Class GdkPixbuf.Pixbuf

Import line:	GdkPixbuf = imports.gi.GdkPixbuf;
GIR File:	GdkPixbuf-2.0.gir
C documentation:	GdkPixbuf
Class :	Pixbuf
Implements:	Gio.Icon
Extends:	GObject.Object

This is the main structure in the &gdk-pixbuf; library. It is
used to represent images. It contains information about the
image's pixel data, its color space, bits per sample, width and
height, and the rowstride (the number of bytes between the start of
one row and the start of the next).

Create a new GdkPixbuf containing a copy of src scaled to should be GDK_INTERP_NEAREST if you want maximum speed (but when scaling down GDK_INTERP_NEAREST is usually unusably ugly). The default interp_type should be GDK_INTERP_BILINEAR which offers reasonable quality and speed. You can scale a sub-portion of src by creating a sub-pixbuf pointing into src; see gdk_pixbuf_new_subpixbuf(). For more complicated scaling/compositing see gdk_pixbuf_scale() and gdk_pixbuf_composite(). allocated for it. Parameters: gint32 dest_width Required (not null) the width of destination image gint32 dest_height Required (not null) the height of destination image GdkPixbuf.InterpType interp_type Required (not null) the interpolation type for the transformation. Returns: GdkPixbuf.Pixbuf the new GdkPixbuf, or NULL if not enough memory could be	GdkPixbuf.Pixbuf
	to_string () : String Generates a textual representation of icon that can be used for serialization such as when passing icon to a different process or saving it to persistent storage. Generates a textual representation of icon that can be used for serialization such as when passing icon to a different process or saving it to persistent storage. Use g_icon_new_for_string() to get icon back from the returned string. The encoding of the returned string is proprietary to GIcon except in the following two cases If icon is a GFileIcon, the returned string is a native path (such as /path/to/my icon.png) without escaping if the GFile for icon is a native file. If the file is not native, the returned string is the result of g_file_get_uri() (such as sftp://path/to/my%%20icon.png). If icon is a GThemedIcon with exactly one name, the encoding is simply the name (such as network-server). be serialized. Use g_free() to free. Returns: String An allocated NUL-terminated UTF8 string or NULL if icon can't	Gio.Icon
