[reportlab-users] KeyError: Vera-Bold

[Johannes Schönberger]

Hi everybody,

I didn't know, if this is also a support "channel", so I apologize if so.

I always get a KeyError, when adding my own fonts, but I have no idea why... my code:

font_dir = os.path.abspath(os.path.dirname(__file__))
for font in ['Vera', 'Arial']:
    pdfmetrics.registerFont(TTFont(font,
        os.path.join(font_dir, 'fonts/%s.ttf' % font)))
    addMapping(font, 0, 0, '%s' % font)
    pdfmetrics.registerFont(TTFont('%s-Bold',
        os.path.join(font_dir, 'fonts/%s Bold.ttf' % font)))
    addMapping(font, 1, 0, '%s-Bold' % font)
    pdfmetrics.registerFont(TTFont('%s-Italic' % font,
        os.path.join(font_dir, 'fonts/%s Italic.ttf' % font)))
    addMapping(font, 0, 1, '%s-Italic' % font)
    pdfmetrics.registerFont(TTFont('%s-BoldItalic' % font,
        os.path.join(font_dir, 'fonts/%s BoldItalic.ttf' % font)))
    addMapping(font, 1, 1, '%s-BoldItalic' % font)

If I try to add a paragraph via platypus with the following content: "Hello <b>World</b>", I get this traceback: (without the <b>-tags it works fine)
I hope you can help me, thank you very much in advance!

In [3]: generate.build_doc('test.pdf', text_before='<b>Hello</b> World')
