No mistery. As you have a single glyph the subset will be the same and PdfSmartCopy will include a single instance of the file. The difference comes from the width table that has a single element in the case of the subset and 256 entries for the full embed.

Seems "wrong" to see the same font embedded multiple times yet end up with a smaller document. Short of Document Props > Fonts scrolling forever, is there any harm in letting it embed the subset. My main goal was to reduce file size after concat'ing several (~30,000) PDFs.

I created 100 identical pdfs that uses this font and then used smartcopy to merge all 100 pages. The resulting PDF is 184KB and when I look at the document properties, it shows the font 100 times (presumably because it was an embedded subset). I added "myFont.setSubset(false);" and reran the test. Now when I view the properties of the merged pdf, I only see my font once (as expected), yet the size of my merged PDF grew to 327KB! (not expected) As I understood it, SmartCopy didn't reuse fonts that were subsets. public class Fonts { public static final Font VISA; public static final Font SCORECARD; public static final Font MICR; static { BaseFont _visa = null; BaseFont _scorecard = null; BaseFont _micr = null; try { _visa = BaseFont.createFont("/fonts/CREDITCARD.ttf", BaseFont.WINANSI, BaseFont.EMBEDDED); _visa.setSubset(false); // INCREASES FILE SIZE?!?! _scorecard = BaseFont.createFont("/fonts/SCORECARD.ttf", BaseFont.WINANSI, BaseFont.EMBEDDED); _scorecard.setSubset(false); // INCREASES FILE SIZE?!?! _micr = BaseFont.createFont("/fonts/OCRAEXT.ttf", BaseFont.WINANSI, BaseFont.EMBEDDED); _micr.setSubset(false); // INCREASES FILE SIZE?!?! } catch (Exception e) { e.printStackTrace(); System.exit(1); } VISA = new Font(_visa, 12); SCORECARD = new Font(_scorecard, 12); MICR = new Font(_micr, 12); } } private void generateStatements() { try { log.info("begin generating statements"); Document d = new Document(); PdfSmartCopy copy = new PdfSmartCopy(d, new FileOutputStream("C:/temp/aMerged.pdf")); d.open(); for (int i = 1; i <= 100; i++) { Document document = new Document(); PdfWriter.getInstance(document, new FileOutputStream("C:/temp/test" + i + ".pdf")); document.open(); document.add(new Paragraph("LARGE FONTS", Fonts.NORMAL)); document.add(new Paragraph("testing our font class", Fonts.LARGE_NORMAL)); document.add(new Paragraph("testing our font class", Fonts.LARGE_BOLD)); document.add(new Paragraph("testing our font class", Fonts.LARGE_UNDERLINE)); document.add(new Paragraph("testing our font class", Fonts.LARGE_ITALIC)); document.add(new Paragraph("\n\nNORMAL FONTS", Fonts.NORMAL)); document.add(new Paragraph("testing our font class", Fonts.NORMAL)); document.add(new Paragraph("testing our font class", Fonts.BOLD)); document.add(new Paragraph("testing our font class", Fonts.UNDERLINE)); document.add(new Paragraph("testing our font class", Fonts.ITALIC)); document.add(new Paragraph("\n\nSMALL FONTS", Fonts.NORMAL)); document.add(new Paragraph("testing our font class", Fonts.SMALL_NORMAL)); document.add(new Paragraph("testing our font class", Fonts.SMALL_BOLD)); document.add(new Paragraph("testing our font class", Fonts.SMALL_UNDERLINE)); document.add(new Paragraph("testing our font class", Fonts.SMALL_ITALIC)); document.add(new Paragraph("\n\nCOLORED FONTS", Fonts.NORMAL)); document.add(new Paragraph("testing our font class", Fonts.PEFCU_RED_NORMAL)); document.add(new Paragraph("\n\nWHITE FONTS", Fonts.NORMAL)); Chunk chunk = new Chunk("testing our font class", Fonts.WHITE_NORMAL); chunk.setBackground(Colors.BLACK); document.add(new Paragraph(chunk)); Chunk chunk2 = new Chunk("testing our font class", Fonts.WHITE_BOLD); chunk2.setBackground(Colors.BLACK); document.add(new Paragraph(chunk2)); document.add(new Paragraph("\n\nSPECIAL FONTS", Fonts.NORMAL)); document.add(new Paragraph("A", Fonts.VISA)); document.add(new Paragraph("A", Fonts.SCORECARD)); document.add(new Paragraph("1 2 3 4 5 6 7 8 9 0", Fonts.MICR)); document.close(); log.info("merging C:/temp/test" + i + ".pdf"); PdfReader reader = new PdfReader("C:/temp/test" + i + ".pdf"); ByteArrayOutputStream baos = new ByteArrayOutputStream(); PdfStamper stamper = new PdfStamper(reader, baos); stamper.close(); reader = new PdfReader(baos.toByteArray()); copy.addPage(copy.getImportedPage(reader, 1)); } d.close(); log.info("finished generating statements"); } catch (Exception e) { log.fatal(e.getMessage(), e); } }
