[webkit-help] cannot create a snapshot of WebKitWebView

[avishkar gupta]

hi,


I have the following code which compiles and runs successfully,however no matter what uri I choose I always get the error “There was an error creating the snapshot”. I would please request you to point out the problem with this code.


Please note that in order to run this code you need to provide a uri argument to webkit_web_view_load_uri.


I would have not posted this here but I could not find any coding samples or additional documentation available on said topic, other than the API docs.


thanks.


#include <webkit2/webkit2.h>

snapshot_chain_cb(WebKitWebView *web_view,
      GAsyncResult* res,
      gpointer data)
{
 GError * err = NULL ;
 cairo_surface_t *surface = webkit_web_view_get_snapshot_finish(WEBKIT_WEB_VIEW(web_view),res,&err);
 if ( err )
 {
  printf("We have a problem.Specifically:%s\n",err->message);
 }
}
