C1.Zip.ZLib.ZStream.deflateInit
deflateInit Method
deflateInit(int)
Initializes the internal stream state for compression.
Declaration
public int deflateInit(int level)Parameters
| Type | Name | Description |
|---|---|---|
| int | level | Compression level between zero and nine (0-9). |
Returns
| Type | Description |
|---|---|
| int | Zero on success, an error code on failure. |
Remarks
Compression level 1 gives best speed, 9 gives best compression.
Compression level zero gives no compression at all (the input data is simply copied a block at a time).
The default compression level is 6, which provides a compromise between speed and compression.
deflateInit(int, int)

| Type | Name | Description |
|---|---|---|
| int | level | Compression level between zero and nine (0-9). |
| int | bits | Size of the LZ77 sliding compression window in bits (the default value is 15 bits). |
Returns
| Type | Description |
|---|---|
| int | Zero on success, an error code on failure. |
Remarks
Compression level 1 gives best speed, 9 gives best compression.
Compression level zero gives no compression at all (the input data is simply copied a block at a time).
