Function Documentation

void MRPTDLLIMPEXP mrpt::compress::zip::compress ( const std::vector< unsigned char > &  inData,
CStream &  out 
)

Compress an array of bytes and write the result into a stream.

void MRPTDLLIMPEXP mrpt::compress::zip::compress ( void *  inData,
size_t  inDataSize,
CStream &  out 
)

Compress an array of bytes and write the result into a stream.

void MRPTDLLIMPEXP mrpt::compress::zip::compress ( const std::vector< unsigned char > &  inData,
std::vector< unsigned char > &  outData 
)

Compress an array of bytes into another one.

void MRPTDLLIMPEXP mrpt::compress::zip::compress ( void *  inData,
size_t  inDataSize,
std::vector< unsigned char > &  outData 
)

Compress an array of bytes into another one.

bool MRPTDLLIMPEXP mrpt::compress::zip::compress_gz_file ( const std::string &  file_path,
const vector_byte &  buffer,
const int  compress_level = 9 
)

Compress a memory buffer into a gzip file (xxxx.gz).

compress_level: 0=no compression, 1=best speed, 9=maximum

Returns:
true on success, false on error.

void MRPTDLLIMPEXP mrpt::compress::zip::decompress ( CStream &  inStream,
size_t  inDataSize,
void *  outData,
size_t  outDataBufferSize,
size_t &  outDataActualSize 
)

Decompress an array of bytes into another one

Exceptions:
std::exception If the apriori estimated decompressed size is not enought.

void MRPTDLLIMPEXP mrpt::compress::zip::decompress ( void *  inData,
size_t  inDataSize,
void *  outData,
size_t  outDataBufferSize,
size_t &  outDataActualSize 
)

Decompress an array of bytes into another one

Exceptions:
std::exception If the apriori estimated decompressed size is not enought.

void MRPTDLLIMPEXP mrpt::compress::zip::decompress ( void *  inData,
size_t  inDataSize,
std::vector< unsigned char > &  outData,
size_t  outDataEstimatedSize 
)

Decompress an array of bytes into another one

Exceptions:
std::exception If the apriori estimated decompressed size is not enought.

bool MRPTDLLIMPEXP mrpt::compress::zip::decompress_gz_file ( const std::string &  file_path,
vector_byte &  buffer 
)

Decompress a gzip file (xxxx.gz) into a memory buffer.

If the file is not a .gz file, it just read the whole file unmodified.

Returns:
true on success, false on error.
