The line pattern codes are:
• 0 − solid
• 16 − dashed
• 32 − dotted
• 48 − dot dash
• 64 − dot dot dash
The line thickness and line pattern codes can be combined using arithmetic addition or bit−wise OR.
POLYLINE (type 2):
8 BYTES HEADER
16 bytes Normalized coordinate rectangle of the area around polyline
4 bytes Line type (0=default)
4 bytes Red/Green/Blue color code of lines
4 bytes N = number of co−ordinates (should be 2 or more)
N*8 bytes x/y−coordinates of the poly−line
NOTE: The line type field can contain the same codes as in the LINE (type 1) records.
WARNING−ICON (type 3):

(INcluding zero−termination)
1 byte M = length of the name of the message to be sent to
the callback window (INcluding zero−termination)
1 byte L = length of the full filename of the icon to display
(INcluding zero−termination)
1 byte K = length of the full filename of the bitmap mask for
the icon (INcluding zero−termination)
W bytes Zero−terminated name of the callback window
M bytes Zero−terminated name of the message to be sent to the
callback window
L bytes Zero−terminated filename of a .BMP file (a 48x48,
16−color or 256−color bitmap to be used as icon)
K bytes Zero−terminated filename of a .BMP file (a 48x48
monochrome bitmap to be used as mask)
