Help Using Gdk_image

[Michael Noonan <mick_n_10 yahoo ie>]

Hello,

I'm new to using gtk and would really appreciate it if
anybody could help me. 

I'm trying to display an image on the screen thats
created from individual pixel information. I create
the image and then set the indivisual pixels. Then I
try to display the image but I keep getting errors
when I try to execute. 

Am I going about this the wrong way! I've attached the
code below.

Thanks in advance.
Mike

#include <stdio.h>
#include <gtk/gtk.h>
#include <gdk/gdktypes.h>
using namespace std;

int main( int argc, char *argv[])
{
        GtkWidget *window;
        GtkWidget *canvas;
        GdkVisual *visual;
        GdkImage *image;
        GdkGC *gc;
        
        int i, j;
        unsigned char frame_data[128][64];
                
        window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
        
        gtk_widget_set_size_request(GTK_WIDGET(window), 1024,
768);
        
        g_signal_connect(G_OBJECT(window), "destroy",
G_CALLBACK(gtk_main_quit), NULL);
        
        visual = gdk_visual_get_system();
        image = gdk_image_new( GDK_IMAGE_FASTEST, visual, 64,
128 );
        
        gc = gdk_gc_new( GTK_WIDGET( window )->window );
        
        canvas = gtk_drawing_area_new();
        gtk_container_add( GTK_CONTAINER( window ), canvas);
        gtk_widget_show(canvas);
        
        //set the individual pixels
        for( i = 0; i < 128; i++ )
        {
                for( j = 0; j < 64; j++ )
                { 
                        gdk_image_put_pixel( image, i, j, data[i][j] );
                }
        }
                
        gdk_draw_image( GTK_WIDGET( canvas )->window, gc,
image, 0,0,0,0, 64, 128);
        
        gtk_widget_show(window);
        
        gtk_main();
}
