Define Documentation

#define SVN_DELTA_COMPRESSION_LEVEL_DEFAULT   5

This is the default compression level we pass to zlib. It should be between 0 and 9, with higher numbers resulting in better compression rates but slower operation.

Since:

New in 1.7.

Definition at line 70 of file svn_delta.h.

#define SVN_DELTA_COMPRESSION_LEVEL_MAX   9

This is the maximum compression level we can pass to zlib.

Since:

New in 1.7.

Definition at line 62 of file svn_delta.h.

#define SVN_DELTA_COMPRESSION_LEVEL_NONE   0

This compression level effectively disables data compression. However, the data pre-processing costs may still not be zero.

Since:

New in 1.7.

Definition at line 56 of file svn_delta.h.
