Rust is installed now. Great!

To get started you need Cargo's bin directory (%USERPROFILE%.cargo\bin) in your
PATH
environment variable. Future applications will automatically have the
correct environment, but you may need to restart your current shell.

pngquant, 2.12.0 (January 2018), by Kornel Lesinski, Greg Roelofs.
   Color profiles are supported via Little CMS. Using libpng 1.6.37.

usage:  pngquant [options] [ncolors] -- pngfile [pngfile ...]
        pngquant [options] [ncolors] - >stdout <stdin

options:
  --force           overwrite existing output files (synonym: -f)
  --skip-if-larger  only save converted files if they're smaller than original
  --output file     destination file path to use instead of --ext (synonym: -o)
  --ext new.png     set custom suffix/extension for output filenames
  --quality min-max don't save below min, use fewer colors below max (0-100)
  --speed N         speed/quality trade-off. 1=slow, 3=default, 11=fast & rough
  --nofs            disable Floyd-Steinberg dithering
  --posterize N     output lower-precision color (e.g. for ARGB4444 output)
  --strip           remove optional metadata (default on Mac)
  --verbose         print status messages (synonym: -v)

Quantizes one or more 32-bit RGBA PNGs to 8-bit (or smaller) RGBA-palette.
The output filename is the same as the input name except that
it ends in "-fs8.png", "-or8.png" or your custom extension (unless the
input is stdin, in which case the quantized image will go to stdout).
If you pass the special output path "-" and a single input file, that file
will be processed and the quantized image will go to stdout.
The default behavior if the output file exists is to skip the conversion;
use --force to overwrite. See man page for full list of options.

PNGOUT [In:{PNG,JPG,GIF,TGA,PCX,BMP}] (Out:PNG) (options...)        Feb 13 2015
by Ken Silverman (http://advsys.net/ken)
PNGOUT optimizes PNG size losslessly using my own deflate algorithm (not Zlib)
With the right options, it can often beat other programs by 5-10%.

PNGOUT [In:{PNG,JPG,GIF,TGA,PCX,BMP}] (Out:PNG) (options...)        Feb 13 2015
by Ken Silverman (http://advsys.net/ken)
PNGOUT optimizes PNG size losslessly using my own deflate algorithm (not Zlib)
With the right options, it can often beat other programs by 5-10%. Options:
   /c# PNG output color: 0=Gray, 2=RGB, 3=Pal, 4=Gray+Alpha, 6=RGB+Alpha
   /f# PNG output filter: 0=none, 1=x, 2=y, 3=x&y, 4=Paeth, 5=mixed, 6=reuse
   /d# Override default bitdepth: 0(min),1,2,4,8 (valid only in /c0,/c3 modes)
   /s# Select strategy. 0:Xtreme(default), 1:Intense, 2:Longest Match,
       3:Huffman Only, 4:Uncompressed
   /b# Block split threshold (lower=more blocks, 0=1 block/file, default=256)
       Use trial&error! Suggested values to try are: 0,128,192,256,512,1024,..
   /n# Exact number of Huffman blocks (overrides /b#)
   /r  Randomized initial tables (good for many trials with same options)
   /i  Use image on windows clipboard as input (specify only output filename)
   /k? 0=Remove optional chunks (default), 1=Keep all
       p=Keep palette indices, s=Keep settings for /c,f,d,b, t=Keep file time
   /k(Chunk,Chunk,..) Preserve only named chunk(s). Example: /kgAMA,bKGD,tEXt
   /v,q,l Verbose,Quiet,List mode (use '-' as filename to specify stdin/stdout)
   /y  Assume Yes at the 'overwrite file?' prompt
   /force  Write file even if bigger.
   /mincodes#  Workaround for buggy decoders. 1:Zlib 1.2.1 bug, 2:buggy mobiles
The 1st filename is the input (except when using /i). If you omit the output
filename, PNGOUT will use the same filename with a .PNG extension. Examples:
   >pngout inlarge.bmp outsmall.png           <- writes outsmall.png
   >pngout duke3d.png /c2 /f3 /b128 /kbKGD /v <- writes duke3d.png if smaller
   >pngout /i clipboard.png                   <- writes clipboard.png
   >for %i in (*.gif) do pngout "%i" /kp      <- convert all GIFs in dir to PNG

Notes:
    The combination for -o1 is chosen heuristically.
    Exhaustive combinations such as "-o7 -zm1-9" are not generally recommended.

    optipng file.png                                            (default speed)
    optipng -o5 file.png                                        (slow)
    optipng -o7 file.png                                        (very slow)
