[jira] [Commented] (PDFBOX-3708) hasGlyph() contradicts encode()
[ https://issues.apache.org/jira/browse/PDFBOX-3708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15895616#comment-15895616 ]
Andreas Lehmkühler commented on PDFBOX-3708:
--------------------------------------------
IMHO it is a javadoc issue. The parameter isn't meant to be an unicode character code but a PDF internal charcater code, see PDFStreamEngine#showGlyph
> hasGlyph() contradicts encode()
> -------------------------------

> Key: PDFBOX-3708
> URL: https://issues.apache.org/jira/browse/PDFBOX-3708
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.4, 2.1.0
> Reporter: Tilman Hausherr
>
> {code}
> PDDocument doc = new PDDocument();
> PDType0Font font = PDType0Font.load(doc, new FileInputStream("c:/windows/fonts/arial.ttf"));
> System.out.println(font.hasGlyph('\n'));
> PDPage page = new PDPage();
> doc.addPage(page);
> PDPageContentStream cs = new PDPageContentStream(doc, page);
> cs.beginText();
> cs.setFont(font, 100);
> cs.showText("\n");
> {code}
> The output:
> {code}
> true
> Exception in thread "main" java.lang.IllegalArgumentException: No glyph for U+000A in font ArialMT
> at org.apache.pdfbox.pdmodel.font.PDCIDFontType2.encode(PDCIDFontType2.java:402)
> at org.apache.pdfbox.pdmodel.font.PDType0Font.encode(PDType0Font.java:351)
> at org.apache.pdfbox.pdmodel.font.PDFont.encode(PDFont.java:316)
> at org.apache.pdfbox.pdmodel.PDPageContentStream.showText(PDPageContentStream.java:362)
> {code}
> Either this is a bug in hasGlyph(), or it is a documentation (javadoc) problem, e.g. because the parameter to hasGlyph isn't a character code but something else, then this should be clarified.
