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.

o $drawable (Gtk2::Gdk::Drawable or undef) may be undef if $colormap is given
o $colormap (Gtk2::Gdk::Colormap or undef) GdkColormap to use for the new image; may be undef if $drawable is given.

o $transparent_color (Gtk2::Gdk::Color or undef) color of pixels that are transparent in the input file. if undef, a default is used.
o ... (list) of strings, xpm data
Create a pixmap from the provided xpm data, using a specific colormap. See "create_from_xpm_d".

($pixmap, $mask) = Gtk2::Gdk::Pixmap->create_from_xpm_d ($drawable, $transparent_color, @xpm_data)
o $drawable (Gtk2::Gdk::Drawable) used to determine the colormap and visual of the image.
o $transparent_color (Gtk2::Gdk::Color or undef) color of pixels that are transparent in the input file. if undef, a default is used.
o ... (list) of strings, xpm data
