Like but also print information about compressed image sizes. Like but also print any unrecognized GIF extensions in a hexdump(1)-likeformat. Like but also print information about input files' colormaps. Print a human-readable description of each input GIF to the standardoutput, or whatever file you specify with This option suppresses normal output, and cannot be combined with modeoptions like If you give twooroptions, however, information is printed to standard error, and normaloutput takes place as usual. The info options andcan be turned off withoq -no-Xcq. General options control the information gifsicleprints and where it writes its output. Frames are named using theoq -namecqoption. Same asbut write any named frames to files oqxxx. The output GIFs arenamed oqxxx.000cq, oqxxx.001cq, and so on, where oqxxxcq is the name of the inputfile (or whatever you specified withoq -outputcq)and the numeric extension is the frame number. Modify each GIF input in place by reading and writing to the same filename.(GIFs read from the standard input are written to the standard output.) Create an output GIF for each frame of each input file. Combine all GIF inputs into one file with multiple frames and write thatfile to the standard output. There can be at most one, and it mustprecede any GIF inputs. Mode options tell gifsiclewhat kind of output to generate. You can turn off a short optionoq -Xcqby sayingoq +Xcqinstead. Many options also have a converse,oq -no-optioncq,which turns off the option. Some options also have a short form,oq -Xcq.You can combine short options if they don't take arguments:oq -IIbcqis the same asoq -I -I -bcq.But be careful with options that do take arguments:oq -cblahcqmeansoq -c blahcq,notoq -c -b -l -a -hcq. OPTIONSĮvery option has a long form,oq -long-descriptive-namecq.You don't need to type the whole long descriptive name, just enough tomake it unambiguous. Gifsicleexits with status 0 if there were no errors and status 1 otherwise.
If no GIF input file isgiven, or you give the special filename oq-cq,it reads from the standard input. Gifsiclereads and processes GIF input files in order.

Theoption, for example, tells gifsicleto interlace its inputs: Gifsiclenormally processes input GIF files according to its command lineoptions and writes the result to the standard output.
