Akukho mpendulo efanelekileyo kulo mbuzo
Iipekseli nge intshi (PPI) yesibonakaliso yinto ekubhekiswa kuyo njenge- pixel ukuxininisa kwaye ngokwenene ngokoqobo ukuba ungaphila iipikseli ukuba ubale iipikseli, ezizenzekelayo okanye ezizenzekelayo, ezikhoyo kwi-intshi enye kwi-bonisi yakho.
Kukho izizathu ezininzi zokuba kutheni uninzi lweepekseli zikhona kwi intshi yakho yokubonisa, kodwa ngokuqhelekileyo oku kunceda xa uzama ukucinga indlela umfanekiso onkrini yakho inokujonga ngayo kwesikrini ehlukile.
Olunye uqikelelo oluqhelekileyo kukuba kufuneka ufunde umboniso okanye iPrint yephrinta ukuze uqonde ukuba umkhulu okanye umncinane umfanekiso ungabonakala xa ushicilelwe, kodwa ngokwenene awukho kulo mzekelo. Oku ngakumbi ngezantsi.
Ayikho Impendulo kwiPixels nganye nge intshi
Ukuba zonke iipekseli zazilinganiso ezifanayo, iipikseli nge-intshi yayiza kuba nenombolo eyaziwayo njengangaphi iisentimitha kwisentimitha (2.54) okanye zingangama intshi ezinyawo (12).
Nangona kunjalo, iipekseli zibukhulu obuhlukeneyo kwimiboniso eyahlukeneyo , ngoko impendulo i-pixels engama-58.74 nge-intshi kwi-75 "ithelevishini ye-4K, umzekelo, kunye ne-440.58 ipilisi nge-inch kwi-5" I-HD epheleleyo ye-smartphone.
Ngamanye amazwi, zingaphi iipikseli nge intshi zixhomekeke kubukhulu kunye nesisombululo sesicatshulwa othetha ngaso, ngoko kuya kufuneka senze ezinye izibalo ukuze sibone inombolo oyilandelayo eyakho.
Indlela yokubala iiPixel kwi-intshi
Ngaphambi kokuba singene kwizinto ezinjengeematriki eziphambili (akunjalo, musa ukukhathazeka), senze umsebenzi onzima kuwe ngenani leemiboniso kwii- Pixels nge-Inch Table ezantsi kwephepha.
Ukuba ufumana isibonakaliso sakho sePPI, qhubela phambili kwiNkqubo yokuSebenzisa iiPixel zakho ngeNombolo yeInchintshi , kodwa ukuba akunjalo, siya kuwuqonda apha ngeendlela ezimbalwa zeemathematika ezilula.
Oko uza kuyidinga nakweyiphi na imeko ubukhulu bokuboniswa kwee-inches kunye nesisombululo seskrini . Zombili zala manani zingatholakala kwiphepha leenkcukacha zobugcisa bokubonisa okanye isixhobo sakho.
Jonga indlela yokufumana iNkcukacha yeNkxaso yeTech Manufacturer ukuba ufuna uncedo lokumba oku.
Nantsi ukulingana okupheleleyo kwimiba yolwazi lwe-math, kodwa yeqa ngokugqithiseleyo ekudlulileyo kwinqanaba elihamba ngesinyathelo:
ppi = (√ ( w ² + h²)) / d... apho ipipi iipikseli nge intshi ozama ukuyifumana, w isisombululo esibanzi kwii-pixels, h isisombululo sokuphakama kwii-pixels, kwaye d ubukhulu becala beskrini kwiintshi.
Ukuba ulala ngexesha lomsebenzi wesahluko kwiiklasi zezibalo, yile ndlela uyenza ngayo umzekelo we-60 "4K (3840x2160) isikrini:
- I-Square ipakseli ebanzi : 3840² = 14,745,600
- Iipaki zeepikseli zokuphakama : 2160² = 4,665,600
- Yongeza loo manani kunye: 14,745,600 + 4,665,600 = 19,411,200
- Thatha ingcambu yecala yale nombolo: √ (19,411,200) = 4,405.814
- Hlukanisa loo nombolo ngesilinganiselo se- screen diagonal: 4,405,814 / 60 = 73.43
Kwiminyathelo emfutshane emifutshane, siqikelele iipikseli nge-intshi kwi-60 "ithelevishini ye-4K ibe ngu-73.43 i-PPI. Konke okufuneka uyenze ngoku kuphinda amanyathelo amahlanu ngesiboniso sakho , usebenzisa isisombululo sakho kunye nesayizi.
Ngoko ngoku uyazi i-PPI yakho yokubonisa ... kodwa yintoni enhle? Ukuba ucinga nje, uyenziwe! Nangona kunjalo, njengoko sikhankanywe kwisingeniso esingentla, ixesha elininzi isixhobo okanye ukubonisa i-PPI kukuqala kwamanyathelo amabini ukufikelela kwinto engakumbi.
Indlela yokusebenzisa ii-pixels zakho ngenombolo ye-intshi
Ngoku ukuba uyazi isikrini sakho okanye i-PPI yexesha, ixesha lokulisebenzisa kakuhle.
