[Sugar-devel] FWD: Sugar font size & wiki

[Walter Bender]

Here's what I do in Turtle Art:


def draw_text(t, label, x, y, size, w):
    t.gc.set_foreground(t.tw.textcolor)
    fd = pango.FontDescription('Sans')
    fd.set_size(int(size)*pango.SCALE)
    pl = t.tw.window.create_pango_layout(str(label))
    pl.set_font_description(fd)
    pl.set_width(int(w)*pango.SCALE)
    t.canvas.image.draw_layout(t.gc,int(x),int(y),pl)

I use a scale factor of 1.6 to convert between XO and non-XO displays.
