Re: [cairo] Pango font thickness

[mpsuzuki hiroshima-u ac jp]

Hi,

Thank you for sending sample picture. Oops, I ought to have
find that your sample code using "stroke" operator of cairo.
I think the issue you report is not font selection -
the heavy weight you got is because the path of the glyph
outline is drawn by the thick line. If you generate a PDF
by PdfSurface, the PDF has no embedded font, the text is
drawn as a graphics.

I'm unfamiliar with APIs of cairomm, but I guess there might
be some "show" like operator that renders the font strictly.
Please search for it, or tune the width of line to thin.

Regards,
mpsuzuki
