DPI - yintoni na? Indlela yokulungisa i DPI

Ngokuphathelele akhronimi ezahlukeneyo kunye okunzima zobugcisa. DPI - oko kukuthi? Le kunciphiso umyili ezaziwayo-kakuhle, inzululwazi ikhompyutha, abo kanye asebenza kunye nomfanekiso. Eli binzana weva kunye nabadlala kunye kwamakhwapha phawu opholileyo. Ngoku zama ukujongana nale segama.

ongakhetha

Ukuba nicela intanethi malunga DPI, oko kukuthi, yaye apho kufanelekileyo, uza kufumana iimpendulo eziliqela. Ngapha koko, kukho khowudi yasiwa kumbhalo ezintathu izifinyezo:

• Deep pak Ukuhlolwa - ababoneleli isixhobo, eqokelela manani, khangela iipakethi network lokucoca kunye neziqulatho zazo.
• Ngesaphulelo Index inzuzo ebonakalayo - yinto komnotho elinoxanduva inzala kutyalo-mali.
• Amachaphaza nge-intshi - kunye translation IsiNgesi njenge "amachaphaza nge-intshi".

Loo ukhetho lokugqibela siza kuqwalasela.

iphepha-mvume

Ukuba sithethe ngokuthe ngqo DPI, kuye kucace ukuba iyunithi yokulinganisa. Kodwa yintoni? Kubonakala ukuba bafunde irizolyushini yokuthatha umfanekiso yaye wasebenzisa eli segama.

Sigqibo ngokwayo - ngesalathisi leyo ibonisa inani amachaphaza (pixels) per unit ndawo. Amaninzi, le isalathiso isebenza uhlobo kwemifanekiso digital, kodwa isetyenziswa granulation iifilim lokufota, amaphepha njalo njalo. N.

Ngoko ke, ukuba ufuna ukugcina data kwi umfanekiso wefayile ngokobukhulu yakho ezifunwayo zazise konke oko ushicilelo, ngoko kunokwenzeka, DPI uya kuza kusinceda. Eli xabiso ibonisa inani amachaphaza nge-intshi. Ukuba unayo dpi 300, ngokulandelelana, oko ilingana amachaphaza 300 nge-intshi.

umzekelo

Omnye umzekelo, ukuze baqonde indlela eli xabiso. Masithi umfanekiso wakho lesisombululo 350 dpi. Kufuneka ulithumele ubungakanani bephepha-10 nge-10 cm. Iguqulelwe intshi wena ufumane 3.9 x 3.9 intshi. Ukuze uqonde into efunekayo ubungakanani bemifanekiso yokuqala kufuneka 3.9 liphindaphindwe 300. Ngoko sifumana 1170 x 1170 pixels. Ngesi index umgangatho umfanekiso yamkelekile.

isicelo

Ngoku ngakumbi apho nendlela yokusebenzisa DPI. Oko kukuthi, sele kusetyenzwa. Ixabiso isetyenziselwa ukucacisa isisombululo. Uphelileyo, sifuna Ukuveliswa yomfanekiso data kwi ngenkxaso flat.

Eli xabiso eninokuzifumana ngokweemfuno umshicileli. 600 kubonakala dpi-450. Ngoko kucacile ukuba icebo sinikezwe yesisombululo apho 600 amachaphaza tye kunye amachaphaza nkqo 450. Kule ndawo ye square athathe 1 1 inch.

Ukuba sithethe malunga umshicileli, ntonje eli nani kuthelekiswa PPI. Ezi amaxabiso amabini zimele into efanayo. Sebenzisa ukuba ufuna ukuxuba imibala ezakushicilelwa. Ngoko 1 iya kulingana 1 ppi dpi. Ukuba ifowuni akuyomfuneko ukuba umxube ngainki, le fomyula ukuthanda look ezahlukeneyo. Isebenzisa i index N, ebonisa inani lemibala uyisebenzise yoshicilelo. Emva koko ppi dpi lilingana liphindaphindwe ngenani ophezu index N.

Le kubalwa inzuzo iphambili inkjet abashicileli. Ngokungafaniyo fotomashin, izixhobo ezineentambo ezinkulu Isalathisi ixabiso elingana nexabiso kwi DPI PPI nayo. Njengoko wafaka amanqaku angaphezulu ukuba udlule pixel enye.

neminye imiqondiso

umfanekiso DPI - alikho ixabiso kuphela yogunyaziso. Njengoko sifundile, Kukho ubundlelwane kunye nezinye ezifana indicators. Ngoko ke, ngo abashicileli yeraster point imelwe nobuninzi ngamachaphaza ezincinane. Zibizwa ngokuba flash. Inani ukubaneka ezinjalo nge-intshi kwaye ingabonisa DPI. Inani lamanqaku yeraster ezifihlakeleyo kule ukuqhambuka intshi eyodwa ingabonisa PPI. Ngako oko, ukuba lulwahlulo indices ezimbini mkhulu umgangatho umfanekiso.

