Kukhishwe ngo-1992, i-Twain iyinhlangano ejwayelekile yokukhonjiswa kwe-Windows ne-Macintosh evumela ukuthi amadivayisi we-hardware ama-imaging (afana ne-scanner namakhamera we-digital) ukuxhumana nesofthiwe yokucubungula isithombe.
Ngaphambi kwe-TWAIN, amadivaysi okuthola isithombe aso sonke afika ne-software yabo yokuthengisa. Uma ufuna ukusebenzisana nesithombe esithwetshiwe kuhlelo lokusebenza oluhlukile, kuzomele ulondoloze isithombe ku-disk kuqala, bese uvula uhlelo lokusebenza olukhethile bese uvula isithombe lapho.
Cishe sonke isofthiwe yokucubungula izithombe namuhla i-TWAIN ehambisanayo. Uma ngabe isofthiwe yakho isekela i-TWAIN, uzothola umyalo othi "thola" kumamenyu noma amabha yamathuluzi (nakuba ngezinye izikhathi umyalo ufihliwe ngaphansi kwemenyu yokungenisa).
Lo myalo unikeza ukufinyelela kunoma yiziphi amadivayisi we-hardware we-TWAIN efakwe ohlelweni. Nakuba ukubukeka kwesofthiwe namakhono wedivaysi ngayinye kungahluka, umyalo we-TWAIN Uthole uphawula isofthiwe ye-hardware interfacing, futhi ubeka isithombe esitholakale kwisofthiwe yokucubungula isithombe, ngaphandle kwesidingo sokuthi isithombe sizogcinwa kuqala kwi disk.
Ngakho-ke yini okumele ilandelwe ngempela? Ngokusho kwe-Free On-Line Dictionary ye-Computing futhi igcizelelwe yi-Web Site esemthethweni yeqembu le-TWAIN, akuyona into ecacile:
Igama elithi TWAIN livela ku-Kipling's "I-Ballad ye-East ne-West" - "... futhi akekho ababili abazohlangana ...", kubonisa ubunzima, ngesikhathi, zokuxhuma ama-scanners namakhompyutha abo. Kwakuphakanyisiwe ku-TWAIN ukwenza kube okuhlukile kakhulu. Lokhu kwaholela abantu ukuba bakholelwe ukuthi kwakuyisiqubulo, bese emncintiswaneni ukuza nokwanda. Akukho okukhethiwe, kodwa ukungena "Ubuchwepheshe Bungekho Igama Ethakazelisayo" kuyaqhubeka nokukhipha indinganiso.

Ukusetshenziswa okujwayelekile kwe-TWAIN ukuvumela ukuskena kwezithombe ngokuqondile ku- Photoshop . Lokhu kuye kwaba nzima nakakhulu ukuqala ngokukhululwa kwe-Photoshop CS5 futhi kuqhubeka kuze kube namuhla. Isizathu esiyinhloko sokuba i-Adobe yehlile ukwesekwa kwama-scanner angu-64-bit TWAIN ku-64-bit noma i-32-bit Photoshop, futhi iphakamisa nokuthi usebenzisa i-TWAIN "engozini yakho".
I-CS6 igijima kuphela ku-64-bit mode: uma umshayeli wakho weskena engakwazi ukusingatha imodi ye-64-bit, ngeke ukwazi ukusebenzisa i-TWAIN. Eqinisweni, i-TWAIN ingaba yikhokhnoloji emilenzeni yayo yokugcina. Ngokujabulisayo, i-Adobe inezinye iziphakamiso eziseduze.
