   Hi George,

   Good questions! To go beyond the simple white background that you get with text_box_blanking='on' you need to use the Annotation View, described a bit here: https://confluence.ecmwf.int/display/METV/Layout+in+Metview

   Here is some Python code that uses it the way you want:

   text = mv.mtext(
       text_lines          = ["Hello world", "How are you?"],
       text_colour         = "black",
       text_font_size      = 0.5,
       text_mode           = "positional",
       text_justification  = "left"
       )
   
   gview = mv.geoview()
   
   geo_page = mv.plot_page(view = gview)
   
   annotation_view = mv.annotationview(
       #subpage_background_colour = "peach"
       subpage_background_colour = "RGBA(1, 0.5, 0.5, 0.5)"
       )
   
   text_page = mv.plot_page(
       top    = 40, # % of main page from top-left
       bottom = 50,
       left   = 30,
       right  = 55,
       view   = annotation_view
       )
   
   dw = mv.plot_superpage(pages = [geo_page,text_page])
   
   mv.plot(dw[0], data, dw[1], text)
   

   

   Unfortunately we do not support the gaps in isolines required for your second question, but blanking of labels is on, as long as you don't turn off contour_label_blanking.
   

   I hope this helps a little!

   Iain
