quick scan here ... I do not see anything for taking a .pdf and 
converting it to something like an image or some markup.  Does anyone 
know of something that converts a .pdf to generic postscript (like 
for GSView) or to convert to native REBOL format?  Thanks.

A way to convert content, especially graphic from .pdf to something 
useful.

photoshop will strip out graphics files if thats what you need

so I can load a .pdf and make a high res bitmap?

found http://www.pstoedit.net/pstoeditwhich can do vector graphics...maybe 
this will help...and some point would be cool to do these in REBOL.

Graham, thanks.

PDFCreator

 


Overview: PDFCreator is an application for converting documents into 
Portable Document Format (PDF) format on Microsoft Windows operating 
system. Once installed, it allows the user to select PDFCreator as 
their printer, allowing almost any application to print to PDF, PNG, 
JPEG, BMP, PCX, TIFF and EPS format.


Besides being installed as a printer driver, PDFCreator can be associated 
with .ps files to manually convert Postscript to PDF format.

Needs Ghostscript doesn't it?
