Summary: FILESAVE: docx: JPG images not saved on export
Severity: normal
Classification: Unclassified
OS: All
Reporter: jaragu...@igalia.com
Hardware: Other

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:
oox/source/export/vmlexport.cxx:559
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);
aStream.Seek(0);
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).
