A Somewhat Complete Listing of the SHP File Codes
,0
end of the line
0,0
lift the pen after multiple up or down pen sequences
1,8
make one move with in pen down mode
1,9
make a series of moves in pen down mode
2,8
make one move with the pen up
4,
multiply by
3,
divide by
5,
push position on to stack (remember position of pen)
6,
pop position off stack (return to previously remembered position)
7,
load a character at this position (ex. 7,65 will draw the character defined as code 65 at this location)
,8
continue in pen up mode
This listing uses the term pen to refer to the concept of moving
the cursor around as the character is created. This analogy is similar
to the method a pen plotter works by placing a pen on the paper and
moving and/or lifting the pen to draw the character. Refer to the tutorial
on creating fonts for more information.
The multiplication and divide codes can be used to get around the limits
of the SHP file with regard to the need for whole number coordinates.
The character loading function can be used to create compound letter
codes. For example a centerline character might be a C with an L imposed
over it. If these characters are defined in the SHP file you could use
the codes for both C and L to create this symbol rather than redrawing
this new shape.
