Lucene Image REtrieval 0.7 (Default branch)
The LIRE (Lucene Image REtrieval) library provides a simple way to create a Lucene index of image features for content-based image retrieval (CBIR), which allows searching for similar images. The used features are taken from the MPEG-7 standard: ScalableColor, ColorLayout, and EdgeHistogram. Furthermore, methods for searching the index are provided. License: GNU General Public License (GPL)Changes:
This is a major release. It fixes a lot of bugsand introduces several new features including anew descriptor, a simplified way to usedescriptors by introducing new generic searchersand indexers, as well as a generalized interfacefor image descriptors. There are also severalimprovements in indexing and search speed.Furthermore, retrieval performance was optimizedbased on the Wang 1000 data set. All new featureshave also found their way into LireDemo.Image

gtk2::gdk::image

Gtk2::Gdk::Image(3pm)					User Contributed Perl Documentation				     Gtk2::Gdk::Image(3pm)

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.

HIERARCHY

	 Glib::Object
	 +----Gtk2::Gdk::Image

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'
