GIFCLRMP(1)

💖 gifclrmp — extract colormaps from GIF images 💖

okay bestie, gather round, because this little cutie lives in the GIFLIB Documentation and it's here to mess with your GIF colormaps. no cap.

✨ SYNOPSIS ✨

gifclrmp [-v] [-s] [-l mapfile] [-t trans] [-g gamma] [-i image] [-h]
         [gif-file]

🌸 DESCRIPTION 🌸

so like, gifclrmp is a whole program whose entire personality is modifying GIF image colormaps. 💅

any local colormap inside a GIF file can be modified one at a time, or you can go for the global screen one instead. pick your fighter. 🫶

💅 OPTIONS 💅

• -v — verbose mode, aka the "tell me everything" setting (show progress). it enables printout of running scan lines. she's chatty and we love that for her. 💬
• -s — select the global screen color map. the big one. the main character. 👑
• -l mapfile — load color map from this file instead of the selected color map. swap in a whole new palette, iconic. 🎨
• -t trans — change color index values. the change is made to both the selected color table and the raster bits of the selected image. a translation file is a list of pairs of before and after index values. and listen — at present, the before index values must be in ascending order starting from 0. that's the rules, bestie, don't fight them. 😭
• -g gamma — apply gamma correction to the selected color map. glow-up but mathematically. ✨
• -i image — select the color map of the numbered image. yes, numbered, so pick your fave. 🖼️
• -h — print one command line help, similar to Usage above. the little "help me" button. 🙈

and if no GIF file is given, gifclip will try to read a GIF file from stdin. (yes, it says gifclip — that's literally what the page says, i'm not making this up 💀)

🎀 NOTES 🎀

• the default operation is to dump out the selected color map in text format. so if you just run it with no fancy flags, that's the vibe check you're getting. 📝
• the file to load/dump is simply one color map entry per line. each such entry line has four integers: "ColorIndex Red Green Blue", where color index is in ascending order starting from 1. yes, starting from 1, not 0, we don't make the rules. ⭐
