In the first case you have 100 subsets with different names and they all show up. In the second case you still have 100 fonts but as the names are the same (full embedd) only 3 show up.

Sorry if I'm beating a dead horse, just trying to understand.

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); } }
