[jira] [Commented] (PDFBOX-922) True type PDFont subclass only supports WinAnsiEncoding (hardcoded!)

["Wolfgang Glas (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-922?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13403792#comment-13403792 ] 

Wolfgang Glas commented on PDFBOX-922:
--------------------------------------

I have implemented a glyph extractor, so that subfonts with less than or equal 256 glyphs may be extracted from a large TTF font.

The code may be found there and is licensed under the terms of the apache licenese:

http://svn.clazzes.org/svn/sketch/trunk/pdf/pdf-entities/src/main/java/org/clazzes/sketch/pdf/entities/impl/TTFSubFont.java

We use the the code successfully to write PDFs with full-featured unicode strings by splitting the TTF font to smaller subfonts.

>          Issue Type: New Feature
>          Components: FontBox, PDModel, Writing
>    Affects Versions: 1.3.1

> 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) {}
> 			}
> 		}
