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

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

Ikonikos is an image manager that, instead of working with files and directories, works with tags. With them, you can create powerful search filters. It's also very portable, easy to use, and fast.
