'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.
-b, --batch Batch mode: modify inputs, write back to
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 'input.name'.
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:
Frame change options:
--delete FRAMES Delete FRAMES from input.
--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 the image.
--crop-transparency Crop transparent borders off the image.
--flip-horizontal, --flip-vertical
Flip the image.
-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.
-n, --name TEXT Set next frame's name.
--no-comments, --no-names, --no-extensions
Remove comments (names, extensions) from input.
Animation options: Also --no-OPTION and --same-OPTION.
-d, --delay TIME Set frame delay to TIME (in 1/100sec).
-D, --disposal METHOD Set frame disposal to METHOD.
-l, --loopcount[=N] Set loop extension to N (default forever).
-O, --optimize[=LEVEL] Optimize output GIFs.
-U, --unoptimize Unoptimize input GIFs.
-j, --threads[=THREADS] Use multiple threads to improve speed.
Whole-GIF options: Also --no-OPTION.
--careful Write larger GIFs that avoid bugs in other
programs.
--change-color COL1 COL2 Change COL1 to COL2 throughout.
-k, --colors N Reduce the number of colors to N.
--color-method METHOD Set method for choosing reduced colors.
-f, --dither Dither image after changing colormap.
--gamma G Set gamma for color reduction [2.2].
--lossy[=LOSSINESS] Alter image colors to shrink output file size
at the cost of artifacts and noise.
--resize WxH Resize the output GIF to WxH.
--resize-width W Resize to width W and proportional height.
--resize-height H Resize to height H and proportional width.
--resize-fit WxH Resize if necessary to fit within WxH.
--scale XFACTOR[xYFACTOR] Scale the output GIF by XFACTORxYFACTOR.
--resize-method METHOD Set resizing method.
--resize-colors N Resize can add new colors up to N.
--transform-colormap CMD Transform each output colormap by shell CMD.
