💖 pkfillnodata — bestie's guide to filling holes 💖

okay so welcome to pkfillnodata, section 1 of the manual, and no cap this little program is here to fill the holes in your raster image. holes? gone. gaps? slayed. let's get into it 🫶

---

✨ SYNOPSIS ✨

pkfillnodata -i input -m mask -o output [options] [advanced options]

like, that's the whole vibe. three required-ish things and then the fun extras 🌸

---

🦋 DESCRIPTION 🦋

So pkfillnodata fills nodata values in a raster dataset. And what counts as a nodata value, you ask? bestie, it's literally the 0 values in the mask raster dataset. periodt. that's the definition 💅

And here's the cute part: you can totally just use the input file as the mask image if the 0 values in the input raster are the ones that have to be filled. one file, two jobs, main character energy 👑

Per default, all bands are filled — every single one, no band left behind 💖. But if you're working with a multiband raster input image and you only want to fill individual band(s), use the option -b and pick your faves. iykyk ✨

🎀 OPTIONS 🎀

• -i filename, --input filename — the input raster dataset. your source material, your origin story 🌈
• -m mask, --mask mask — the mask raster dataset that indicates which pixels are getting interpolated (the zero valued ones, to be exact) 🎯
• -o filename, --output filename — the output image file. this is where the glow-up gets saved 💾✨
• -b band, --band band — which band(s) to process. Default is -1: process all bands 🎶 (yes bestie, all of them, the whole lineup)
• -v level, --verbose level — verbose. she talks more. that's it, that's the setting 🗣️

---

🔥 Advanced options 🔥

• -d distance, --distance distance — the maximum number of pixels to search in all directions to find values to interpolate from. like, how far are we willing to look for a good value? a little stroll or a full quest 🧚
• -it iterations, --iteration iterations — the number of 3x3 smoothing filter passes to run. default is 0, so by default it's giving ✨untouched✨ — but crank it up and she gets smooth 😌

⚠️ heads up bestie: keep those flags exactly as written — -it for the smoothing passes and --iteration for the long form. don't go renaming things, the program will simply not get the memo 💀
