Hierarchy

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

Overview

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