Kukho esinye ngaphezulu Isalathisi - i LPI. Ixabiso ibonisa inani imigca-intshi. Esi sigqibo ichaza ukusebenza laser printer. Inch kulo mzekelo imelwe hayi indawo, njengokuba ngaphambili, kodwa umgca. Oko kukuthi, ukuba ngqo ngakumbi ekuqulunqeni, lo LPI - linani imigca-intshi yomgama.

Enye ixabiso bubonakaliswe ungayiqondiyo SPI. Ibonisa inani amabala nezakhiwo. Isalathisi kakhulu inzima kwaye ngoko isoloko isetyenziswa kushicilelo. Kodwa ngokubanzi isetyenziselwa ukuthambeka yoshicilelo. Ke ukuba PPI ibhekisela ekupheleni yoko, i-SPI - kuyinxalenye yenkqubo. Okubangel 'umdla kukuba, ngokubanzi zombini manani anentetho enye phantsi kweemeko ngokulinganayo.

zomdlalo mouse

Kodwa kwenzeka ukuba yonke ingcaciso malunga DPI. Oko kukuthi, siyaqonda ngokwalo jikelele. Yintoni kuyasebenza Wayeqonda. Kodwa iphuthe into. Inyaniso ukuba ixabiso idla ifumaneka kumqulu kunye iimpuku yokudlala. Nikezela kwafika ngaphambili inkcazelo evela eneqikili iparameters nzima. Kodwa ungazama.

Isibakala sokuba dpi, eli limi ngokunjalo, kodwa ukuqonda eyahlukileyo kancinane. Ukuze ube ngqo, mouse, eli nani kungcono States njengoko amachaphaza of isalathisi montion-intshi. Oko kukuthi, inani amachaphaza nge-intshi intshukumo yesalathisi. Ecaleni ukuba ixabiso iyasetyenziswa kweCPI. Yena kalukhuni, athetha into enye, yaye oko bekuya kuba sengqiqweni ukulisebenzisa mfutshane. Kodwa jikelele, inye owesibini ixabiso linani maza amanyathelo esentlango eneqikili 1 inch.

Kwaye kuyimfuneko ukuqonda ukuba sithetha intshukumo isalathisi se mouse endaweni. Movement kulo mzekelo kukuthi ngentetho evakalayo njengenyathelo, linyathelo like umqondiso. Ukuba isalathiso dpi ephakamileyo, iyunithi ihamba kakuhle.

Marketing?

Le mbono ukuba eli nani, abakhala evela amaphetshana zentengiso kunye neepakethe na ngaphezu kokuba amacebo okuthengisa. Kwinto yokuba bambalwa abantu bazi, kodwa le isantya kanye asingekhe silibale ngayo nezibuko rate yokuvotela. Yinto eyaziwayo ukuba okwangoku izinga eliphezulu 1000 Hz. Wena bacinga ukuba xa imouse kuqhutywa kwithuba elinye intshi 2 yesibini, ngoko eli nani liya kabini. Enyanisweni, kuvela ahanjiswayo anqumla umbundu 1000 Hz baya kusebenza. Ngoko ke ukugqithisela eli xabiso kwi ikhiphedi?

DPI - oku sisalathisi eguqula isantya isalathisi kwidispleyi. Kwaye ke kakhulu kakuhle ngayo kwimeko izikrini ophezulu isisombululo. Ngoko kusengqiqweni ukuba xa umboniso umkhulu, le mouse kufuneka bahambe umgama ngokomlinganiselo idiagonal kwimonitha. Ngoko ke, ixabiso kubalulekile nje ukuba abadlali kunye nabo basebenza kunye nemizobo. Kubo, oyintsobi yalowo 1600 dpi eyamkelekileyo.

Kuba abanye abasebenzisi, ngubani na screen encinci 1600x1200 wanele, kunye 800 dpi. Eli xabiso yi-avareji ukuza kuthi ga ngoku. Ukuba esweni yi 1200x800, ngoko kuya kuba ngokwaneleyo kunye mouse enesisombululo ka 400-500 dpi.

iziphumo

Kucaca ukuba DPI - elinexabiso uqhelene kwezininzi nabayili, abo umsebenzi kunye yemizobo bokuprinta. Esi sigunyaziso, okuvumela ukufumanisa inani amachaphaza nge-intshi xa ukuxhonywa a flat ngenkxaso. Ukuba sithetha mouse, i-DPI kulo mzekelo ubonisa intshukumo dpi mouse.

Ukuba unayo ungumdlali mouse, umbuzo indlela ukunyenyisa DPI, akufunekanga, ngenxa yokuba kubhaliwe ngokwesiqhelo kwi ukunyenyisa kwisigqibo ngokumalunga ityala a njengeqhosha elithile. Kwezinye iimeko, ungaqwalasela nokuba nge software. Ukuba unayo eqhelekileyo mouse, kodwa Ufuna ukulungisa yayo isantya, loo nto iya kuba yanele ukuba uye kuseto phezu PC amisiweyo umtyibilikisi ofunekayo kwinqanaba.
