Macros§

IndexSet: A hash set where the iteration order of the values is independent of their hash values.
Options: Options controlling the output of the optimize function
RawImage: A raw image definition which can be used to create an optimized png
ZopfliOptions: Options for the Zopfli compression algorithm.

BitDepth: The number of bits to be used per channel per pixel
ColorType: The color type used to represent this image

OutFile: Write destination for optimize. You can use optimize_from_memory to avoid external I/O.
PngError
RowFilter: PNG delta filters
StripChunks: Options to use when stripping chunks (metadata)

optimize: Perform optimization on the input file using the options provided
optimize_from_memory: Perform optimization on the input file using the options provided, where the file is already loaded in-memory
