GdkPixbuf
An object holding information about images in memory.
Object Hierarchy
Description
A GdkPixbuf is an object that holds information about a whole image (all the color values [red/green/blue/alpha] for every single pixel) in memory.
Pixbufs can be created by loading an image file via GdkPixbuf::new_from_file, by using a given GD image object as source (GdkPixbuf::new_from_gd) or just using the normal constructor, creating an empty image.
A GdkPixbuf itself just contains the information, it does not display it in any way. To display an image in your application, you most likely want to use a GtkImage which uses a GdkPixbuf as source.
Constructors
-- Creates an empty image with the desired size.GdkPixbuf::new_from_file (string filename);-- Creates a pixbuf based on an image file.GdkPixbuf::new_from_file_at_size (string filename, int width, int height);-- Load an image file and scales it to the given size.GdkPixbuf::new_from_xpm_data ( data);--GdkPixbuf::new_from_gd ( gd_image);-- Create a pixbuf based on a GD image object
Methods
