PNMARITH(1)

💖 PNMARITH 💖

okay bestie, welcome to the Pnmarith User Manual — section 1 of the General Commands Manual, obviously, we're fancy like that ✨

🌸 NAME 🌸

pnmarith — bestie... it's been replaced by pamarith 😭

---

🦋 DESCRIPTION 🦋

so this little program is part of Netpbm(1), okay? like, it's in the family 💜

but here's the tea: starting with Netpbm 10.3, pnmarith is obsolete fr fr. Use pamarith(1) instead. periodt. 💅

now, pamarith is backward compatible with pnmarith — iconic of it — except where your input images have different depths. here's what was going on:

• pnmarith would convert the one with the lesser depth to have the higher depth before doing the arithmetic. so helpful of it 🥺
• with pamarith, you have to do that step separately, using pgmtoppm. yeah... do it yourself, main character energy ✨
