Enum `CompressionType`

#[non_exhaustive]
pub enum CompressionType

DEFLATE compression level of a PNG encoder. The default setting is Fast.

Variants

Default: Default compression level
Fast: Fast, minimal compression
Best: High compression level
Uncompressed: No compression whatsoever
Level(u8): Detailed compression level between 1 and 9
