Philippe, the zip attachment didn't make its way to us but from what you're telling and a look at the code, I can indeed see that when writing a raster with rotational terms in the geotransform matrix, and vectors, the vector writing part will not work correctly taking into account those rotational terms. A workaround would be to use gdalwarp to create a raster that is "north-up", before creating the PDF.
