           Summary: Unsupported picture type: 7
           Product: POI
           Version: 3.0-dev
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HSLF
        AssignedTo: poi-dev@jakarta.apache.org
        ReportedBy: nick@torchbox.com


On <http://www.iisd.org/pdf/2004/sci_cec.ppt>, there's a picture of type 7.
Previously this was throwing a Runtime exception in 

java.lang.RuntimeException: Unsupported picture type: 7
        at
org.apache.poi.hslf.usermodel.PictureData.create(PictureData.java:178)
        at
org.apache.poi.hslf.HSLFSlideShow.readPictures(HSLFSlideShow.java:274)
        at org.apache.poi.hslf.HSLFSlideShow.<init>(HSLFSlideShow.java:134)

I've changed the code to print a warning but not die, but it might be good to
support picture type 7 if we can figure out what it is, or otherwise just
blindly carry the picture data around in a dummy record.

Hi Nick,

I implemented the support of DIB in HSLF.

Now HSLF can handle all types of pictures defined in the escher documentation:
EMF, WMF, PICT, JPEG, PNG and DIB.

The code works fine with http://www.iisd.org/pdf/2004/sci_cec.ppt, all images
including DIBs are extracted.

Regards, 
Yegor

type=7 is Windows DIB. I thought it is obsolete and not supported. 

In PowerPoint 1997 and later DIBs are automatically converted into PNG. 
I will look into it later. 
Thanks.
