Message-ID: <20060113144930.GA47933@dogma.freebsd-uk.eu.org>

I have a few pages of php to generate a pdf report with charts.  I'm looking
to move to Lisp for the core app, but I'm not looking forward to porting the
php.

I noticed cl-pdf seems to have graphing support built in.  Is this the case?
Also, how well does it integrate with UCW or Araneida-served pages?

Yes. See chart.lisp

Very well. Just generate the PDF in memory and then use it to make your HTTP reply. It's
more an UCW or Araneida question IMO.

In SBCL with Unicode, you might need to dump it into a file, then read back,
because of character/byte issues. This is what I use (I intentionally do not
use ".pdf" extension):

(defun doc-to-uniq-tmpfile (doc)
  (let ((pathname
         (loop
            for name = (random-string 10)
            for pathname = (merge-pathnames
                            (make-pathname :directory '(:absolute "tmp"))
                            (make-pathname :name name)) ; NOTE: do not set type
            while (probe-file pathname)
            finally (return pathname))))
    (pdf:write-document pathname doc)
    pathname))

(defun doc-to-pdf (doc) ; sb-unicode is a pain...
  (let ((pathname (doc-to-uniq-tmpfile doc)))
    (prog1
        (with-open-file (in pathname :element-type :default)
          (let ((bytes (make-array
                        (file-length in) :element-type '(unsigned-byte 8))))
            (read-sequence bytes in)
            bytes))
      (delete-file pathname))))

I guess I can just write it to a file instead.  That should work fine.

Ah, ok.  Is there an online reference to pdf commands I can check when I have
these questions?  I'd even be willing to submit docstrings as I work my way
through the library.  It's much better than Cpdf for php, but a good deal
harder to figure out.  ;-)

Hi all,

if I want to build a complex page and call several functions to create the
pages, how do I make sure each call has the correct context?

Is it enough just to wrap each function in with-document or with-page?  That
doesn't seem like it would work.

Well, with-page and with document are macros not functions.

You have to use
(with-document
    (with-page...)
    (with-page...)
    (with-page...)
...)

The with-page can be in some function though

You don't call with-document and with-page, they are macros not functions so they are
expanded not called.
Look at: http://www.lisp.org/HyperSpec/Body/sec_3-1-2-1-2-2.html for precisions.
There is probably a chapter on macros in PCL: http://www.cl-user.net/asp/web-sites/pcl

The only thing I see between rotation and keep-aspect-ratio is "&optional".

I was looking at CL-PDF on Digitool's MCL and there are several  
places in the code that assume #\/ is the directory separator.

I'll attach a completed patch using logical pathnames once I've got  
it all working.

Also, if there is interest in making CL-PDF (and CL-Typesetting) ASDF- 
Installable, I'd be happy to do the work... The only putative  
disadvantage is that the packages would be signed with my key instead  
of Marc's.

Is it really necesssarry to use logical pathnames--it seems like a  
big pain to require folks to set up logical pathnames just to use CL- 
PDF. Can't the inappropriate uses of #\/ be fixed by basic pathname  
calculus?

Sorry to be confusing. Yes. It's just pathname calculus (that sounds  
so fancy!) with make-pathname and merge-pathnames, etc.

Most of the graphical operators have the same name than in the Adobe PDF reference manual.
So you should start by looking at it. (you can download it on Adobe web site). You can
also start with the examples.

If you want more high level functions for text, you need to look at cl-typesetting.

Subject: [cl-pdf-devel] Adding options to x-axis
Message-ID: <20060119165600.GA46422@dogma.freebsd-uk.eu.org>

There are 3 features I was wondering about.  Either I could try to subclass
and add them myself, or I could see if they are hidden somewhere I've missed
or even being implemented right now.

1.  Text labels rather than numbers for x-axis
2.  Vertical lines on chart for x-axis.
3.  Exact length for x-axis, rather than rounding.

I have a chart showing the values of 21 characteristics.  I need to label the
axis with the characteristic abbreviations, and I'd like the axis to end with
the last one, rather than round up to 25.

