ページ順の編集
では，
リスト7 テストを最初に書く
class pdfpages {
function pdfpages(&$pdf) {
}
function makebooklet() {
}
}
class pdfpages_test {
function test1() {
$pdf =& new dummy_pdf("a b c d");
$p =& new pdfpages($pdf);
$p->makebooklet();
asserteq("d a b c", $pdf->pagelist());
$pdf =& new dummy_pdf("a b c d e");
$p =& new pdfpages($pdf);
$p->makebooklet();
asserteq("@ a b @ @ c d e", $pdf->pagelist());
$pdf =& new dummy_pdf("a b c d e f");
$p =& new pdfpages($pdf);
$p->makebooklet();
asserteq("@ a b @ f c d e", $pdf->pagelist());
$pdf =& new dummy_pdf("a b c d e f g");
$p =& new pdfpages($pdf);
$p->makebooklet();
asserteq("@ a b g f c d e", $pdf->pagelist());
$pdf =& new dummy_pdf("a b c d e f g h");
$p =& new pdfpages($pdf);
$p->makebooklet();
asserteq("h a b g f c d e", $pdf->pagelist());
}
}
注意点ですが，
ちなみにPHP5以降では，
実行すると，
$ php run.php ........ Expected: "dabc" Fonud: "abcd" ---- test failed. $
では，
リスト8 makebookletを書く
class pdfpages {
var $pdf = null;
function pdfpages(&$pdf) {
$this->pdf =& $pdf;
}
function &newblankpage() {
$page =& $this->pdf->newPage();
return $page;
}
function makebooklet() {
while ((count($this->pdf->pages) % 4))
$this->pdf->pages[] =& $this->newblankpage();
$newpages = array();
$left = count($this->pdf->pages) - 1;
$right = 0;
while ($right < $left) {
$newpages[] =& $this->pdf->pages[$left--];
$newpages[] =& $this->pdf->pages[$right++];
$newpages[] =& $this->pdf->pages[$right++];
$newpages[] =& $this->pdf->pages[$left--];
}
$this->pdf->pages = $newpages;
}
}
実行すると，
$ php run.php ............. test successed. $
あとは，

また，
今回はユーザインターフェースについては相当手を抜いたので，
