I-Picas isetshenziselwa ukukala ububanzi bekholomu nobubanzi
I-pica iyinithi yezinhlobo zokulinganisa ezivame ukusetshenziswa ukulinganisa imigqa yohlobo. I-pica eyodwa ilingana namaphuzu angu- 12, futhi kukhona ama-picas angu-6 kuya ku-intshi. Abakhiqizi abaningi bezithombe zedijithali basebenzisa amasentimitha njengendlela yokuzikhethela emisebenzini yabo, kodwa i-picas namaphoyinti asenabo abalandeli abaningi phakathi kwe-typographers, i-typesetters, namaphrinta ezentengiselwano.
Usayizi we-Pica
Ubukhulu bephoyinti ne-pica behluka phakathi nawo wonke ama-18 neyama-19. Noma kunjalo, izinga elisetshenziswe e-US lasungulwa ngo-1886. I-Picas yaseMelika ne-PostScript noma i-picas yekhomputha yenza isilinganiso esingu-0.166 amasentimitha. Lona isilinganiso se-pica esetshenziselwa isofthiwe yesimanje yesakhiwo sekhasi nesakhiwo sekhasi.
Yini i-Pica eyisebenzisayo?
Ngokuvamile, i-picas isetshenziselwa ukulinganisa ububanzi nokujula kwamakholomu namagqabha. Amaphuzu asetshenziselwa ukukala izakhi ezincane ekhasini elifana nohlobo nokuhola. Ngenxa yokuthi i-picas namaphoyinti asetshenziswe emaphephandabeni amaningi, kungase kudingeke ukuthi ulungiselele izikhangiso zephepha lakho lansuku zonke ku-picas namaphoyinti.
Esikhathini sesofthiwe yokuhlela ikhasi njenge-Adobe InDesign ne-Quark Express, incwadi p iveza i-picas uma isetshenziswe nge-numeral, njenge-22p noma 6p. Ngamaphuzu angu-12 ku-pica, isigamu se-pica ngamaphuzu angu-6 abhalwa njenge-0p6. Amaphuzu ayishumi nesikhombisa abhaliwe 1p5 (1 pica = amaphuzu angu-12, kanye namaphuzu angu-5 asele). Lezozinhlelo ezifanayo zezinhlelo zekhasi nazo zinikeza ngamasentimitha nezinye izilinganiso (amentimitha nama-millimeters, noma ubani?) Kubantu abangafuni ukusebenza ku-picas namaphoyinti. Ukuguqulwa kwesofthiwe phakathi kwamayunithi wokulinganisa kuyashesha.
Ku-CSS kuwebhu, isifinyezo se-pica yi-pc.
Ukuguqulwa kwe-Pica
1 intshi = 6p
1/2 intshi = 3p
1/4 intshi = 1p6 (i-pica ne-6 amaphuzu)
1/8 intshi = 0p9 (i-picas zero namaphoyinti angu-9)
Ikholomu yombhalo ongamamitha angu-2,25 ububanzi ububanzi obuyi-13p6 (ama-picas angu-13 namaphuzu angu-6)
Iphuzu eli-1 = 1/72 intshi
1 pica = 1/6 intshi
Kungani usebenzisa i-Picas?
Uma ukhululekile ngesistimu eyodwa yokulinganisa, asikho isidingo esiphuthumayo sokushintsha. Abadwebi bezithombe nabadwebi be-typographer abaye bahlala isikhashana bephethe i-pica kanye nezinhlelo zokukhomba. Kulula ngabo ukuba basebenze ku-picas njengama-intshi. Kungashintsha okufanayo kubantu abafika embonini yephephandaba.
Abanye abantu bathi i-picas kulula ukuyisebenzisa ngoba iyisistimu yesisekelo se-12 futhi ihlukaniswe kalula yi-4, 3, 2 no-6. Abanye abathandi ukusebenzisana neziqu ezivuna kusukela ku-1 iphuzu empeleni zilingana no-0.996264 amasentimitha .
Abadwebi bezithombe abasebenza ngamakhasimende ahlukahlukene bazothola ukuthi amanye amasentimitha asetshenziswayo futhi amanye asebenzisa i-picas, ngakho ukuqonda okuyisisekelo kokubili izinhlelo kuvela ngendlela efanele.
