Members
| Member name | Description |
|---|---|
| DEFLATE_RECOMENDED | The most optimised compression, with a good balance of speed and compression efficiency. Uses a faster deflate implementation with no compression scale. |
| ZIP_LEVEL0 | The data will be simply stored, with no change at all. Uses a slower deflate implementation with a compression scale. |
| ZIP_LEVEL1 | The fastest but least effective compression. Uses a slower deflate implementation with a compression scale. |
| ZIP_LEVEL2 | A little slower, but better, than level 1. Uses a slower deflate implementation with a compression scale. |
| ZIP_LEVEL3 | A little slower, but better, than level 2. Uses a slower deflate implementation with a compression scale. |
| ZIP_LEVEL4 | A little slower, but better, than level 3. Uses a slower deflate implementation with a compression scale. |
| ZIP_LEVEL5 | A little slower than level 4, but with better compression. Uses a slower deflate implementation with a compression scale. |
| ZIP_LEVEL6 | A little slower than level 5, but with better compression. Uses a slower deflate implementation with a compression scale. |
| ZIP_LEVEL7 | Better compression than level 6, but even slower. Uses a slower deflate implementation with a compression scale. |
| ZIP_LEVEL8 | Better compression than level 7, but even slower. Uses a slower deflate implementation with a compression scale. |
| ZIP_LEVEL9 | The “best” compression, where best means greatest reduction in size of the input data stream. This is also the slowest compression. Uses a slower deflate implementation with a compression scale. |
