Isebenzisa futhi ilondoloze izithombe ze-GIF

Ngemuva kokudala opopayi e-Photoshop, udinga ukuyigcina kwelinye lamafomethi atholakalayo, elinye lakhona I-GIF. Isici sale fomethi ukuthi yenzelwe ukuboniswa (ukudlalwa kabusha) esipheqululini.

Uma unentshisekelo kwezinye izindlela zokonga izithombe, sincoma ukufunda le ndatshana:

Isifundo: Ungayigcina kanjani ividiyo ku-Photoshop

Inqubo yokudalwa I-GIF Ukugqwayiza kuchazwe kwesinye sezifundo ezedlule, futhi namhlanje sizokhuluma ngokuthi singalondolozwa kanjani ifayela ngefomethi I-GIF kanye nezilungiselelo zokusebenziseka kahle.

Isifundo: Dala izithombe ezilula e-Photoshop

Ukulondolozwa kwe-GIF

Okokuqala, masiphinde okuqukethwe futhi ujwayele iwindi lezilungiselelo zokulondolozwa. Ivula ngokuchofoza entweni. Gcina i-Web kumenyu Ifayela.

Iwindi liqukethe izingxenye ezimbili: ibhulokhi yokubuka kuqala

kanye nezilungiselelo block.

Ukubuka kuqala

Ukukhetha kwenombolo yezinketho zokubuka kukhethwe phezulu kwe-block. Ngokuya ngezidingo zakho, ungakhetha isilungiselelo osifunayo.

Isithombe efasiteleni ngalinye, ngaphandle kwasekuqaleni, sakhiwe ngokwahlukile. Lokhu kwenziwa ukuze ukhethe ukukhetha okuhle kakhulu.

Engxenyeni ephezulu kwesobunxele yebhuloki kusethi encane yamathuluzi. Sizosebenzisa kuphela "Isandla" futhi "Isikali".

Nge Izandla Ungahambisa isithombe ngaphakathi kwewindi elikhethiwe. Ukukhetha kwenziwa futhi ngaleli thuluzi. "Isikali" wenza isenzo esifanayo. Ungasondeza futhi uphume nezinkinobho ezansi kwebhulokhi.

Ngezansi kunombhalo obhalwe phansi Buka. Ivula inketho ekhethiwe esipheqululini esizenzakalelayo.

Ewindini lesiphequluli, ngaphezu kweqoqo lamapharamitha, singathola futhi Ikhodi ye-HTML Ama-GIF

Izilungiselelo block

Kulesi bhulokhi, amapharamitha wesithombe ayaguqulwa, sizocubungula kabanzi.

1. Isikimu sombala. Lokhu kulungiselelwa kunquma ukuthi iyiphi itafula lombala eliyi-indexed elizosetshenziswa esithombeni ngesikhathi sokwenza kahle.

   

   • I-Perceptual, kepha "uhlelo lokuqonda." Uma isetshenziswa, i-Photoshop yakha itafula lombala, iqondiswa yimibala yamanje yesithombe. Ngokusho kwabathuthukisi, leli tafula lisondele ngangokunokwenzeka ngendlela iso lomuntu elibona ngayo imibala. Futhi - isithombe esiseduze nokwangempela, imibala igcinwa kakhulu.
   • Ukukhetha Isikimu sifana nesangaphambilini, kepha ikakhulukazi sisebenzisa imibala ephephile kuwebhu. Kukhona futhi ukugcizelela ekubonisweni kwama-shades asondele kokwasekuqaleni.
   • Adaptive. Kulokhu, itafula lakhiwa ngemibala evame kakhulu esithombeni.
   • Kunomkhawulo. Inemibala engama-77, eminye yayo eshintshwa ngamhlophe ngesimo sedothi (okusanhlamvu).
   • Isiko. Lapho ukhetha lolu hlelo, kungenzeka ukudala iphalethi lakho.
   • Mnyama nomhlophe. Kusetshenziswa imibala emibili kuphela kuleli tafula (elimnyama nelimhlophe), futhi besebenzisa usayizi wokusanhlamvu.
   • Ku-grayscale. Kunezindlela ezahlukahlukene ezingama-84 zama-shades of grey lapha.
   • IMacOS futhi IWindows. Lawa matafula ahlanganiswa ngokususelwa kuzici zokubonisa izithombe kwiziphequluli ezisebenzisa lezi zinhlelo zokusebenza.

   Nazi izibonelo ezimbalwa zokusetshenziswa kwesekethe.

   

   Njengoba ubona, amasampula amathathu okuqala ayikhwalithi eyamukelekayo. Naphezu kweqiniso lokuthi ngumbono cishe awufani komunye nomunye, lezi zinhlelo zizosebenza ngokuhlukile kuzithombe ezihlukile.

2. Inani eliphezulu lemibala etafuleni lemibala.

   

   Inani lamathunzi asesithombeni lithinta ngqo isisindo salo, futhi ngenxa yalokho, isivinini sokulanda esipheqululini. Inani elisetshenziswa kakhulu 128, ngoba ukulungiselelwa okunjalo cishe akunamphumela kwikhwalithi, ngenkathi kunciphisa isisindo se-gif.

   

3. Imibala yeWebhu. Lokhu kulungiselelwa kusetha ukubekezelela okuthi izithunzi ziguqulwe zilingane kusuka kubhokisi lephephile leWebhu. Isisindo sefayela sinqunywa yinani elisethwe yisilayidi: inani liphakeme - ifayela lincane. Lapho usetha imibala yeWebhu, ungakhohlwa ngekhwalithi nayo.

