'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: #num, #num1-num2, #num1-, #name 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]. --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. --use-colormap CMAP Set output GIF's colormap to CMAP, which can be 'web', 'gray', 'bw', or a GIF file.
