How to properly copy-paste a slide with Apache POI
I'm trying to duplicate a slide in Apache POI.
Depending on the slide content I have three cases
- The duplication succeeds (also for some slides with XSLFPictureShape objects)
I get NullPointerException while POI is trying to copy a XSLFPictureShape (stacktrace follows)
Exception in thread "main" java.lang.NullPointerException
at org.apache.poi.xslf.usermodel.XSLFSheet.importBlip(XSLFSheet.java:651)
at org.apache.poi.xslf.usermodel.XSLFPictureShape.copy(XSLFPictureShape.java:202)
at org.apache.poi.xslf.usermodel.XSLFSheet.wipeAndReinitialize(XSLFSheet.java:452)
at org.apache.poi.xslf.usermodel.XSLFSheet.importContent(XSLFSheet.java:431)
at org.apache.poi.xslf.usermodel.XSLFSlide.importContent(XSLFSlide.java:294)
...
I get ClassCastException while POI is trying to copy a XSLFPictureShape (stacktrace follows)
Exception in thread "main" java.lang.ClassCastException: org.apache.poi.ooxml.POIXMLDocumentPart cannot be cast to org.apache.poi.xslf.usermodel.XSLFPictureData
at org.apache.poi.xslf.usermodel.XSLFSheet.importBlip(XSLFSheet.java:651)
at org.apache.poi.xslf.usermodel.XSLFPictureShape.copy(XSLFPictureShape.java:223)
at org.apache.poi.xslf.usermodel.XSLFSheet.wipeAndReinitialize(XSLFSheet.java:452)
at org.apache.poi.xslf.usermodel.XSLFSheet.importContent(XSLFSheet.java:431)
at org.apache.poi.xslf.usermodel.XSLFSlide.importContent(XSLFSlide.java:294)
...
What am I doing wrong?
UPDATE
I have found that the NullPointerException issue of point #2 was due to a corrupted pptx file (maybe because it has been edited once with a mac?)
The only real issue I have now is the one at point #3
UPDATE
It seems that ClassCastException of point #3 was due to some pictures with "artistic effects" applied on them, that are currently unsupported by Apache POI. Copying the pictures in PowerPoint and pasting "as image" removes the effect and the issue.
