Enum png::Compression
source · pub enum Compression {
Default,
Fast,
Best,
Huffman,
Rle,
}
Expand description
The type and strength of applied compression.
Variants§
Default
Default level
Fast
Fast minimal compression
Best
Higher compression level
Best in this context isn’t actually the highest possible level
the encoder can do, but is meant to emulate the Best
setting in the Flate2
library.
Huffman
👎Deprecated since 0.17.6: use one of the other compression levels instead, such as ‘fast’
Rle
👎Deprecated since 0.17.6: use one of the other compression levels instead, such as ‘fast’
