I'm currently trying to draw an RGB image onto the screen. My latest
approach is to load the image, create a pixmap, draw the image onto the
pixmap and then draw the pixmap onto a drawing_area. The problem is that
the program sigsevs at the gdk_draw_rgb_image call. This is the relevant
code:
gint configure_event(GtkWidget *widget, GdkEventConfigure *event)
{
if(gdkpixmap)
gdk_pixmap_unref(gdkpixmap);
gdk_pixmap_new(widget->window,
widget->allocation.width,
widget->allocation.height,
-1);
gdk_draw_rgb_image(gdkpixmap,
widget->style->fg_gc[0], <- Not clear about this
0,0,
piccy->width, piccy->height,
GDK_RGB_DITHER_NONE,
piccy->Image,
piccy->width);
g_print("here\n");
return TRUE;
}
Also, just after gtk_init() I call gdk_rgb_init(). Any help much
appreciated.
Cheers
Dave
