These functions convert relative addresses to absolute addresses

In:

data - data buffer

size - size of data

ip - current virtual Instruction Pinter (IP) value

state - state variable for x86 converter

level - compression level: 0 <= level <= 9, the default value for "level" is 5.
|
||||
|

dictSize - The dictionary size in bytes. The maximum value is
|

128 MB = (1 << 27) bytes for 32-bit version
|

1 GB = (1 << 30) bytes for 64-bit version
|
||||
The default value is 16 MB = (1 << 24) bytes, for level = 5.
|
||||
It's recommended to use the dictionary that is larger than 4 KB and
|
||||
that can be calculated as (1 << N) or (3 << N) sizes.
|

For better compression ratio dictSize must be >= inSize.

filterMode:

SZ_FILTER_NO - no Filter

SZ_FILTER_YES - x86 Filter

SZ_FILTER_AUTO - it tries both alternatives to select best.

Encoder will use 2 or 3 passes:

2 passes when FILTER_NO provides better compression.

3 passes when FILTER_YES provides better compression.

|

6: 32 MB 1 32
|
||||
7+: 64 MB 1 64
|
||||
|
||||
The default value for "level" is 5.
|
||||
|
||||
algo = 0 means fast method
|
||||
algo = 1 means normal method
|
||||
|
||||
dictSize - The dictionary size in bytes. The maximum value is
|
||||
128 MB = (1 << 27) bytes for 32-bit version
|
||||
1 GB = (1 << 30) bytes for 64-bit version
|
||||
The default value is 16 MB = (1 << 24) bytes.
|
||||
It's recommended to use the dictionary that is larger than 4 KB and
|
||||
that can be calculated as (1 << N) or (3 << N) sizes.
|
||||
|
||||
lc - The number of literal context bits (high bits of previous literal).
|
||||
It can be in the range from 0 to 8. The default value is 3.
|
||||
Sometimes lc=4 gives the gain for big files.
|
||||
|
||||
lp - The number of literal pos bits (low bits of current position for literals).
|
||||
It can be in the range from 0 to 4. The default value is 0.
|
||||
The lp switch is intended for periodical data when the period is equal to 2^lp.
|
||||
For example, for 32-bit (4 bytes) periodical data you can use lp=2. Often it's
|
||||
better to set lc=0, if you change lp switch.
|
||||
|
||||
pb - The number of pos bits (low bits of current position).
|
||||
It can be in the range from 0 to 4. The default value is 2.
|
||||
The pb switch is intended for periodical data when the period is equal 2^pb.
|
||||
|
||||
fb - Word size (the number of fast bytes).
|
||||
It can be in the range from 5 to 273. The default value is 32.
|
||||
Usually, a big number gives a little bit better compression ratio and
|
||||
slower compression process.
|
||||
|
||||
numThreads - The number of thereads. 1 or 2. The default value is 2.
|
||||
Fast mode (algo = 0) can use only 1 thread.
|
||||
|
||||
Out:
|
||||
destLen - processed output size
|

Returns:

SZ_OK - OK

SZ_ERROR_MEM - Memory allocation error
|

SZ_ERROR_PARAM - Incorrect paramater
