Using Microsoft Office 2004 on Mac OS X I tried this test code:
private static void generateRtf( File pictureFile ) throws
IOException, DocumentException {
Document doc = new Document( PageSize.LETTER.rotate() );
RtfWriter2.getInstance( doc, new
FileOutputStream("/tmp/test.rtf") );
try {
doc.open();
Image img = new Jpeg( pictureFile.toURL() );
img.scalePercent( 25f ); //This always seems to be
ignored
doc.add( img );
} finally {
doc.close();
}
}
The RTF images are always displayed at full size. It seems like the
RtfImage class is setting the 'picwgoal' and 'pichgoal' attributes,
but not the 'picscalex' and 'picscaley' attributes. I modified the
source code to add these attributes, and now the images display
correctly with the scaling in Word. Here is the patch for my change:
