Kugeza ubu, mubuhanga bwo gucunga amabara, ibyo bita ibara biranga umwanya uhuza ikoresha umwanya wa chromaticity ya CIE1976Lab. Amabara ku gikoresho icyo aricyo cyose arashobora guhindurwa kuri uyu mwanya kugirango akore uburyo bwo gusobanura "rusange", hanyuma guhuza ibara no guhinduka birakorwa. Muri sisitemu y'imikorere ya mudasobwa, umurimo wo gushyira mu bikorwa ibara rihuza ibara ryuzuzwa na "ibara rihuza ibara", rifite akamaro gakomeye kubwizerwa bwo guhindura amabara no guhuza amabara. None, nigute dushobora kugera ku ihererekanyabubasha mu mwanya wamabara "rusange", ukagera kubutaka butagira igihombo cyangwa gito?
Ibi bisaba buri gikoresho cyibikoresho kugirango habeho umwirondoro, ariryo fayili yibara ryibikoresho.
Turabizi ko ibikoresho, ibikoresho, nibikorwa bitandukanye biranga ibintu bitandukanye mugihe cyo kwerekana no kohereza amabara. Mu micungire yamabara, kugirango twerekane amabara yerekanwe ku gikoresho kimwe hamwe n'ubudahemuka bukabije ku kindi gikoresho, tugomba gusobanukirwa ibara ryerekana ibara ryerekana amabara kubikoresho bitandukanye.
Kuva igikoresho cyigenga cyibara ryigenga, CIE1976Lab chromaticity space, yaratoranijwe, ibiranga ibara ryigikoresho bigaragazwa ninzandiko zandikirwa hagati yibisobanuro byigikoresho nigiciro cya chromaticité yumwanya wibara rya "rusange", aribwo buryo bwo gusobanura ibara ryibikoresho .
1. Ibikoresho byamabara biranga dosiye
Muri tekinoroji yo gucunga amabara, ubwoko bwibikoresho byibikoresho biranga dosiye ni:
Ubwoko bwa mbere ni scaneri iranga dosiye, itanga inyandiko zandikishijwe intoki ziva mu masosiyete ya Kodak, Agfa, na Fuji, kimwe namakuru asanzwe kuri ziriya nyandiko. Izi nyandiko zandikishijwe intoki zinjijwe hakoreshejwe scaneri, kandi itandukaniro riri hagati yamakuru yabikijwe hamwe namakuru asanzwe yandikishijwe intoki yerekana ibiranga scaneri;
Ubwoko bwa kabiri nubwoko bwa dosiye yerekana, itanga porogaramu zimwe zishobora gupima ubushyuhe bwamabara yerekana, hanyuma ikabyara ibara kuri ecran, ryerekana ibiranga kwerekana; Ubwoko bwa gatatu ni dosiye iranga ibikoresho byo gucapa, nayo itanga urutonde rwa software. Porogaramu itanga igishushanyo kirimo amagana y'amabara muri mudasobwa, hanyuma igasohora igishushanyo ku gikoresho gisohoka. Niba ari printer, irerekana neza, kandi imashini icapa ibanza gukora firime, ingero, hamwe nicapiro. Ibipimo by'aya mashusho asohoka byerekana ibiranga dosiye amakuru y'ibikoresho byo gucapa.
Umwirondoro wakozwe, uzwi kandi nka dosiye iranga ibara, igizwe nuburyo butatu bwingenzi: umutwe wamadosiye, imbonerahamwe yumurongo, hamwe namakuru yibintu.
·Umutwe wa dosiye: Irimo amakuru yibanze yerekeye ibara ryiranga dosiye, nkubunini bwa dosiye, ubwoko bwuburyo bwo gucunga amabara, verisiyo yimiterere ya dosiye, ubwoko bwibikoresho, umwanya wibara ryibikoresho, umwanya wamabara yibiranga dosiye, sisitemu y'imikorere, uwakoze ibikoresho , intego yo kugarura amabara, itangazamakuru ryumwimerere, urumuri rwamabara yamakuru, nibindi. Umutwe wa dosiye utwaye byose hamwe 128 bytes.
· Tag Imbonerahamwe: Irimo amakuru ajyanye nizina ryumubare, aho ubikwa, nubunini bwamakuru ya tagi, ariko ntabwo ikubiyemo ibintu byihariye biranga. Ingano yizina ryibirango ifata 4 bytes, mugihe buri kintu kiri mumeza yikimenyetso gifite 12 bytes.
