invoke
long invoke(long data, int data_len, long out_len, int quality)
Compresses a block of data using Zlib compression.The returned data will be freed with
MemoryUtil.memFree(java.nio.Buffer)
so it must be heap allocated withMemoryUtil.memAlloc(int)
.- Parameters:
data
- the data to compressdata_len
- the data length, in bytesout_len
- returns the compressed data length, in bytesquality
- the compression quality to use- Returns:
- the compressed data
