I am retrieving jpg's from file and displaying them on any one of four
monitors on the computer. I run the program 4 times (one time for each
monitor, modified to output its results to the appropriate monitor).
The problem is it is very processor intesive, running about 100% for all
4 programs running at the same time. I had initially read from disk to
load each image into the window, to update say a radar loop. I want to
load the images to memory and just cycle through them but am running
into problems with what path to take to do this. What functions, or
method should I use to do this so its as efficient as possible? Here is
the part of the function that does the loading of image and update to
window.
/*-----------------------------------------------------------------------------------------*/
//cb_timeout Function
static gint cb_timeout(gpointer screen)
{
struct window_data *display = (struct window_data *) screen;
//For Development progress/error detection
//g_print("In Timeout %d\n", display->counter);
if (display->counter != 11)
display->counter++;
else if (display->counter == 11)
display->counter = 0;
//Destroy current Image Widget and Re-assign it
gtk_widget_destroy(display->image);
display->image =
gtk_image_new_from_file(display->image_name[display->counter]->str);
//Re-Pack Box with Image and Refresh the image in the window
gtk_box_pack_start(GTK_BOX(display->box), display->image, FALSE,
FALSE, 0);
gtk_widget_realize(display->image);
gtk_widget_show(display->image);
gtk_window_move(GTK_WINDOW(display->window), 0, 0);
gtk_window_fullscreen(GTK_WINDOW(display->window));
return TRUE;
}
/*-----------------------------------------------------------------------------------------*/
Thanks,
Matt
