PNGCOMP(1)
β¨ PNGCOMP(1) β like, the manual page, bestie β¨
okay so this is pngcomp, section 1 of the General Commands Manual, and I'm gonna walk you through it like we're texting at 2am π
πΈ NAME πΈ
pngcomp β the PNG (Portable Network Graphics) comparison tool. that's it, that's the whole vibe π¦
π SYNOPSIS π
pngcomp [-vVh] image1.png image2.png
like. two images. one command. comparison arc unlocked π₯
π DESCRIPTION π
so what does pngcomp actually do? it gives you some basic statistics about the difference between two images π«Ά literally the whole point. it was created as a measure of various color quantization methods β so if you're out here comparing quantization techniques, this is your girl, no cap π
β OPTIONS β
-vβ Verbose. and by verbose I meanβ¦ it does nothing as yet π iconic behavior honestly, it's giving placeholder energy.-Vβ Version. prints version information, periodt.-hβ Help. prints this message. hello bestie π
π§ NOTES π§
the stats this program creates are purely based on the Euclidean distance in RGBA space between the pixels of the images π like that's the entire measure, that's the math.
later versions will include different measures such as CIE color space measurements and filters for perception models β so future her is gonna be even more powerful, we love a glow up β¨
lowkey important: the error calculation used reflects the perceived quality of images only roughly π don't treat it like gospel, okay?
and honestly?? to determine what image is better, nothing can surpass having a look for yourself! your eyes are the main character here ποΈποΈπ
