Script for DRAW option in LatLon vs inches on virtual screen

[Alfredo Ruiz-Barradas]

Aloha,

this is what I use to make a box; for instance, over central US:


*
raya=pintaraya(260,35,260,45,4,1,4)
raya=pintaraya(270,35,270,45,4,1,4)
raya=pintaraya(260,35,270,35,4,1,4)
raya=pintaraya(260,45,270,45,4,1,4)
*


function pintaraya(lon1,lat1,lon2,lat2,col,sty,thic)
*This function is good for drawing a line
*from (lon1,lat1) to (lon2,lat2) with color "col",
*style "sty" and thickness "thic".
*
'q w2xy 'lon1' 'lat1
say result
x1 = subwrd(result,3)
y1 = subwrd(result,6)
'q w2xy 'lon2' 'lat2
say result
x2 = subwrd(result,3)
y2 = subwrd(result,6)
'set line 'col' 'sty' 'thic
'draw line 'x1' 'y1' 'x2' 'y2
return

Hope this helps,

Alfredo