·Markup element element data: Irabika amakuru atandukanye asabwa mugucunga amabara ahantu hagenwe ukurikije amabwiriza ari kumeza yerekana ibimenyetso, kandi biratandukana bitewe nuburemere bwamakuru yerekana ibimenyetso hamwe nubunini bwamakuru yanditseho.
Kubara ibara ryamadosiye yibikoresho mubucuruzi bwo gucapa, abakora amashusho no gutunganya amakuru bafite inzira ebyiri zo kubibona:
·Uburyo bwa mbere: Iyo uguze ibikoresho, uwabikoze atanga umwirondoro hamwe nibikoresho, bishobora kuzuza ibisabwa muri rusange gucunga ibikoresho. Iyo ushyizeho porogaramu isaba ibikoresho, umwirondoro winjizwa muri sisitemu.
·Uburyo bwa kabiri nugukoresha porogaramu yihariye yo gukora umwirondoro kugirango ubyare amabara akwiye asobanura amadosiye ashingiye kumiterere nyayo yibikoresho bihari. Iyi dosiye yakozwe mubisanzwe irasobanutse neza kandi ijyanye numukoresha nyirizina. Bitewe nimpinduka cyangwa gutandukana muburyo bwibikoresho, ibikoresho, nibikorwa mugihe. Kubwibyo, birakenewe gusubiramo umwirondoro mugihe gisanzwe kugirango uhuze nibisubizo byamabara muricyo gihe.
2. Kohereza amabara mubikoresho
Noneho, reka turebe uko amabara yoherezwa mubikoresho bitandukanye.
Ubwa mbere, kubwinyandiko ifite amabara asanzwe, scaneri ikoreshwa mugusikana no kuyinjiza. Bitewe numwirondoro wa scaneri, itanga isano ijyanye nibara (ni ukuvuga umutuku, icyatsi, nubururu bwa tristimulus) kuri scaneri kugeza kuri CIE1976Lab ya chromaticity. Kubwibyo, sisitemu y'imikorere irashobora kubona chromaticity agaciro Lab yibara ryumwimerere ukurikije iyi sano ihinduka.
Ishusho ya skaneri irerekanwa kuri ecran yerekana. Kubera ko sisitemu yamenyereye kwandikirana hagati ya Lab chromaticity indangagaciro hamwe nibimenyetso bitukura, icyatsi, nubururu byerekana ibinyabiziga, ntabwo ari ngombwa gukoresha mu buryo butaziguye indangagaciro zitukura, icyatsi, nubururu bwa chromaticity ya scaneri mugihe cyo kwerekana. Ahubwo, uhereye kuri Lab chromaticity indangagaciro zandikishijwe intoki zabanjirije iyi, ukurikije isano yo guhindura itangwa nu mwirondoro werekana, ibimenyetso byerekana ibinyabiziga bitukura byerekana ibara ritukura, icyatsi, nubururu bishobora kwerekana neza ibara ryumwimerere kuri ecran birabonetse, Twara kwerekana Kuri Kugaragaza Amabara. Ibi byemeza ko ibara ryerekanwe kuri monite rihuye nibara ryumwimerere.
Nyuma yo kwitegereza neza ibara ryerekana ishusho, uyikoresha arashobora guhindura ishusho ukurikije ibara rya ecran ukurikije ibyo umukiriya asabwa. Byongeye kandi, bitewe numwirondoro urimo ibikoresho byo gucapa, ibara ryukuri nyuma yo gucapa rirashobora kugaragara kumurongo nyuma yo gutandukanya ibara ryamashusho. Nyuma yuko umukoresha anyuzwe nibara ryishusho, ishusho ni ibara ryatandukanijwe kandi ribitswe. Mugihe cyo gutandukanya amabara, ijanisha ryukuri ryududomo riboneka hashingiwe ku isano yo guhindura amabara itwarwa numwirondoro wigikoresho cyo gucapa. Nyuma yo gukorerwa RIP (Raster Image Processor), gufata amajwi no gucapa, gucapa, kwerekana, no gucapa, kopi yacapwe yinyandiko yumwimerere irashobora kuboneka, bityo ikarangiza inzira yose.
