cls-precomp - for any version
This is a CLS library for Precomp that can be used as multithreads.
Tested on
Precomp 0.38, 0.40, 0.41, 0.42, 0.43, 0.44, 0.45, 0.46, 0.47, 0.48. (may work on future versions.
)
- User can select different detection methods (and other options).
- Detection methods,
1. Intense
2. Brute
Test Results on
Precomp 0.48 x32:
- -intense0 : 1.51 GB --> 2.35 GB
- -intense2 : 1.51 GB --> 2.63 GB
- -brute : 1.51 GB --> 2.64 GB
Old PrecompX(v1.0 and v2.0) uses -intense0.
You can get different compression ratio by changing the Chunk size and the Options.
Code:
Precomp v0.4.8 - options
-[option]:
c[lbn] Compression method to use, l = lzma2, b = bZip2, n = none <l>
lm[amount] Set maximal LZMA memory in MiB <1024>
lt[count] Set LZMA thread count <auto-detect: 4>
lf[+-][xpiatsd] Set LZMA filters (up to 3 of them can be combined) <none>
lf+[xpiatsd] = enable these filters, lf- = disable all
X = x86, P = PowerPC, I = IA-64, A = ARM, T = ARM-Thumb
S = SPARC, D = delta (must be followed by distance 1..256)
llc[bits] Set LZMA literal context bits <3>
llp[bits] Set LZMA literal position bits <0>
The sum of lc and lp must be inside 0..4
lpb[bits] Set LZMA position bits, must be inside 0..4 <2>
n[lbn] Convert a PCF file to this compression (same as above) <off>
d[depth] Set maximal recursion depth <10>
pfmeta[amount] Split deflate streams into meta blocks of this size in KiB <2048>
pfverify Force preflate to verify its generated reconstruction data
intense Detect raw zLib headers, too. Slower and more sensitive <off>
brute Brute force zLib detection. VERY Slow and most sensitive <off>
t[+-][pzgnfjsmb3] Compression type switch <all enabled>
t+ = enable these types only, t- = enable all types except these
P = PDF, Z = ZIP, G = GZip, N = PNG, F = GIF, J = JPG
S = SWF, M = MIME Base64, B = bZip2, 3 = MP3
f Fast mode, use first found compression lvl for all streams <off>
i[pos] Ignore stream at input file position [pos] <none>
s[size] Set minimal identical byte size to [size] <4 (64 intense mode)>
pdfbmp[+-] Wrap a BMP header around PDF images <off>
progonly[+-] Recompress progressive JPGs only (useful for PAQ) <off>
mjpeg[+-] Insert huffman table for MJPEG recompression <on>
You can use an optional number following -intense and -brute to set a
limit for how deep in recursion they should be used. E.g. -intense0 means
that intense mode will be used but not in recursion, -intense2 that only
streams up to recursion depth 2 will be treated intense (3 or higher in
this case won't). Using a sensible setting here can save you some time.
