void BASE_IMPEXP mrpt::compress::zip::compress | ( | void * | inData, |
size_t | inDataSize, | ||
std::vector< unsigned char > & | outData | ||
) |
Compress an array of bytes into another one.

size_t | inDataSize, | ||
void * | outData, | ||
size_t | outDataBufferSize, | ||

bool BASE_IMPEXP mrpt::compress::zip::decompress_gz_data_block | ( | const vector_byte & | in_gz_data, |
vector_byte & | out_data | ||
) |
Decompress an array of bytes storing a gz-compressed stream of data into a memory buffer.
If the input data is not recognized as a .gz file, the output data will be an exact copy of the input.
bool BASE_IMPEXP 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.
