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
