Custom RLE compression

[qbasic]

Hi.

I have a troubles with some RLE algo. I want to find it's name, if it is public well-known algorithm, or I need compression for it.

Here is reconstructed sources of decompression routine, I can attach samples too.

Compressed data haven't any headers, just RLE data itself.

May be somebosy meeted it.

yeah upload some samples, I will scan them with quickbms to know if the compression algorithm is recognized (it's easier than looking at many source code files).

maybe it's just lzo, that "17" sounds familiar

Hm.. Can you tell me, how to recognize compression algo?

[aluigi]

some can be guessed or you can give just an opinion by watching the data with a hex editor (like zlib).

others can be scanned and then you must check the resulted decompressed files to know if you recognize data with a sense.

anyway if you are interested in quickbms and the comtype scanner:

Tyvm, its algo # 8.

COMP_LZO1X, so yes I guessed it correctly :)
