Hi,
I'm trying to draw circles on the map when there is no nmea data (using file as a source of vehicle). I succeeded to draw the vehicle position by calling "navit_vehicle_draw(this_, nv, NULL);" at "navit.c::navit_vehicle_update_position()" but I would like to draw additional points.
It seems that I miss a certain initialization that does not occur on offline mode (when there is no nmea data).
What am I missing?
Bellow is more details of the code I added.
Can you please help.
Thanks,
Sarit.
Code:
navit.c::navit_vehicle_update_position(struct navit *this_, struct navit_vehicle *nv)
....
transform(this_->trans_cursor, pro, &(this_->draw_route_circles.p1)/*p1_coord*/, &p_1, 1, 0, 0, NULL);
transform(this_->trans_cursor, pro, &(this_->draw_route_circles.pi)/*pi_coord*/, &p_i, 1, 0, 0, NULL);
transform(this_->trans_cursor, pro, &(this_->draw_route_circles.pi1)/*pi1_coord*/, &p_i1, 1, 0, 0, NULL);
dbg(lvl_error, "p_1(%d, %d), p_i(%d, %d), p_i1(%d, %d)",
p_1.x, p_1.y,
p_i.x, p_i.y,
p_i1.x, p_i1.y);
//graphics_draw_mode(this_->gra, draw_mode_begin);
graphics_draw_circle(this_->gra, this_->draw_route_circles.osd_color_pink, &p_1, this_->draw_route_circles.width);
graphics_draw_circle(this_->gra, this_->draw_route_circles.osd_color_red, &p_i, this_->draw_route_circles.width);
graphics_draw_circle(this_->gra, this_->draw_route_circles.osd_color_blue, &p_i1, this_->draw_route_circles.width);
graphics_draw_mode(this_->gra, draw_mode_end);[/code]
