  • 其它gifsicle参数
'Gifsicle' manipulates GIF images. Its most common uses include combining
single images into animations, adding transparency, optimizing animations for
space, and printing information about GIFs.

Usage: gifsicle [OPTION | FILE | FRAME]...

Mode options: at most one, before any filenames.
  -m, --merge                   Merge mode: combine inputs, write stdout.

                                same filenames.
  -e, --explode                 Explode mode: write N files for each input,
                                one per frame, to 'input.frame-number'.
  -E, --explode-by-name         Explode mode, but write ''.

General options: Also --no-OPTION for info and verbose.
  -I, --info                    Print info about input GIFs. Two -I's means
                                normal output is not suppressed.
      --color-info, --cinfo     --info plus colormap details.
      --extension-info, --xinfo --info plus extension details.
      --size-info, --sinfo      --info plus compression information.
  -V, --verbose                 Prints progress information.
  -h, --help                    Print this message and exit.
      --version                 Print version number and exit.
  -o, --output FILE             Write output to FILE.
  -w, --no-warnings             Don't report warnings.
      --no-ignore-errors        Quit on very erroneous input GIFs.
      --conserve-memory         Conserve memory at the expense of speed.
      --multifile               Support concatenated GIF files.

Frame selections:               #num, #num1-num2, #num1-, #name

Frame change options:

  --insert-before FRAME GIFS    Insert GIFS before FRAMES in input.
  --append GIFS                 Append GIFS to input.
  --replace FRAMES GIFS         Replace FRAMES with GIFS in input.
  --done                        Done with frame changes.

Image options: Also --no-OPTION and --same-OPTION.
  -B, --background COL          Make COL the background color.
      --crop X,Y+WxH, --crop X,Y-X2,Y2

      --crop-transparency       Crop transparent borders off the image.
      --flip-horizontal, --flip-vertical

  -i, --interlace               Turn on interlacing.
  -S, --logical-screen WxH      Set logical screen to WxH.
  -p, --position X,Y            Set frame position to (X,Y).
      --rotate-90, --rotate-180, --rotate-270, --no-rotate
                                Rotate the image.
  -t, --transparent COL         Make COL transparent.

Extension options:
      --app-extension N D       Add an app extension named N with data D.
  -c, --comment TEXT            Add a comment before the next frame.
      --extension N D           Add an extension number N with data D.
