A Strater Lithographic Line File [.LLF] is an exchange format for lithology indent lines scheme indent line styles. You can import line styles into the line indent lines palette. Once you have modified the palette, you can save the palette as a Strater Lithographic Line File [.LLF] for use on other computers or by colleagues. The [.LLF] file format is based on the Atlas Boundary [.BNA] format.
The Strater Lithographic Line File [.LLF] is an ASCII file with the following format:
"Name 1", "Second Name", Vertices
x1,y1
x2,y2
...
xn,yn
"Name 2", "Second Name", Vertices
x1,y1
x2,y2
...
xn,yn
Where:
The Name is the indent line style name.
Second Name is a field that is not used by Strater currently. You must include an empty field here. The empty field is surrounded by double quotes with no spaces.
Vertices is an integer that identifies the number of coordinate pairs to follow. This value is always preceded by the negative sign.
Following the Vertices are the actual X,Y coordinate pairs that make up the line. These can be integers or real numbers, and are stored one pair per line.
Example
The following is an example of an [.LLF] file that contains three required indent line styles (Straight, Slope Down, and Slope Up) and an optional indent line style ( Zig).
"Straight","",-2
500.000000,0.000000
500.000000,1000.000000
"Slope Down","",-2
0.000000,0.000000
1000.000000,1000.000000
"Slope Up","",-2
1000.000000,0.000000
0.000000,1000.000000
" Zig","",-5
0.000000,0.000000
985.981361,206.521713
355.140250,572.463812
1000.000000,836.956575
443.925313,1000.000000
Note that you cannot change the first three line styles (Straight, Slope Down, and Slope Up).
The coordinate range must be zero to 1000.
The y1 value must be zero.
The yn value must be 1000.
The X values must be between zero and 1000.
The coordinates cannot be negative.
