I debugged the PDF a little. FWIW, the following code (using iText)
takes it to 9MB:
public static void main(String args[]) throws Exception {
Document document = new Document();
PdfSmartCopy copy = new PdfSmartCopy(document, new
FileOutputStream("/home/rmuir/Downloads/test.pdf"));
//copy.setCompressionLevel(9);
//copy.setFullCompression();
document.open();
PdfReader reader = new
PdfReader("/home/rmuir/Downloads/apache-solr-ref-guide-4.7.pdf");
int pages = reader.getNumberOfPages();
for (int i = 0; i < pages; i++) {
PdfImportedPage page = copy.getImportedPage(reader, i+1);
copy.addPage(page);
}
copy.freeReader(reader);
reader.close();
document.close();
}
