Enum PngCompressionLevel
Namespace: Aspose.Imaging.ImageOptions
Assembly: Aspose.Imaging.dll (25.7.0)
The png compression level enum.
public enum PngCompressionLevelFields
DeflateRecomended = 10
The most optimised compression, with a good balance of speed and compression efficiency. Uses a faster deflate implementation with no compression scale.
ZipLevel0 = 0
The data will be simply stored, with no change at all. Uses a slower deflate implementation with a compression scale.
ZipLevel1 = 1
The fastest but least effective compression. Uses a slower deflate implementation with a compression scale.
ZipLevel2 = 2
A little slower, but better, than level 1. Uses a slower deflate implementation with a compression scale.
ZipLevel3 = 3
A little slower, but better, than level 2. Uses a slower deflate implementation with a compression scale.
ZipLevel4 = 4
A little slower, but better, than level 3. Uses a slower deflate implementation with a compression scale.
ZipLevel5 = 5
A little slower than level 4, but with better compression. Uses a slower deflate implementation with a compression scale.
ZipLevel6 = 6
A little slower than level 5, but with better compression. Uses a slower deflate implementation with a compression scale.
ZipLevel7 = 7
Better compression than level 6, but even slower. Uses a slower deflate implementation with a compression scale.
ZipLevel8 = 8
Better compression than level 7, but even slower. Uses a slower deflate implementation with a compression scale.
ZipLevel9 = 9
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.
