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
