The program 3DField can overlay a contour map on bitmap base map. One
can generate a list of files from which to choose a background. Base map can be
attached with contour map and scaled together.
The Objects | Base Map menu
opens the dialog.
The Add button adds a file in the list. The
list can contain positions in the same file, but at other attachment to a
contour map. The Delete button
removes a selected line from the list. The Visible box shows
or hides
background image on a map. Set as Default automatically places the
selected image on
a new map. Rename gives a position a new name.
The background can be stretched to a full window, placed at the center
or adhered to two coordinate points with the Assigning Coordinates button.
To attach the base map to the points, please, follow the
next step:
1. Press the Assigning Coordinates button
2. Double-click (or to enter manually) the first point's location (x1,
y1) in pixels. Enter the coordinates (X1, Y1)
for this location in units relative to the data points. OK
3. Double-click (or to enter manually) the second point's location (x2,
y2) in pixels. Enter the coordinates (X2, Y2)
for this location in units relative to the data points. OK
Check the Foreground and Transparent
boxes to move the base map over the color fill contour.
