DR ARRAY SCALE TO BASE (area; scaleArray; baseArray)

Parameter	Type		Description
area	Longint		4D Draw area
scaleArray	Numeric Array		Array of scale values
baseArray	Numeric Array		Array of base values

The command DR ARRAY SCALE TO BASE converts an array of scale values into an array of base values according to the ruler setup in area. Both arrays must be numeric (Integer, Longint, or Real) and can be the same array. When you use this command, you do not have to convert each array element individually.

After a call to DR ARRAY SCALE TO BASE, baseArray contains the same number of elements as scaleArray. This command is especially useful when working with DR POLYGON TO ARRAY, DR Array to polygon, DR ATTRIBUTE TO ARRAY, and DR ARRAY TO ATTRIBUTE.

The following example uses the arrays from the example for DR ARRAY BASE TO SCALE. It converts the arrays back to base units and then creates a new polygon with the values.

   DR ARRAY SCALE TO BASE (Area;ArrayH;ArrayH)
   DR ARRAY SCALE TO BASE (Area;ArrayV;ArrayV)
   $ID := DR Array to polygon (Area;ArrayH;ArrayV)

DR ARRAY BASE TO SCALE, DR GET RULER, DR SET RULER.
