GIF Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni ifayili GIF?

I-GIF (iFomathi yokuTshintshiselana ngeMifanekiso) yifomathi yomfanekiso we-bitmap exhasa upopayi kunye nemibala engaphezulu kwama-256.

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 layisensi 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.

Kutheni imizuzwana emininzi yoopopayi GIF ifana nefayili enkulu?

Kuba igcina iframes, hayi intshukumo. Iframe nganye icinezelwe ngokwayo ngaphandle kokubonisana nenye phambi kwayo, ngoko ke iclip efutshane ivela kwimifanekiso epheleleyo emininzi kumgca kwaye ifayile iqhuba kwi megabytes. Ividiyo codec ikhowudi utshintsho phakathi kweeframes endaweni yoko iwela kwifomathi efanayo kwinxalenye yobungakanani, oko kukuthi, ukuguqula udweliso lwemifanekiso kwividiyo kulungiso oluqhelekileyo lwephepha elalayisha ngokukhawuleza.

Kutheni iithayile ezihamba ngaphaya zibonakala zibanda kwi GIF?

Kuba umbala uvela kwingqokelela yezixhobo ekhoyo njengesalathisi kunokuba ube simahla. Ipixel nganye ibonisa ukungena kwitheyibhile encinci, ngoko izulu eliqala ngezigidi zemibala licinezelwe kwishumi elinesithathu lezigidi kwaye iincopho phakathi kwazo zibonisa njengezibhanti. Ukutyhila ifihla ngexabiso lombala othambileyo. Ukuguqula kwifomati yombala opheleleyo ususa umphezulu, kodwa ayikwazi ukuvelisa kwakhona imibala eyandisiweyo.

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 ixesha lesakhelo kunye nokuphindaphinda zihlala ziguqula i GIF?

Kwifomati enye ekwaziyo uopopayi, ewe - i-frame nganye i-delay kunye nenani le-loop ligcinwa kwifayili kwaye lithunyelwe. Kwifomati ehlala ikhona i-frame enye kuphela ehlala, ngokuqhelekileyo i-first. Kwividiyo i-loop flag ayinakho ukuya naphi na, kuba umdlali ugqiba ukuba uyaphinda. Khangela ukudlala ngokukhawuleza emva kokuba i-frame rate itshintshile: i-rate ethe nkqo ingalinganisi kuphela i-frame nganye eguqukayo i-delay.

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, ekufuneka yenziwe 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 emva koko - oko kukuthi, iincwadi zokugcina, 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.

Ndingayinika kwakhona igama elipheleleyo lesiqendu endaweni yokuguqula i GIF?

Akukho nanye, kwaye ifanele ukuqonda kutheni: unikezelo luphawu, ngelixa i bytes ngaphakathi zidityaniswe kwifomati ekhethekileyo. Ukuphinda ubize ifayile ivelisa ifayile igama layo lithembisa into imixholo yayo ayinikezeli, kwaye nantoni na evula ifayile okanye ilahlekile ifayile okanye ifunda ngokungachanekanga. Ukuphela kwendlela efutshane kuhlobo olubini oluyinyani ibhokisi efanayo phantsi kwegama elahlukileyo - kwaye nalapho ukuphinda ubhale ngokuchanekileyo kukhuselekile kunegama elahlukileyo.