Is this possible at the moment, or should I subclass and add an :after?

The note in the source says chart.lisp is in alpha state.  Is anyone working
on adding new features?  Or is it pretty much static at the moment?

Sorry, I misspoke.  I meant dx and dy in (draw-image).  Obviously they have
something to do with sizing the image, but are they just approximate ratios
that are corrected if keep-aspect-ratio is t?

For 1, use a format string with the Tilde Slash directive:
http://www.lisp.org/HyperSpec/Body/sec_22-3-5-4.html

For 2, use pre-draw-chart-fn of post-draw-chart-fn to draw before or after the chart.

For 3 you will have to change some code.

In this case, some of dx or dy is effectively decreased to fit the image
inside the rectangle delineated by the original values of dx and dx.

It's not alpha state anymore. I use it a lot in production so I will remove that comment.

Improvements and new features are always welcome of course. ;-)

Thanks Gary!
BTW this reminds me that I didn't reply to your previous email. :-(
I'm sorry about that. I am in an awful rush to finish a current work for next week.

I find it's a good idea. This is on my todo list but I've managed to push it further every
time... ;-)
(I even found again the passphrase I lost for my signing key ;-)
I think it will be better if I sign it with my own key so that I can integrate this to my
current make-release script which is called each time I commit to the code repository.

What an awesome feature!  Extensible format strings!

I have a lisp style question about the code.  What is the purpose of 
(apply #'set-rgb-fill (foo bar))

when you could just call
(set-rgb-fill (foo bar))
?

I don't quite get the apply here, as well as when it is used with
make-instance.

Or maybe the other way around, I forget.

Did you make the PDF with CL-PDF?  Perhaps you could share the code that
you used to make it?  At a guess, it sounds like you might have mixed up
your use of PDF:IN-TEXT-MODE.

FWIW, I doubt that the operating system is an important factor here.
Perhaps the reader you used on Windows is simply less tolerant of broken
files.

One nice tool for debugging PDF files is xpdf with the -cmd option.

Most definitely.  And I love it on Unix!

: you used to make it?  At a guess, it sounds like you might have mixed up
: your use of PDF:IN-TEXT-MODE.

That's definitely possible.  I have no idea what in-text-mode does, and the
difference between move-to and move-text and move-to-next-line and
show-text-on-next-line are.  But I'm learning.

: FWIW, I doubt that the operating system is an important factor here.
: Perhaps the reader you used on Windows is simply less tolerant of broken
: files.

I updated Acrobat Reader on the machine, but no change.

: One nice tool for debugging PDF files is xpdf with the -cmd option.

I'll try it.  Thanks!

It's not the same:

My client wants xy-plots, rather than histograms, so I definitely need to do
some customizing of the x-axis.  I have the points labeled with text rather
than numbers, but I need to adjust their position a bit more.  It looks like
label-position and label-rotation are not yet implemented, correct?

Also, to force the x-axis to end on axis-max rather than a nicer rounded
value, I need to change compute-scale, correct?

Yes.

Yes and the draw-object method too.
At the beginning it was like that. The locked-values slot is for this but it's like
label-rotation ;-)

Hello again Marc,

I'm trying to figure out the text matrix options.  The reason I'm having
trouble with all of these commands is the php library I learned pdf with
wrapped all of these commands.  For example, showing text had options for
position and angle.  I need to figure out how to show text at a certain angle.

Rotate is good, but not quite exactly what I need, because the next text shown
after a rotate is still on the old coordinate system.  I need to show text
labels along the x-axis, but rotated about 45 degrees, so longer words will
fit.  My problem with rotate is the text doesn't stay on the x-axis
horizontally, but keeps going up at 45 degrees.

Try this:

(pdf:rotate 10)
(pdf:draw-text "Hello,")
(pdf:rotate -10)

(pdf:rotate 10)
(pdf:draw-text "world!")
(pdf:rotate -10)

I want the H in Hello and the w in world to be on the same line.  How can I do
this?

Is there a function to draw a large amount of text in a certain area that
automatically handles word wrap?

Please take a look at text.lisp.
