Hapana mhinduro chaiyo kumubvunzo uyu
Iyo mapikisi nemahora inenge (PPI) yekuratidzira ndiyo inonzi inonzi pixel mashizha uye chaizvoizvo chaiyo mapikisi emazhinji aunogona kuverenga kana iwe uchiverenga mapikisiki, akajeka kana kuti akajeka, aripo mune imwe masendiki paunoratidza.
Pane zvikonzero zvinoverengeka nei uchiziva kuti mapiyona akawanda ari mune inch yekuratidzira kwako, asi kazhinji izvi zvinonyanya kubatsira apo uri kuedza kufungidzira kuti chifananidzo chiri pachiwindo chako chinogona kutarisa pane rimwe skrini.
Chimwe chirevo chinowanzoitwa ndeyekuti unoda kuziva chiratidziro kana PPI yepirinki kuti unzwisise kuti mifananidzo yakareba kana duku ingaoneka sei kana yakadhindwa, asi iwe hausi kunyanya munyaya iyi. Zvimwe pane zviri pasi apa.
Hakuchina Mhinduro Kuna Pixels per Inch
Kana mapikisi ese ese aive akaenzana, mapikiseti mu inch ingadai yakave nhamba inozivikanwa seyo yakawanda mamita masentimita mune inch (2.54) kana kuti yakareba masendimita mune tsoka (12).
Zvisinei, mapizikisi akasiyana-siyana pazviratidzo zvakasiyana , saka mhinduro ndeye 58.74 pixels pamasendimita pane "terevhizheni 4K", semuenzaniso, uye 440.58 pixels pamasendiki pa "Full HD smartphone screen.
Mune mamwe mazwi, ingani mapikisikisi pamasendiki anobva paukuru uye kugadzirisa kwechirongwa chaunenge uchitaura nezvazvo, saka tichafanirwa kuita mamwe masvomhu kuti tipe nhamba yaunotevera yako.
Nzira yekuverenga ma Pixels mune Inch
Tisati tapinda maitiro akafanana neakawanda mathemoni (hazvisi, musanetseka), takaita basa rakaoma kwamuri nokuda kwezviverengero zvakawanda muPixels Per Inch Table iri pasi peji.
Kana ukawana chiratidzo chako chePPI, enda kuNzira yekushandisa nayo Pixels yako Nhamba yeInch , asi kana zvisingaiti, tichazviona iye zvino nematanho mashoma emasvomhu.
Zvamunoda mune chero zvipi zvayo ndeyekuenzanisa kwechidimbu pakukura kwemasentimita pamwe nekugadzirisa kwekona . Zvose izvi nhamba dzinogona kuwanika pane peji yezvigadzirwa zvezvese zvekuratidzira kwako kana chigadzirwa.

Heino huwandu hwakazara hwewe mathematics savvy folks, asi ramba uchienda mberi uchienda kune iyo mazano ekufamba-nhanho:
ppi = (√ ( w ² + h²)) / d... apo ppi ndiyo mapikisi nemahora inenge uri kuedza kuwana, w ihupamhi sarudzo mumapikisikisi, h isarudzo yakakwirira mumapikiseli, uye d ishi diagonal yekrini mu inches.
Kana iwe ukarara panguva yekuraira kwekushanda chitsauko mumatunhu echikwata, hezvino iwe unoita sei izvi nemuenzaniso we 60 "4K (3840x2160) skrini:
- Ita kuti mapekisi ekufara akare : 3840 ² 14745 600
- Itai mapekisi emarefu : 2160 ² = 4 665 600
- Wedzera nhamba idzi pamwe chete: 14 745 600 + 4 665 600 = 19 411 200
- Tora rutivi rwakakosha rwechiwero ichocho: √ (19411,200) = 4405.814
- Gurai nhamba iyoyo neyeri diagonal screen measure: 4 405 814/60 = 73.43
Mumatanho mashomanana mashanu, takaona mapikiseti mumasendimita pane 60 "4k televivhoni kuva 73.43 PPI.Zvose zvaunoda kuita ikozvino zvinodzokorora matanho mashanu aya nekuratidzira kwako , uchishandisa svondo rako nekugadzirisa nekukura.
Saka zvino iwe unoziva yako kuratidza PPI ... asi chii chakanaka? Dai iwe wakanga uchingoda kuziva, wapedza! Zvisinei, sezvataitaura mune zvataurwa pamusoro apa, nguva yakawanda chigadzirwa kana kuratidza PPI ndiyo yekutanga matanho maviri ekuwana kune chimwe chinhu chinoshanda.

Iye zvino zvaunoziva muchengeti wako kana chipikicha PPI, inguva yekuishandisa zvakanaka.
