Options controlling the output of the optimize function

Fields

backup

Whether the input file should be backed up before writing the output

out_file

Path to write the output file to

out_dir

Used only in CLI interface

stdout

Write to stdout instead of a file

fix_errors

Attempt to fix errors when decoding the input file

pretend

Don't actually write any output, just calculate the best results

recursive

Used only in CLI interface

clobber

Overwrite existing output files

create

Create new output files if they don't exist

force

Write to output even if there was no improvement in compression

preserve_attrs

Ensure the output file has the same permissions as the input file

verbosity

How verbose the console logging should be (None for quiet, Some(0) for normal, Some(1) for verbose)

filter

Which filters to try on the file (0-5)

interlace

Whether to change the interlacing type of the file None will not change the current interlacing type Some(x) will change the file to interlacing mode x

compression

Which zlib compression levels to try on the file (1-9)

memory

Which zlib memory levels to try on the file (1-9)

strategies

Which zlib compression strategies to try on the file (0-3)

window

Window size to use when compressing the file, as 2^window bytes Doesn't affect compression but may affect speed and memory usage 15 is recommended default, 8-15 are valid values

bit_depth_reduction

Whether to attempt bit depth reduction

color_type_reduction

Whether to attempt color type reduction

palette_reduction

Whether to attempt palette reduction

idat_recoding

Whether to perform IDAT recoding If any type of reduction is performed, IDAT recoding will be performed regardless of this setting

strip

Which headers to strip from the PNG file, if any

use_heuristics

Whether to use heuristics to pick the best filter and compression Intended for use with -o 1 from the CLI interface
