[cairo] Pango font thickness

[Edder <edder tkwsping nl>]

Hi all,

I am trying to make a simple plotting library using cairomm and
pangomm. Currently I have problems with the fonts though. Using
pangomm I always get very thick fonts, while I want thin fonts. I
tried playing around with font weight etc, but this only has minimal
effect. I also played around with different fonts, but they all have
the same problem. Anyone any tips?

Cheers, Edwin

Example code:
#include <string>
#include <cairomm/context.h>
#include <cairomm/surface.h>

#include <pangomm/init.h>
#include <pangomm/context.h>
#include <pangomm/layout.h>

int main()
{
	Cairo::RefPtr<Cairo::ImageSurface> surface =
		Cairo::ImageSurface::create(Cairo::FORMAT_ARGB32, 600, 400);

	Cairo::RefPtr<Cairo::Context> cr = Cairo::Context::create(surface);
	cr->set_source_rgb(0.86, 0.85, 0.47);
	cr->paint();    // fill image with the color

	Pango::init();
	Glib::RefPtr<Pango::Layout> pangoLayout = Pango::Layout::create (cr);
	Pango::FontDescription pango_font = Pango::FontDescription("verdana 10");
	pango_font.set_weight( Pango::WEIGHT_ULTRALIGHT );
	pangoLayout->set_font_description( pango_font );

	cr->move_to(300,200);
	cr->set_source_rgb(0, 0, 0);
	pangoLayout->set_text("text");
	//pangoLayout->update_from_cairo_context(cr);  //gets cairo cursor position
	pangoLayout->add_to_cairo_context(cr);       //adds text to cairos
stack of stuff to be drawn
	cr->stroke();

	std::string filename = "image.png";
	surface->write_to_png(filename);
}
