Values
| Name | Remarks |
|---|---|
| None | No compression is applied. |
| RLE | This compression method is fast, and works well for images with large flat areas but yields worse results for grainy images. |
| ZIPS | This compression method is similar to ZIP but compresses only one image row at a time. Lossless. |
| ZIP | Good compression quality for images with low amounts of noise. |
| PIZ | Good compression quality for grainy images. Lossless. |
| PXR24 | This format only stores 24 bits of the 32 bit data and has subsequently a significant loss of precision. |
| B44 | This compression method only applies to images stored in HALF color depth. |
| B44A | A modified version of B44. |
| DWAA | Lossy DCT-based compression for RGB channels. |
| DWAB | Similar to DWAA but goes in blocks of 256 scanlines instead of 32. |
| Max |
