nx |
The tile is devided into this number in x (E-W) direction. |
ny |
The tile is devided into this number in y (N-S) direction.
Normally both numbers are equal (1, 2, 4, 8). |
xwid |
x size of one sub tile (total size is nx*xwid). |
ywid |
y size of one subtile |
xofs |
x offset for the left lower corner (south west) |
yofs |
y offset for the left lower corner. These values are usually the
negative number of half of the total tile size. |
bxo |
bitmap pixel offset in x direction, usually 0 |
byo |
bitmap pixel offset in y direction, usually 0 |
flg |
flags, pupose unknown, normally 1 |
xbpg |
number of bitmaps per grid in x direction. Due to the binary
instruction format only values from 0.0625 (=1/16) to 15.9375
(=16 - 1/16) are possible. SCASM does not check these limits. |
ybpg |
number of bitmaps per grid in y direction.
Note: it seems that CFS becomes confused if xbpb and ybpg are not equal. |
<list..> |
The list of the elevation points. The fist point is in the south west.
Only integer are numbers allowed. The number of points is:
(nx + 1) * (ny + 1)
Example, for nx = 2 and ny = 2
(2 + 1) * (2 + 1) = 3 * 3 = 9 |