   

   Isibonelo:

   

4. Ukuyekelela kukwenza uvumelanise ushintsho phakathi kwemibala ngokuxuba izithunzi eziqukethwe etafuleni lokufaka le-index ekhethiwe.

   

   Futhi, ukulungiswa kuzosiza, ngangokunokwenzeka, ukulondolozwa kwama-gradients kanye nokuthembeka kwezigaba ze-monophonic. Lapho ukusikwa kufakwa, isisindo sefayela siyakhuphuka.

   Isibonelo:

   

5. Ukusobala Isimo I-GIF isekela amaphikseli we-opaque asobala ngokuphelele noma ngokuphelele.

   

   Le pharamitha, ngaphandle kokulungiswa okwengeziwe, ibukisa kabi imigqa egobile, ishiye imiyalo ye-pixel.

   

   Ukuhleleka okuhle kubizwa "Math" (kwezinye izinhlelo "Umngcele") Ngosizo lwayo, ukuxuba amaphikseli wesithombe nesizinda sekhasi elizotholakala kulo kulungiselelwe. Esibonisweni esihle kakhulu, khetha umbala ofanelana nombala wesizinda sendawo.

   

6. Ihlanganisiwe. Enye yezinto eziwusizo kakhulu kuzilungiselelo zeWebhu. Uma kunjalo, uma ifayela linesisindo esibalulekile, likuvumela ukuthi usikhombise ngokushesha isithombe ekhasini, sithuthukise ikhwalithi yaso njengoba ilayisha.

   

7. Ukuguqulwa kwe-sRGB kusiza ukugcina ubuningi bemibala yezithombe zokuqala ngenkathi igcinwa.

   

Ukwenza ngokwezifiso "Ukufiswa kokusobala" ilulaza kakhulu ikhwalithi yesithombe, futhi mayelana nepharamitha "Ukulahleka" sizokhuluma engxenyeni esebenzayo yesifundo.

Ukuqonda okungcono kwenqubo yokusetha ukulondolozwa kwe-GIF e-Photoshop, udinga ukuzijayeza.

Prakthiza

Umgomo wokwenza kahle izithombe ze-Intanethi ukunciphisa isisindo sefayela ngenkathi kugcinwa ikhwalithi.

1. Ngemuva kokucubungula isithombe, iya kumenyu Ifayela - Gcina i-Web.
2. Sisetha imodi yokubuka "Izinketho ezi-4".

   

3. Okulandelayo, udinga ukwenza okukodwa kokunye okufana nokwangempela ngangokunokwenzeka. Akube isithombe ngakwesokudla komthombo. Lokhu kwenziwa ukuze kulinganiswe usayizi wefayela ngekhwalithi ephezulu.

   Izilungiselelo zepharamitha zingokulandelayo:

   • Isikimu sombala "Ukukhetha".
   • "Imibala" - 265.
   • Ukushona - "Okungahleliwe", 100 %.
   • Sisusa umucu phambi kwepharamitha Ihlanganisiwe, ngoba ivolumu lokugcina lesithombe lizoba lincane impela.
   • Imibala yeWebhu futhi "Ukulahleka" - zero.

     

   Qhathanisa umphumela nokwasekuqaleni. Engxenyeni engezansi yewindows nesampula, singabona usayizi wamanje we-GIF nesivinini sayo sokulanda ngejubane le-Intanethi elibonisiwe.

   

4. Iya esithombeni esingezansi nje esilungiselelwe. Masizame ukukwengeza.
   • Sishiya isikimu singashintshiwe.
   • Inombolo yemibala incishiswa ibe yi-128.
   • Inani Ukushona yehle yaya kuma-90%.
   • Imibala yeWebhu asithinti, ngoba kulokhu ngeke kusisize ukugcina ikhwalithi.

     

   Usayizi we-GIF wehle ukusuka ku-36.59 KB kuya ku-26.85 KB.

   

5. Njengoba isithombe sesivele sinezimpawu ezithile zokusanhlamvu kanye nezinkinga ezincane, sizozama ukwanda "Ukulahleka". Le pharamitha ichaza izinga elamukelekayo lokulahleka kwedatha ngesikhathi sokucindezela. I-GIF. Shintsha inani libe ngu-8.

   

   Sikwazile ukuqhubekisa ukunciphisa usayizi wefayela, ngenkathi silahlekelwa yikhwalithi encane. Ama-GIF manje anesisindo esingu-25,9 kilobytes.

   

   Sekukonke, sikwazile ukunciphisa usayizi wesithombe cishe nge-10 KB, okungaphezu kwama-30%. Umphumela omuhle kakhulu.

6. Izenzo ezengeziwe zilula kakhulu. Chofoza inkinobho Gcina.

   

   Khetha indawo ongayigcina, unikeze igama lesipho, bese uphinde uqhafaze "Gcina ".

   

   Sicela wazi ukuthi kungenzeka ukuthi kukhona I-GIF dala futhi HTML idokhumenti lapho isithombe sethu sizongeniswa khona. Ukuze wenze lokhu, kungcono ukhethe ifolda engenalutho.

   

   Njengomphumela, sithola ikhasi nefolda enesithombe.

   

Ithiphu: lapho uqamba igama, zama ukungasebenzisi izinhlamvu zesiCyrillic, ngoba akuzona zonke iziphequluli ezikwazi ukuzifunda.

Lesi isifundo sokugcina isithombe ngesakhiwo I-GIF kuqediwe. Kuyo sithole ukuthi ungalikhulisa kanjani ifayela ukuze lithunyelwe kwi-Intanethi.
