exrblur(1)

💖 NAME 💖

okay bestie, welcome to exrblur(1) from the General Commands Manual — the tiny icon whose whole personality is: exrblur does a gaussian blur on an OpenEXR image. no cap. 💅

✨ SYNOPSIS ✨

exrblur input.exr output.exr kernelsize

like, that's the whole summoning ritual: input.exr, then output.exr, then kernelsize. 🫶

🌸 DESCRIPTION 🌸

So exrblur performs a gaussian blur on the input image. iconic. This is useful for generating a whitepoint image for chromatic adaptation of locally adapting tone mapping algorithms. yes, she said all of that, and she ate. ✨

The kernel size for the blur is given as a fraction of the image width. So, a kernelsize of 0.25 will perform a blur with a kernel width 1/4 of the image width. math girlie moment, fr fr. 🎀

lowkey important: kernelsize is a fraction of the image width. 0.25 = 1/4 of the image width. periodt. 💅
