Hi all.
This is my first time signalling a bug. I apologize if I'm doing this in some
wrong way.
I found an error in the kerning calculations while scaling the whole document.
I made a simple test-case python program:
---------------------------------------------------------------------------------
import pango, cairo, pangocairo
sf = 72 / 25.4
surface = cairo.PDFSurface('/tmp/test.pdf', 210*sf, 297*sf)
ctx = cairo.Context(surface)
ctx.scale(sf, sf)
pctx = pangocairo.CairoContext(ctx)
pctx.new_path()
pctx.move_to(20, 20)
layout = pctx.create_layout()
layout.set_text('Ve Te To')
pctx.show_layout(layout)
surface.finish()
---------------------------------------------------------------------------------
As you can see in the /tmp/test.pdf file, the lowercase letters are too near
to the preceding uppercase letters. This behaviour can be accentuated
increasing the value of the sf variable. With sf = 1, the letter kerning
seems to be ok.
I'm running cairo-1.8.8, pango-1.24.5, python-2.6.2, pycairo-1.8.8.
Thanks for you help!
Ciao.
P.S.: there is a way to disable kerning?
