I-Picas isetyenziselwa ukulinganisa ububanzi bekholomu kunye nobude
I-pica yiyunithi yefometting of measure eqhelekileyo isetyenziselwa ukulinganisa imigca yohlobo. Elinye i-pica lilingana namaqondo angama- 12, kwaye kukho i-picas e-6 kwi-intshi. Abenzi abaninzi bezobugcisa bedijithali basebenzisa iisentimitha njengendlela yokuzikhethela emsebenzini wabo, kodwa iipasta kunye namanqaku banamalungu amaninzi phakathi kwabathengisi be-typographers, i-typeetters kunye nabashicileli bezorhwebo.
Ubukhulu beCaa
Ubungakanani bephuzu kunye nepia zahluka kwii-18 neye-19. Nangona kunjalo, umgangatho osetyenziswayo e-US wasungulwa ngowe-1886. I-picas yaseMerika kunye nePostScript okanye i-picas yekhompyutyana isilinganisi esingu-0.166 intshi. Lo ngumlinganiselo we-pica osetyenziswe kwindlela yokucwangcisa imifanekiso yesimanje kunye nesofthiwe yesakhiwo sephepha.
Yintoni i-Pica esetyenziselwa yona?
Ngokuqhelekileyo, iipasta zisetyenziselwa ukulinganisa ububanzi kunye nobunzulu beentsika kunye nemida. Amaphutshana asetshenziselwa ukulinganisa izinto ezincinci kwiphepha elinjengehlobo kunye nokukhokela. Ngenxa yokuba iipasta kunye namaphuzu asetshenziswe kumaphephandaba amaninzi, unokufuna ukulungiselela izibhengezo kwiphepha lakho lephepha kwiipasta kunye namaphuzu.
Kwifayili yesakhiwo sephepha ezifana ne-Adobe InDesign ne-Quark Express, ileta p ichaza i-picas xa isetyenzisiweyo nge-numeral, njenge-22p okanye 6p. Ngamaqondo angama-12 kwi-pica, isiqingatha se-pica ngamanqaku angama-6 abhalwa njenge-0p6. Amanqaku asixhenxe abhaliweyo 1p5 (1 pica = amaphuzu ayi-12, kunye neengongoma ezi-5). Iiprogram zeendlela ezifanayo zibonelela ngamasentimitha kunye nezinye izilinganiso (amentimitha kunye nama-millimeters, nabani na?) Kubantu abangafuni ukusebenza kwiipasta kunye namaphuzu. Ukuguqulwa kwisofthiwe phakathi kweeyunithi zokulinganisa kukukhawuleza.
Kwi-CSS yewebhu, i-pica isicatshulwa yi-pc.
Ukuguqulelwa kwePica
1 intshi = 6p
1/2 intshi = 3p
1/4 intshi = 1p6 (1 pica kunye namanqaku angama-6)
1/8 intshi = 0p9 (zero picas kunye namanqaku a-9)
Ikholamu yesicatshulwa esiyi-2.25 intshi ububanzi buyi-13p6 ububanzi (i-picas 13 kunye namanqaku angama-6)
1 iphuzu = 1/72 intshi
1 pica = 1/6 intshi
Kutheni usebenzisa i-Picas?
Ukuba ukhululekile kunye nenkqubo enye yokulinganisa, akukho mfuneko yokukhawuleza ukutshintsha. Abaculi bezographic kunye nabachwepheli bee-typographer abaye bahlala ixesha elide babe ne-pica kunye neendlela ezijoliswe kuzo. Kulula kubo ukuba basebenze kwiipasta njengama-intshi. Kuya kufana okufanayo kubantu abaye kwishishini lephephandaba.
Abanye abantu bathi i-picas yinto elula ukuyisebenzisa kuba i-"base base 12" kwaye ihlukaniswe lula ngo-4, 3, 2 kunye no-6. Abanye abathandi ukusebenzisana nama-decimals okukhulayo ukususela kwinqanaba eli-1 ngokwenene lilingana ne-0.996264 intshi .
Abaculi begraphic abasebenzisana neentlobo ezahlukeneyo zabaxhasi baya kufumana ukuba ezinye iisentimitha zisebenzisa ezinye iispas, ngoko ke ukuqonda okuyisiseko kwezi zombini iinkqubo kuza ngokufanelekileyo.