Qinisekisa ukuba Ubunjani Umfanekiso Oya Kujonga Ngenye Idivayisi
Unokwenza okanye uhlele umfanekiso kwi-17 yakho yekhompyutheni ene-HD kwisikrini (129.584 PPI) kodwa uyazi ukuba uya kubonisa kwi-84 "4K ye-UHD ukubonisa (52.45 PPI) kwiofisi ezayo kwiveki.
Unokuqiniseka njani ukuba umfanekiso uyadala ngokwaneleyo okanye unenkcazelo echanekileyo?
Ukuze uphendule lo mbuzo, kufuneka uqale ukwazi i-PPI yesixhobo okanye ukubonisa ukuba ufuna ukwazi . Sifunde indlela yokwenza oko kwicandelo lokugqibela, okanye ufumene enye okanye zombini manani kwitheyibhile elingezantsi.
Uzakufuna kwakhona ukwazi ubukhulu bepikelli engamanzi kunye nomzobo womfanekiso wakho . Udala okanye uhlela ukuba ngoko kufuneka kube lula ngokwaneleyo ukufumana kwiprogram yakho yemifanekiso.
Njengangaphambili, yilezi zilinganiso ezipheleleyo ukuba unomdla, kodwa imiyalelo ingezantsi:
hsize = w / ppi vsize = h / ppi... apho i- hsize kunye ne- vsize ngumlinganiselo wesigxina kunye nesobukhulu kumatshini , ngokulandelanayo, kwesinye isibonakaliso, w ububanzi bomfanekiso kwiipikseli, h ubude bomfanekiso kwii-pixels, kunye ne- ppi yi-PPI omnye umboniso.
Nantsi indlela oyenza ngayo ukuba umfanekiso wakho ngu-950x375 pixels ngobukhulu kunye nomboniso ocebayo ngu-84 "4K (3840x2160) isikrini (52.45 PPI):
- Hlula ububanzi ngePPI : 950 / 52.45 = 18.11 "
- Ukwahlula ukuphakama ngePPI : 375 / 52.45 = 7.15 "
Lapha sibonise ukuba, kungakhathaliseki ukuba "inkulu" okanye "incinci" umfanekiso unokubonakala ngathi usekhompyutheni yakho , kunye nobukhulu bepikelel ye-950x375, loo mfanekiso iya kubonakala ibe ngu-18.11 "ngo-7.15" kwi-84 " iza kuboniswa.
Ngoku ungasebenzisa olo lwazi njengoko ubona lufanelekile ... mhlawumbi yile nto uyenayo emva kwayo, okanye mhlawumbi akukho mkhulu ngokwaneleyo ekucingeni ukuba i-"isikrini" singama-73 "ngaphaya nangama-41" ende!
Qinisekisa ubungakanani beSithombe Esiza kuPrinta kwiSigqibo esipheleleyo
Ngethamsanqa, akudingeki ukuba ufumane ifowuni yakho okanye ubonise iPPI ukujonga ukuba umkhulu kangakanani umfanekiso oprintelayo uya kuba sephepha.
Yonke into ofuna ukuyifumana yolwazi oluqulethwe kumfanekiso ngokwawo - ubukhulu bepikelel, ubukhulu bepikelli , kunye nePPI yomfanekiso .
Zonke iinkalo ezintathu zedatha zifumaneka kwiipropati zomfanekiso ongayifumana kwinkqubo yakho yokuhlela imifanekiso.
Nazi izibalo:
hsize = w / ppi vsize = h / ppi... apho i- hsize kunye ne- vsize zizobunzima bomfanekiso obunamanqanaba kunye namaqondo angama-intshi, ngokulandelanayo, njengoko ziya kuprintwa, w ububanzi bomfanekiso kwii-pixels, h ubude bomfanekiso kwii-pixels, kunye ne- ppi IPPI yomfanekiso ngokwawo.
Nantsi indlela oyenza ngayo ukuba umfanekiso wakho ungama-pixels angama-375x148 ngobukhulu kwaye unePPI ye-72:
- Hlula ububanzi ngePPI: 375/72 = 5.21 "
- Ukwahlula ukuphakama ngePPI: 148/72 = 2.06 "
Ukucinga ukuba awuyikukrazula umfanekiso ngexesha lokunyathelisa, umfanekiso uya kuprintwa ngokomzimba ngo-5.21 "nge-2.06". Yenza imathematika ngomfanekiso onayo uze uyiprinte ngaphandle - isebenza njalo!
Qaphela: Isisombululo se-DPI umshicileli wakho usemiselweyo , ngaba yi-300, 600, 1200, njl., Akunakuchaphazela ubungakanani bokuthi umfanekiso ushicilelwe! Le nombolo ifana kakhulu ne-PPI kwaye ibonisa "umgangatho" apho umfanekiso othunyelwe kumshicileli ushicilelwe kunye kodwa akufanele ufakwe njengenxalenye yobunzima bobukhulu bomfanekiso wakho.
Iipikseli ngeThiki yeThikidi
Njengoko uthembisile ngasentla, apha iPPI yethu "yokukopela" ifanele ikulondoloze izibalo ezininzi eziboniswe ngasentla.
