Subject [jira] [Commented] (PDFBOX-922) True type PDFont subclass only supports WinAnsiEncoding (hardcoded!)
Date Fri, 13 Jun 2014 00:53:03 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-922?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14030111#comment-14030111
] 

John Hewson commented on PDFBOX-922:
------------------------------------

If you're using Identity-H for charcode -> CID you're not going to be able to subset the
font because doing so will change the GIDs and the charcodes will need updating (they will
also no longer be the correct Unicode points).

> PDFBox cannot embed Identity-H or Identity-V type TTF fonts in the PDF it creates, making
it impossible to create PDFs in any language apart from English and ones supported in WinAnsiEncoding.
This behaviour is caused because method PDTrueTypeFont.loadTTF has hardcoded WinAnsiEncoding
inside, and there is no Identity-H or Identity-V Encoding classes provided (to set afterwards
via PDFont.setFont() )
> This excludes the following languages plus many others:
> - Greek
> - Bulgarian
> - Swedish
> - Baltic languages
> - Malteze 
> The PDF created contains garbled characters and/or squares.
> Simple test case:
>                 PDDocument doc = null;
> 		try {
> 			doc = new PDDocument();
> 			PDPage page = new PDPage();
> 			doc.addPage(page);
> 			// extract fonts for fields
> 			byte[] arialNorm = extractFont("arial.ttf");
> 			//byte[] arialBold = extractFont("arialbd.ttf"); 
> 			//PDFont font = PDType1Font.HELVETICA;
> 			PDFont font = PDTrueTypeFont.loadTTF(doc, new ByteArrayInputStream(arialNorm));
> 			
> 			PDPageContentStream contentStream = new PDPageContentStream(doc, page);
> 			contentStream.beginText();
> 			contentStream.setFont(font, 12);
> 			contentStream.moveTextPositionByAmount(100, 700);
> 			contentStream.drawString("Hello world from PDFBox ελληνικά"); // text here
may appear garbled; insert any text in Greek or Bulgarian or Malteze
> 			contentStream.endText();
> 			contentStream.close();
> 			doc.save("pdfbox.pdf");
> 			System.out.println(" created!");
> 		} catch (Exception ioe) {
> 			ioe.printStackTrace();
> 		} finally {
> 			if (doc != null) {
> 				try { doc.close(); } catch (Exception e) {}
> 			}
> 		}
