[cl-typesetting-devel] Drawing multiple pages woes.

[Marc Battyani]

[I'm sorry but yesterday, I missed Erik's message with the example, so my
advice to try with the example was out of sync :(
I take this example as the test base now.]

In fact the problem is related to the fact that the table was not inline.
When a table is not inline, it is put in an hbox and the v-split function
will not split it.
So with (table (:col-widths '(100 200) :splittable-p 1 :inline t) the table
is split and there is no infinite loop.

The problem is that the split is not correct.

(defun multi-page-hello (&optional (file #P"/tmp/hello.pdf"))
   (pdf:with-document ()
     (let ((content
   (compile-text ()
     (vspace 100)
     (table (:col-widths '(100 200) :splittable-p 1 :inline t)  ;;; start

            (dotimes (time 50)
              (row ()
                   (cell ()
                         (paragraph () (put-string (format nil "test ~d"
time)))))))  ;;; end Erik changes
     :eol
     (paragraph (:h-align :center :font "Helvetica-Bold" :font-size 50
                          :color '(0.0 0 0.8))
                "cl-typesetting" :eol
                (vspace 2)
                (hrule :dy 1)
                (with-style (:font "Times-Italic" :font-size 26)
                  "The cool Common Lisp typesetting system")
                (vspace 50)
                (with-style (:font "Times-Italic" :font-size 36 :color '(0.0
0

0.8))
                  (dotimes (i 100)
                    (put-string "Hello World!")(new-line)))))))
       (loop while (boxes content) do
             (pdf:with-page ()
               (pdf:set-line-width 0.1)
               (draw-block content 20 800 545 700))))
     (pdf:write-document file)))

In the multi-page-example the table is correctly splitted though.

Yes the lack of time is the major problem :(
Have you advanced the HTML renderer ?
