Description
I'm trying to use the PHPPresentation Reader to process a plethora of Powerpoint 2007 presentations and have noticed that it doesn't appear to correctly attribute bullets...
If you look at the following XML, there are two columns on a simple page (image attached below so you can see what it looks like).
The first column has a list of text and the second is a list of bullets. Yet reader returns two lists of text because it makes the assumption that any paragraph has the bullet type of TYPE_NONE.
But looking at the XML, it shows that the text without bullets is explicitly defined as '<a:buNone/>'. Where as the text that is a bullet has nothing marking it as such....

Is anyone who knows the spec able to please comment on this - as it's not as simple as defaulting to TYPE_BULLET in the loadParagraph function in PowerPoint2007.php though that seems to improve the situation.
ie, quickly experimenting with the code by adding in a $oParagraph->getBulletStyle()->setBulletType(Bullet::TYPE_BULLET); rather than a TYPE_NONE and then setting it explicitly to NONE if a a:buNone is detected:
...
$oElementSpacingAfter = $document->getElement('a:spcAft/a:spcPts', $oSubElement);
if ($oElementSpacingAfter instanceof DOMElement) {
$oParagraph->setSpacingAfter($oElementSpacingAfter->getAttribute('val') / 100);
}
$oParagraph->getBulletStyle()->setBulletType(Bullet::TYPE_BULLET);
$oElementBuFont = $document->getElement('a:buNone', $oSubElement);
if ($oElementBuFont instanceof DOMElement) {
$oParagraph->getBulletStyle()->setBulletType(Bullet::TYPE_NONE);
}
$oElementBuFont = $document->getElement('a:buFont', $oSubElement);
if ($oElementBuFont instanceof DOMElement) {
if ($oElementBuFont->hasAttribute('typeface')) {
$oParagraph->getBulletStyle()->setBulletFont($oElementBuFont->getAttribute('typeface'));
}
}
$oElementBuChar = $document->getElement('a:buChar', $oSubElement);
if ($oElementBuChar instanceof DOMElement) {
$oParagraph->getBulletStyle()->setBulletType(Bullet::TYPE_BULLET);
if ($oElementBuChar->hasAttribute('char')) {
$oParagraph->getBulletStyle()->setBulletChar($oElementBuChar->getAttribute('char'));
}
}
...
Thank you,
Mark
