[reportlab-users] Trouble using TTF font

[Satish Kalipatnapu]

You can convert the TTF to PFB+AFM using tools like fontforge.

Subject: [reportlab-users] Trouble using TTF font


Below is code and traceback for an attempt to use a TTF font, and some
additional information. Most recent stable RenderPM (1.01), and
reportlab .... Any idea what is going wrong?? Are certain TTF fonts not
supported?

I'm pretty sure that this code actually finds the font on the
filesystem, because I see all the font data loaded into the variable
socketFont.

Thanks; peace,
George



****************************************************************
CODE
****************************************************************
facename = "Socket"
folder = "/usr/local/zope/instance1/var/fonts"
ttffile = "Socket.TTF"
fontsize = 21
reportlab.rl_config.TTFSearchPath.append(folder)

socketFont = TTFont(facename, ttffile)
pdfmetrics.registerFont(socketFont)
c = renderPM.PMCanvas(400, 50)
c.setFont(facename, fontsize)

****************************************************************
TRACEBACK
****************************************************************
Warn: Can't find .pfb for face 'Socket'
Traceback (most recent call last):
  File "test.py", line 19, in ?

reportlab.graphics.renderPM.RenderPMError: Can't setFont(Socket) missing
the T1 files? Originally exceptions.AttributeError: TTEncoding instance
has no attribute 'vector'


****************************************************************
ADDITIONAL INFORMATION
****************************************************************
If it helps, using a python debugger the following occurs:

(1) In reportlab/graphics/renderPM.py(195)_setFont(), the code
   try:
     gs.setFont(fontName, fontSize)
fails with Error "Can't find font!"

(2) So instead, renderPM tries to execute
 
_renderPM.makeT1Font(fontName,f.face.findT1File(),f.encoding.vector,open
_and_read)

(3) But f.encoding is {'name': 'UTF-8'}, without a 'vector' attribute,
causing an AttributeError.  f.encoding is first set in the
initialization
  socketFont = TTFont(facename, ttffile)
which includes the line
  encoding = TTEncoding()
which intializes encoding to {'name': 'UTF-8'}.

Should the error in (1) even occur? What is going on in (3)?