Tsvaga Kuti Big Big Image Rinotarisa Sei Rimwe Chiridzwa
Iwe unogona kuumba kana kuchinja mufananidzo pa 17 yako "laptop neHCD skrini (129.584 PPI) asi uzive kuti uchave uchiratidza pane 84" 4K UHD kuratidza (52.45 PPI) muhofisi vhiki inotevera.
Iwe unogona sei kuva nechokwadi kuti chifananidzo chirikusikwa chakakura zvakakwana kana ine tsanangudzo yakarurama?
Kuti upindure mubvunzo uyu, iwe unofanira kutanga watanga kuziva PPI yedhidhiyo kana kuratidza iwe unoda kuziva . Takadzidza kuti tingazviita sei muchikamu chekupedzisira, kana iwe wakawana imwe kana nhamba mbiri zviri patafura iri pasi apa.
Iwe uchazofanirawo kuziva nzvimbo yakananga uye yakasvikisa pikisi yemufananidzo wako . Iwe uri kusika kana kugadzirisa kuti saka zvinofanirwa kuva nyore nyore kuti uwane pane yako giradha program.
Sezvakamboita, heino mazamu akazara kana iwe wakanyatsoda, asi mirayiridzo iri pasi apa:
hsize = w / ppi vsize = h / ppi... iyo hsize uye vsize ndiwo mazamu akareba uye akaenzana mumasentimita, zvichienderana, pane imwe kuratidzwa, w ndiwo hupamhi hwechifananidzo mumapiksesi, h ndiyo kukwirira kwechifananidzo mumapikiseli, uye ppi i PPI ye rimwe rinoratidza.
Heuno maitiro ako kuita izvi kana mufananidzo wako 950x375 pixels muhukuru uye chiratidziro chauri kuronga ndeye 84 "4K (3840x2160) skrini (52.45 PPI):
- Gura upamhi nePPI: 950 / 52.45 = 18.11 "
- Gurai kukwirira ne PPI: 375 / 52.45 = 7.15 "
Pano isu takaratidza izvozvo, zvisinei kuti "guru" kana kuti "duku" chifananidzo chinogona kuonekwa kuva pachikona chako , nepikisi yezvikamu zve 950x375, chifananidzo ichocho chichaonekwa kuva 18.11 "na7.15" pane 84 "4K TV it ' Icharatidzwa.
Iye zvino unogona kushandisa ruzivo irworwo sezvaunoona zvakakodzera ... zvichida ndizvo zvawakanga uri shure, kana zvichida hazvina kukwana zvakakwana zvichifunga kuti 84 "chinyorwa chinenge 73" kumativi uye 41 "kureba!
Sarudzai Kukura Mufananidzo Wechipi Uchapindira paZvigadziriswa Zvakakwana
Nenzira yakanaka, haufaniri kuverenga chimbo chako kana kuratidza PPI kuti uone kuti chikuru sei chinyorwa iwe chachinyora chichava pamapepa.
Zvose zvaunoda kuziva ndezvipi izvo zviri mumufananidzo wacho pachawo - pikisi yepikisi yepamusoro , vertical pixel dimension , uye PPI yemufananidzo .
Zvose zvitatu zvemashoko zvinowanikwa muzvifananidzo zvemufananidzo waunogona kuwana muurongwa hwako hwekugadzirisa.
Heano kuenzanisa:
hsize = w / ppi vsize = h / ppi... iyo hsize uye vsize ndiwo mazamu akaenzana uye akaenzana mumasentimita, zvichienderana, sezvaanenge achidhindwa, w ihwo upamhi hwechifananidzo mumapikiseli, h ndiko kukwirira kwechifananidzo mu pixels, uye ppi ndiyo PPI yemufananidzo wacho pachako.
Heuno maitiro aunozviita kana chifananidzo chako chiri 375x148 pixels muhukuru uye ine PPI ye 72:
- Gura upamhi nePPI: 375/72 = 5.21 "
- Gurai kukwirira kwePII: 148/72 = 2.06 "
Tichifunga kuti hauna kuwedzera mufananidzo panguva yekudhinda, chifananidzo chichadhindwa zvakasikwa pahukuru hwe 5.21 "ne 2.06". Ita mathemati nemufananidzo waunoita uye wozvinyora kunze - inoshanda nguva dzose!
Cherechedza: DPI inogadzirisa kuti printer yako inogadziriswa, ingava 300, 600, 1200, nezvimwewo, haibatsiri kukura kwechifananidzo chacho! Nhamba iyi yakafanana zvikuru nePPI uye inomiririra "unhu" iyo iyo mifananidzo yakatumirwa ku printer inodhindwa neye asi haifaniri kuiswa sechikamu chekukura kwemafananidzo ako.
