NAME

       Gtk2::Gdk::Image - wrapper for GdkImage

DESCRIPTION

       A "Gtk2::Gdk::Image" is a 2-D array of pixel values in client-side memory.  It can optionally use shared memory with the X server for fast
       copying to or from a window or pixmap.

       If you're thinking of using this then look at "Gtk2::Gdk::Pixbuf" first.  GdkPixbuf has many more features, in particular file read and
       write (PNG, JPEG, etc).	But a GdkImage lets you work directly in pixel values instead of expanding to RGB components.

       See Gtk2::Gdk::Drawable for "draw_image", "get_image" and "copy_to_image" methods to draw or fetch images to or from a window or pixmap.

       The various "get" methods are Gtk 2.22 style.  For previous versions they're direct field access.

METHODS

   image or undef = Gtk2::Gdk::Image->new ($type, $visual, $width, $height)
       o   $type (Gtk2::Gdk::ImageType)

       o   $visual (Gtk2::Gdk::Visual)

       o   $width (integer)

       o   $height (integer)

   integer = $image->get_bits_per_pixel
   byteorder = $image->get_byte_order
   integer = $image->get_bytes_per_line
   integer = $image->get_bytes_per_pixel
   colormap = $image->get_colormap
   $image->set_colormap ($colormap)
       o   $colormap (Gtk2::Gdk::Colormap)

   integer = $image->get_depth
   integer = $image->get_height
   imagetype = $image->get_image_type
   unsigned = $image->get_pixel ($x, $y)
       o   $x (integer)

       o   $y (integer)

   string = $image->get_pixels()
       Return a copy of the raw pixel data memory from $image.	This is "bytes_per_line * height" many bytes.

   $image->put_pixel ($x, $y, $pixel)
       o   $x (integer)

       o   $y (integer)

       o   $pixel (unsigned)

   visual = $image->get_visual
   integer = $image->get_width
ENUMS AND FLAGS

   enum Gtk2::Gdk::ByteOrder
       o   'lsb-first' / 'GDK_LSB_FIRST'

       o   'msb-first' / 'GDK_MSB_FIRST'

   enum Gtk2::Gdk::ImageType
       o   'normal' / 'GDK_IMAGE_NORMAL'

       o   'shared' / 'GDK_IMAGE_SHARED'

       o   'fastest' / 'GDK_IMAGE_FASTEST'
