GIF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni i-GIF?

I-GIF yifomati yomfanekiso we-raster engenakulahleka egcina yonke i-pixel ngaphandle koxinzelelo lwezinto ezibonakalayo. I-GIF ilungele kakhulu imifanekiso eqingqiweyo, umzobo womgca, imifanekiso engumzobo enemiphetho eqinileyo nanoma yiphi na imifanekiso enokuthi iguqulwe kancinane.

Ingaba uopopayi uyaphila xa ndiguqula i GIF?

Ixhomekeke ngokupheleleyo kwinjongo. Guqula kwifomati enye ekwaziyo uopopayi kwaye ii-frames kunye nexesha lihamba; guqula kwifomati ehlalayo kwaye ufumane i-frame enye, ngokuqhelekileyo i-first. Enye indlela ibalulekile ngakumbi kwinkqubo: uopopayi GIF oguqulwe kwividiyo eyiyo uhlala ujikeleza ubungakanani kwixabiso elingcono, kuba ii-codecs zevidiyo zicofa intshukumo ngokuchanekileyo kwaye le fomati ayisebenzi. I-GIF's 256-imibala ye-ceiling ilahla i-gradients kunye nevidiyo ehlala, kwaye ubungakanani befayili yayo yobuchule bunomlinganiselo onzima kune-WebP okanye i-MP4.

Ingaba kukho into elahlekile xa i GIF iguqulwa ibe yifomati enye engalahlekiyo?

Akukho data ye-pixel. GIF igcina umfanekiso ngokuchanekileyo kunokuba ilinganise, ngoko uguqulelo phakathi kwefomati ezimbini ezingalahlekiyo luyabuyiselwa kwaye luyaphinda kungekho xesha lide ngaphandle kokulahleka. Okunokuphelelwa yinto yonke ejikeleze ii-pixels - iiprofayili zombala, ukuqaqamba, udweliso, i-metadata efakwe ngaphakathi - kuba inkxaso yazo itshintsha kakhulu phakathi kwefomati kunendawo yokugcina i-pixel. I-GIF ayilahleki kodwa iphele kwi-256-imibala yengqokelela yezixhobo ngesakhelo ngasinye, isebenzisa uxinzelelo lwe-LZW kunye nokukhanya okubini kombala omnye.

Kutheni i-web inikezelwa njenge GIF?

Kuba yakhiwa ngokuchanekileyo kulo msebenzi: iifayile ezincinci, iqala ngokukhawuleza, akukho plugin kwaye akukho layisenisi yokukhathazeka ngayo. Oku kwenza ukuba igqibelele ekunikezeleni kwaye ingaphawulwanga nantoni na enye - iisixhobo zokuhlela, ii galleries zefowuni kunye neesixhobo ezidala zihlala ziyihoyi. Ukuguqula kwifomati yomsebenzi oqhelekileyo yenza ukuba imixholo elayishwe ezantsi isebenziseke ngaphandle kwe web. Umfanekiso ojikelezayo we GIF udlala ngokucacileyo naphi na - abaxhasi be-imeyili, iiforums, iinkqubo zokuncokola kunye neebrowser zonke ziyibonisa ngaphandle konxibelelwano lwe-codec.

Ingaba i-GIF igcina isiqalo esicacileyo?

Ewe - ifomati igcina isiqhagamshelanisi se-alpha, ngoko ilogo ecutiweyo, imifanekiso yemveliso kunye nokugqitywa gcina ukubonakala kwabo endaweni yokufika kwi-rectangle emnyama. Ukutshintsha kwifomati engenayo i-alpha kulapho i-alpha ihamba khona kakubi: iindawo ezibonakalayo zigqityiwe ngombala oqinileyo, ngokuqhelekileyo omnyama okanye omnyama, kwaye akukho ndlela yokubuyela umva efutshane yokufihla umxholo kwakhona.

Ingaba kubaluleke na ukuba u GIF uneminyaka engaphezu kweeminyaka ezimashumi amathathu ubudala?

Ubudala ngokwalo alukuyingxaki - iifomati ezininzi ezivela kulo nyaka zihlala zilungile, ngokucacileyo ngenxa yokuba konke kwakuba neminyaka emininzi yokuzisebenzisa. Okubalulekileyo kulapho ixesha licinga khona: iifayile ezincinci, abaqhubi abancinci, akukho msebenzi womnatha, kunye neempawu ezingafunekiyo. Apho ezi zinto zicinga khona, ifomati ilungile. Apho azisebenzi, le yisizathu sokuguqula. I-GIF yifomati ye-CompuServe ye-1987, kwaye isizathu esifanayo esiphilayo kukuba ibonisa ubugcisa.

Ndingasebenzisa i-GIF ngokuthe ngqo kwiphepha le-web?

Ewe - yonke ibrowser yangoku iyenza ngokusemthethweni, ngoko ayifunanga ukopi ozakubuyela umva nokuguqulela ngexesha lokushicilela. Umbuzo osele ukhona ubunzima kunokuba uxhaso: umfanekiso ofanayo kwifomati ye web ekutsha ihlala ikwishumi elinesibini yobungakanani kwifomati ebonakalayo yomgangatho, efanele ukwenziwa nantoni na ebonakala ngapha kweqokobhe.

Ubani olawula ifomati GIF?

Akukho mntu, kwaye loo nto yinjongo yayo. Ulwazi oluthe kratya luza kufumaneka kumazwe, wonke umntu angalisebenzisa ngaphandle kokucela okanye ukuhlawula, kwaye akukho nkampani ingatshintsha iimeko kamva - oko kukuthi, iincwadi, iindidi zezinto eziqhelekileyo kunye nemibutho yomphakathi ichaza ifomati njengele nto nayiphi na into ekufuneka ivuleke kwiminyaka emibini. Urhwebo aluhambelani, olulugqibeleleyo; kukuba akukho mnikeli oza kuqhagamshelana naye xa ezinye izixhobo zisebenzisa inkcukacha ezimbi.

Ndimele ndiguqule njani i-GIF ibe yifomati enye?

Guqula i-GIF ibe yi-JPG okanye i-WebP xa injongo ikwimeko-bume yokuvula i-web okanye i-imeyili, apho ubungakanani befayili obuncinci bubalulekile ngakumbi kune-pixel nganye yobuxoki.

Ingaba ukujika i-GIF kuya kunyusa ubunjani bomfanekiso?

Xa uguqula i-GIF ibe yifomati engalahlekiyo, ii-pixels zigcinwa ngokuchanekileyo. Xa uguqula i-GIF ibe yifomati elahlekiyo njenge-JPG, i-encoder isenza umgangatho-vs-ubungakanani be-trade-offs olawula ngazo nge-output quality setting.
