Aspose Slides image extraction issues

Aspose.Slides Product Family

Hello Aspose support
We are experiencing a problem when with extracting image from PPTX file using Aspose.Slides for Java.
The original PPTX file contains embedded EMF/WMF images, like on slide 4, bottom-right.
However extracted image is not complete, please see attachment.
We use:
- Aspose.Slides for Java 8.2.0
- Windows XP
- Red Hat 4.4.7-3, JBoss 5.2.0.1 s
The original and generated files are attached.
Can you please advise if it is a bug in Aspose.Slides 8.2.0? Or we should extract images in some specific way? So far we do it exactly like you propose on your page.

Thank you.
Kind regards,
Michal Wasiak

Hi Michal Wasiak,


Thanks for inquiring Aspose.Slides.

I have observed the inquiry shared by you and request you to please the sample code for extracting the images from presentation. Actually, Aspose.Slides does not offer extracting the images from PPTX presentations. Can you pleases share the sample code that you have used on your end to reproduce the issue. I will use the same on my end to help you further.

Many Thanks,

Hi

Thank you for your answer. First of all the code goes like this:

for (ShapeEx shape : shapeCollection) {
if (shape instanceof AutoShapeEx) {

byte[] imageData = shape.getPictureFormat().getPicture().getImage().getBinaryData();

} else if (shape instanceof PictureFrameEx) {

byte[] imageData = shape.getFillFormat().getPictureFillFormat().getPicture().getImage().getBinaryData();

} else if (shape instanceof OleObjectFrameEx) {
try {

byte[] imageData = shape.getImage().getBinaryData();

} catch (Exception e){
LOGGER.error(“Unparseable OLE object found!”);
}

Some brakcets might be missing, but it’s generally it. Which brings mi to the second thing: under this link Extracting Images from Presentation shapes|Aspose.Slides Documentation you say it’s possible and we do it basically the same way. Could you please clarify if image extraction is or is not supported?

Thanks in advance,
Kind regards,
Michał Wasiak
