Description Jacobo Aragunde Pérez 2013-10-18 12:26:01 UTC
Created attachment 87822 [details]
Test case

The attached file contains a JPG image embedded into a document as a Draw object. When you export this document to docx the image itself is not saved: if you unzip the docx file you will see that /word/media/ contains a 0-byte file called "image1".

Why is this happening? Look at the code that should save the image file:


if ( rProps.GetOpt( ESCHER_Prop_fillBlip, aStruct ) && m_pTextExport)
    SvMemoryStream aStream;
    int nHeaderSize = 25; // The first bytes are WW8-specific, we're only interested in the PNG
    aStream.Write(aStruct.pBuf + nHeaderSize, aStruct.nPropSize - nHeaderSize);
    Graphic aGraphic;
    GraphicConverter::Import(aStream, aGraphic, CVT_PNG);
    OUString aImageId = m_pTextExport->GetDrawingML().WriteImage( aGraphic );
    pAttrList->add(FSNS(XML_r, XML_id), OUStringToOString(aImageId, RTL_TEXTENCODING_UTF8));

As you can see, CVT_PNG is hard-wired here.

If you had used a PNG image it would have been properly saved but the image wouldn't appear when you open back that saved .docx that's a different bug anyway ;) (probably #65836).

I think this issue is a duplicate of Bug 52226.
I Hope you comments about saving code could help the devs.
