PPTX in PHP

Greetings,


I’m successfully creating thumbnails from PPT files using Aspose and PHP, but I can’t seem to be able to get the same process going with PPTX files. The file seems to open correctly (or at least no errors are thrown) using the following command:
$pres =
new Java(“com.aspose.slides.pptx.PresentationEx”, $file);

However, any attempt to use that object results in errors:
$lastSlidePosition = $pres->getSlides()->size();
$lastSlidePosition =
$pres->getSlides()->getLastSlidePosition();
$slide = $pres->getSlides()->get($i);

Note that all of these calls work fine when using a PPT file, although I instantiate it with a call like this:
$pres=new Java(“com.aspose.slides.Presentation”,"$file");

I’ve scoured the aspose site and google in general for a working example of PHP opening an PPTX file, but have not found anything. Is such an example available, or can such an example be provided here?

In case it’s pertinent, the error I’m receiving seems a bit indeterminate to me, but I’m not a Java expert. Here’s the top of the error output by the exception object captured by my try-catch block:

Hi Michael,


I have worked with the scenario shared by you and have been able to reproduce the issue specified using Aspose.Slides for Java 2.7.0. An issue with ID 32859 has been created in our issue tracking system to further investigate and resolve the issue. I also like to share that, "$pres->getSlides()->getLastSlidePosition(); " properties does not exist for PPTX.

We are sorry for your inconvenience,

The issues you have found earlier (filed as SLIDESJAVA-32859) have been fixed in this update.
