Not able to convert PPTX to JPEG Image having animated slides

Aspose.Slides Product Family

Hi,

I am using Aspose.Slides for Java-2.5.0 to convert a PPTX to JPEG image using below code.

try {
// Instantiate a Presentation object that represents a PPT file
PresentationEx pptxPresentation = new PresentationEx(inputFilePath);

// Access the first slide
SlidesEx slds = pptxPresentation.getSlides();
int totalSlides = slds.size();

for (int i = 0; i < totalSlides; i++) {
// Create a full scale image
BufferedImage img = slds.get(i).getThumbnail(1f, 1f);

// Save the image to disk in JPEG format
ImageIO.write(img, “jpeg”, new File(outputFilePath
+ “\thumbnail” + i + “.jpg”));
}
} catch (Exception e) {
e.printStackTrace();
}

It worked fine for the PPTX file without animation. But when I’ve tried with the file having animation in it. Its’ giving me below error.

com.aspose.slides.pptx.PptxException$PptxReadException: Reading animation group failed.

I’ve attached the PPTX file as well.

NOTE : PPT to JPEG is working fine with animation as well.

Can you please tell me what is the issue with it ? Am i doing anything wrong ?

Thanks

Hi Mudassir,

Thanks for the reply.

And how much time do you think will it take to resolve the issue. Any rough timeline.

Why am i asking this, Because we are looking forward to use Aspose Slides for one of our project for converting PPT/PPTX to JPEG conversion, IF issue gets resolved in near future.

Thanks
