Gtk2::Gdk::Cairo::Context(3)

NAME
Gtk2::Gdk::Cairo::Context

HIERARCHY
    Cairo::Context
    +---- Gtk2::Gdk::Cairo::Context   (Perl subclass)

DESCRIPTION
This is some inter-operation between Cairo (see Cairo) and Gdk things.

A "Gtk2::Gdk::Cairo::Context" lets Cairo draw on a Gdk drawable (window or pixmap). It's a Perl-level subclass of "Cairo::Context" and the various functions below can be used as methods on it.

The methods can also be used on other "Cairo::Context" as plain functions. For example "set_source_pixbuf" can setup to draw from a "Gtk2::Gdk::Pixbuf" to any Cairo context,

    my $cr = Cairo::Context->create ($surface);
    Gtk2::Gdk::Cairo::Context::set_source_pixbuf ($cr, $pixbuf, $x,$y);
    $cr->paint;

METHODS

  gdkcr = Gtk2::Gdk::Cairo::Context->create ($drawable)

•   $drawable (Gtk2::Gdk::Drawable)

  $gdkcr->rectangle ($rectangle)

  $gdkcr->rectangle ($x, $y, $width, $height)

  Gtk2::Gdk::Cairo::Context::rectangle ($anycr, $rectangle)

•   $rectangle (Gtk2::Gdk::Rectangle)

The 4-argument x,y,width,height is the base Cairo::Context style. This extends to also take a "Gtk2::Gdk::Rectangle".

  $gdkcr->region ($region)

  Gtk2::Gdk::Cairo::Context::region ($anycr, $region)

•   $region (Gtk2::Gdk::Region)

  $gdkcr->reset_clip ($drawable)

  Gtk2::Gdk::Cairo::Context::reset_clip ($anycr, $drawable)

•   $drawable (Gtk2::Gdk::Drawable)

Since: gtk+ 2.18

  $gdkcr->set_source_color ($color)

  Gtk2::Gdk::Cairo::Context::set_source_color ($anycr, $color)

•   $color (Gtk2::Gdk::Color)

  $gdkcr->set_source_pixbuf ($pixbuf, $pixbuf_x, $pixbuf_y)

  Gtk2::Gdk::Cairo::Context::set_source_pixbuf ($anycr, $pixbuf, $pixbuf_x, $pixbuf_y)

•   $pixbuf (Gtk2::Gdk::Pixbuf)

•   $pixbuf_x (double)

•   $pixbuf_y (double)

  $gdkcr->set_source_pixmap ($pixmap, $pixmap_x, $pixmap_y)

  Gtk2::Gdk::Cairo::Context::set_source_pixmap ($anycr, $pixmap, $pixmap_x, $pixmap_y)

•   $pixmap (Gtk2::Gdk::Pixmap)

•   $pixmap_x (double)

•   $pixmap_y (double)

Since: gtk+ 2.10
