gdk_pixbuf_render_to_drawable_alpha & segault...

[jeff <jeff hype52 com>]

hi, you'll have to excuse my stupidity on these issues. this is my first attempt at coding anything for 
linux/x (and using gtk ;/)

anywho im trying to display transparent png's (actually one on top of another) in a fixed container.

i originally used gdk_pixbuf_render_pixmap_and_mask() but id like to use true alpha and not the alpha 
tolerence.. (is this function avail w/out that?)

gdk_pixbuf_render_to_drawable_alpha causes a segfault :{ my code:

(animation bits here just for future implementation, also offset is just a global var i used for offsetting 
the images)

void setup_pixmap (char *filename, GtkWidget *fixed)
{
        GtkWidget *pix;
        GdkPixbufAnimation *anim;
        GdkPixbuf *unanim;

        if (filename == 0)
                return;
        
        anim = gdk_pixbuf_animation_new_from_file(filename, 0);
        if (gdk_pixbuf_animation_is_static_image(anim)){
                unanim = gdk_pixbuf_animation_get_static_image(anim);

                gdk_pixbuf_render_to_drawable_alpha (unanim, pix->window, 0, 0, 0, 0, -1, -1, 
GDK_PIXBUF_ALPHA_FULL, 0, GDK_RGB_DITHER_NONE, 0, 0);

                gdk_pixbuf_unref(unanim);
        }else{
                pix = gtk_image_new_from_animation(anim);
                gdk_pixbuf_animation_unref(anim);       
        }
                gtk_fixed_put (GTK_FIXED (fixed), pix, offset*30, offset*30);
                gtk_widget_show(pix);

        offset++;
}
