Hi!
 here is the part of the code I want to use to change the settings,
but they are still unchangeable. Is there anything wrong?

    valor2=Xo;
 
 estat=sane_control_option(gestor,22,SANE_ACTION_SET_VALUE,&valor2,valor);
    printf("%s: ",sane_strstatus(estat));
    valor2=Yo;
 
 estat=sane_control_option(gestor,23,SANE_ACTION_SET_VALUE,&valor2,valor);
    printf("%s: ",sane_strstatus(estat));
    valor2=Xo+WIDTH;
 
 estat=sane_control_option(gestor,24,SANE_ACTION_SET_VALUE,&valor2,valor);
    printf("%s: ",sane_strstatus(estat));
    valor2=Yo+HEIGHT;
 
 estat=sane_control_option(gestor,25,SANE_ACTION_SET_VALUE,&valor2,valor);
    printf("%s\n",sane_strstatus(estat));

What should I write to make the changes permanent? I need to change
the dimensions of what is scanned, but I don't know how to do it.

are you calling sane_get_parameters() after you have changed the options?
