HALCON的图形窗口是极为常用的一个窗口，
在上面我们可以显示图像，显示区域，显示代码每一步的执行效果等等。
Halcon中提供众多函数针对此窗口的个性化设置。
比如设置线宽，设置显示颜色类型颜色种类，区域显示形状等等。
这节课我们也一样在halcon当前运行这此函数，查看函数效果与功能。

这些函数为以下这些
set_draw get_draw  set_shape  get_shape  query_shape  set_icon
get_icon  set_insert  get_insert  query_insert  set_line_width
get_line_width query_line_width  set_line_style
get_line_style  set_paint
get_paint  query_paint  set_part  get_part  set_part_style get_part_style
set_window_param  get_window_para  set_colored  query_colored
set_color  query_color  query_all_colors
set_rgb  get_rgb  get_rgba set_rgba  set_hsi
get_hsi  set_gray  query_gray  color_string_to_rgb
convert_coordinates_window_to_image
convert_coordinates_image_to_window
