It's a Perl-level subclass of \f(CW\*(C`Cairo::Context\*(C'\fR and the various functions below can be used as methods on it. .PP The methods can also be used on other \f(CW\*(C`Cairo::Context\*(C'\fR as plain functions. For example \f(CW\*(C`set_source_pixbuf\*(C'\fR can setup to draw from a \&\f(CW\*(C`Gtk2::Gdk::Pixbuf\*(C'\fR to any Cairo context, .PP .Vb 3 \& my $cr = Cairo::Context\->create ($surface); \& Gtk2::Gdk::Cairo::Context::set_source_pixbuf ($cr, $pixbuf, $x,$y); \& $cr\->paint; .Ve .SH METHODS .IX Header "METHODS" .SS "gdkcr = Gtk2::Gdk::Cairo::Context\->\fBcreate\fP ($drawable)" .IX Subsection "gdkcr = Gtk2::Gdk::Cairo::Context->create ($drawable)" .IP \(bu 4 \&\f(CW$drawable\fR (Gtk2::Gdk::Drawable) .ie n .SS "$gdkcr\->\fBrectangle\fP ($rectangle)" .el .SS "\f(CW$gdkcr\fP\->\fBrectangle\fP ($rectangle)" .IX Subsection "$gdkcr->rectangle ($rectangle)" .ie n .SS "$gdkcr\->\fBrectangle\fP ($x, $y, $width, $height)" .el .SS "\f(CW$gdkcr\fP\->\fBrectangle\fP ($x, \f(CW$y\fP, \f(CW$width\fP, \f(CW$height\fP)" .IX Subsection "$gdkcr->rectangle ($x, $y, $width, $height)" .ie n .SS "Gtk2::Gdk::Cairo::Context::rectangle ($anycr, $rectangle)" .el .SS "Gtk2::Gdk::Cairo::Context::rectangle ($anycr, \f(CW$rectangle\fP)" .IX Subsection "Gtk2::Gdk::Cairo::Context::rectangle ($anycr, $rectangle)" .IP \(bu 4 \&\f(CW$rectangle\fR (Gtk2::Gdk::Rectangle) .PP The 4\-argument x,y,width,height is the base Cairo::Context style.
