Expand description
The types of compression allowed for a CHD V5 hunk.
Variants§
CompressionType0 = 0
The first compression codec specified in the header for this CHD.
CompressionType1 = 1
The second compression codec specified in the header for this CHD.
CompressionType2 = 2
The third compression codec specified in the header for this CHD.
CompressionType3 = 3
The fourth compression codec specified in the header for this CHD.
CompressionNone = 4
Uncompressed hunk.
CompressionSelf = 5
Copy from another hunk in this CHD.
CompressionParent = 6
Copy from another hunk in the parent CHD.
CompressionRleSmall = 7
Small-repetition Huffman RLE. Only used for map compression.
CompressionRleLarge = 8

CompressionSelf0 = 9
RLE Pseudo-codec for copy-from-self with 0-repetition. Only used for map compression.
CompressionSelf1 = 10
RLE Pseudo-codec for copy-from-self with 1-repetition. Only used for map compression.
CompressionParentSelf = 11
RLE Pseudo-codec for copy-from-parent with self-offset. Only used for map compression.
CompressionParent0 = 12
RLE Pseudo-codec for copy-from-parent for 1-repetition. Only used for map compression.
