Indlela Yokunciphisa Usayizi Wefayela We-GIF Wokusebenza Kwe-Web Site Engcono

I- GIF ephansi yenza ubuyekeze ngoba nje ngokusetshenziswa okwandayo kwama-smartphones nabasebenzisi bokulinganiselwa be-bandwidth sebezilindele izikhathi ezifakiwe zokulayisha ngokushesha. Izithombe ezincane zakho zewebhu, izithombe zakho ngokushesha zizolayisha futhi izivakashi zakho zizojabula kakhulu. Ngaphezu kwalokho, amawebhusayithi amaningi anemikhawulo ngobukhulu bezikhangiso.

I-GIF Izithombe neWebhu

Izithombe ze-GIF akufanele zithathwe njengezinga elilodwa elihambisana nesixazululo. Izithombe ze-GIF zinemibala engu-256 eningi, okusho ukuthi ungalindela isithombe esibucayi nokonakala kombala uma ungaqapheli. Ifomethi yefayili ye-GIF, ngezindlela eziningi, ifomethi yefa elibuyela emuva ezinsukwini zokuqala zewebhu. Ngaphambi kokwethulwa kwefomethi ye-GIF, izithombe zewebhu zazimnyama futhi zimhlophe futhi zicindezelwe ngokusebenzisa ifomethi ye-RLE. Baqale bavele endaweni yesehlakalo ngo-1987 ngenkathi i-Compuserve ikhishwe ifomethi njengesisombululo se-imaging web. Ngaleso sikhathi, umbala wawusanda kuvela kwideskithophu futhi iwebhu yayifinyeleleke nge-modems exhunywe kumgqeni wefoni. Lokhu kudalwe isidingo somfomethi wesithombe owagcina izithombe ezincane ngokwanele ukuba zithunyelwe, ngokusebenzisa umugqa wefoni, kwisiphequluli sewebhu ngokulandelana okufutshane.

Izithombe ze-GIF zilungele ihluzo ezihlosiwe ngokucacile nomdwebo ongenqamuleli wombala, njenge-logo noma umdwebo womugqa. Nakuba zingasetshenziselwa izithombe umbala we-palette onciphise uzokwethula izinto zokusebenza emfanekisweni. Noma kunjalo, ukunyakaza kobuciko be-Glitch nokuphakama kwe-cinemagraph kuye kwaveza isithakazelo esivuselelwe kwifomethi ye-GIF.

Indlela Yokunciphisa Ubunikazi befayela le-GIF for Better Web Site Performance

Lezi zeluleko zizokusiza wenze ama-GIF akho abe mncane ngangokunokwenzeka.

1. Khipha noma yimuphi isikhala esingaphezulu kwesithombe. Ukunciphisa ubukhulu be-pixel yesithombe sakho kuyindlela eyodwa ephumelela kakhulu yokunciphisa usayizi wefayela. Uma usebenzisa i-Photoshop, umyalo we-Trim usebenza kahle ngalokhu.
2. Uma ulungisa isithombe se-gif, ungase uthande ukunciphisa ubukhulu bokukhipha.
3. Nciphisa inombolo yemibala esithombeni.
4. Ama-GIF ama-animated, nciphisa inani lamafomu esithombeni.
5. Uma usebenzisa i-Photoshop CC 2017, ungakha ifayela le-GIF ngokusebenzisa i-Export As item item. Khetha ifayela> Thumela njenge ... futhi uma imenyu ivula, khetha i-GIF njengefomethi yefayela bese unciphisa ubukhulu bomzimba (Ububanzi nobukhulu) besithombe.
6. Uma usebenzisa i-Adobe Photoshop Elements 14, khetha Ifayela> Londoloza iwebhu. Lokhu kuzovula ibhokisi lengxoxo ye-Inthanethi Yokulondolozwa elitholakala ku-Adobe Photoshop CC 2017, Ifayela> Thumela> Gcina IWebhu (Ifa) . Uma ivula ungafaka isicelo sokungena, sinciphisa umbala nobukhulu bomzimba wesithombe.
7. Gwema ukufika. I-Dithering ingenza ezinye izithombe zibukeke zingcono, kodwa izokwengeza usayizi wefayela. Uma ngabe isofthiwe yakho ikuvumela, sebenzisa izinga elingaphansi lokwehla ukuze ulondoloze ama-byte engeziwe.

1. Elinye isofthiwe ine-"yokulahlekelwa" inketho yokugcina ama-GIF. Lolu khetho lunganciphisa kakhulu usayizi wefayela, kodwa linciphisa ikhwalithi yesithombe.
2. Ungasebenzisi ukusetshenziswa kwe-interlacing. Ukuphenya ngokuvamile kuvusa usayizi wefayela.
3. Kokubili i-Photoshop ne-Photoshop Elements kuzokubonisa isikhathi sokulanda. Ungakunaki. Isekelwe ekusetshenzisweni kwe modem engu 56k. Inombolo evumelekile ngaphezulu izovela uma ukhetha i-modem yekhebula kusuka kwimenyu ehlaselwa phansi.

Amathiphu:

1. Gwema izithombe ezingenasidingo. Izithombe ezidluleleko azigcini nje ekungenizeni isikhathi sokulanda ikhasi lakho lewebhu, kepha abasebenzisi abaningi bakuthola ukuphazamisa.
2. Izithombe ze-GIF ezinamabhuloki amakhulu wombala oqinile namaphethini angaphezulu zicindezela kangcono kunezithombe ezinemibala embala, izithunzi ezithambile, namaphethini aqondile.
3. Uma unciphisa imibala kuma-GIF, uzothola ukucindezelwa okungcono uma imibala yenombolo isethwe kuncane kunazo zonke kulezi zikhetho: 2, 4, 8, 16, 32, 64, 128, noma 256.
