Hello, Zahra.
You can use GdkPixbufLoader for retrieve pixbuf from raw data.
Code example:
GdkPixbufLoader *loader = gdk_pixbuf_loader_new();
gdk_pixbuf_loader_write(loader, buffer, buffer_size, NULL);
gdk_pixbuf_loader_close(loader, NULL);
GdkPixbuf* pixbuf =
gdk_pixbuf_copy(gdk_pixbuf_loader_get_pixbuf(loader));
g_object_unref(loader);
Now 'pixbuf' contains image, previously stored in 'buffer'.
If you want to do more complex things, than simple restoring pixbuf
from buffer, you may read GdkPixbufLoader description
