Jazz Jackrabbit 2 Online

-----------------------------------------------
Jazz Jackrabbit level tiles importer\exporter
-----------------------------------------------

---------------
Usage:
---------------

EXPORTER:
-The directory must contain "pal.000", "ten.000" and a block file to read
from. No files will be overwritten; the JAZZ directory is the best place

-Enter the name of the block file you wish to extract

-Data will be exported as an 8-bit bitmap


IMPORTER
-The directory must contain a bitmap to r from. No files should be
overwritten

-Enter the name of the tile bitmap to read from, and the names of the two
background bitmaps. A BLOCKS.053 file will be created


---------------------------------
Notes:
---------------------------------
The last line of both background bitmaps is not displayed, the first line
is repeated twice instead. This becomes obvious in most cases.

The two background images can be any size, it is the palette that is
transcripted. I just like the look of 32x356 bitmaps.

Jazz likes multiples of 60 tiles (120, 180, 240 etc..) Anything different
from a bitmap of n x 6 rows of 10 tiles each may cause big troubble. Jazz
level masks work for 255 tiles, the most you can have



---------------------------------
Block format:
---------------------------------
Size of RLE block [Two bytes]
RLE block [Compressed palette 1 used for tiles]
Size of RLE block [Two bytes]
RLE block [Compressed palette 2 background sky 1]
Size of RLE block [Two bytes]
RLE block [Compressed palette 3 background sky 2]
Blocks [4 of these, variable size]

- 'FULL' BLOCK: (Contains 60 tiles)
'ok' [Two byte long string signalling that up to 60 tile blocks will
follow]

-TILES: [Each one level tile]
Size of RLE block [Two bytes]
RLE block [Compressed 32x32 tile]

- 'EMPTY' BLOCK: (Contains no data, these are thus at the end of the file)
