Format Graphic. -JPEG, GIF ne-PNG - okuvame kakhulu ihluzo ifomethi

Ethandwa kakhulu amafomethi image, ezibhekene abasebenzisa i-Internet --JPEG, GIF, ne-PNG. Ake sixoxe izici ngamunye wabo, sikunikeza incazelo emfushane futhi libalule. Asihambe nathi kanjani ungakwazi ngokushesha kabusha format izithombe izinhlelo ezihlukahlukene ngisho abahleli ingcaca, njengoba akuzona zonke kudivayisi Ungafunda entsha noma ngaphansi ezivamile amafomethi image.

Kuyini a ihluzo format?

Okokuqala ake ukusho amazwi ambalwa mayelana nomqondo format sokuqhafaza, ukuze senze kube sobala ukuthi kuyini ukuthi sisebenzelana nabantu. Lenchazelo kusho indlela wesitoreji kolwazi sokuqhafaza, okungukuthi zonke izinhlobo imifanekiso nezithombe. format ngamunye sokuqhafaza has izindlela yayo, izici ububanzi. Kuye lokhu, isithombe esifanayo kokuba isandiso ezahlukene, ungase ube usayizi ezahlukene, umbala ukujula, izici ukusetshenziswa.

Ukwabela raster, vector, ngisho nezakhiwo eziyinkimbinkimbi. Kodwa kulesi sihloko sizoxoxa kuphela mayelana bitmap ihluzo futhi kanjani ukugcina ke, ngoba iningi labazalwane amafayela isandiso elikhombisa isithombe fanele ngokuqondile kulo.

JPEG - ubudala nokunokwethenjelwa

Asiqale ekunwetshweni ethandwa kakhulu kuyo yonke indawo. Ngakho, Ifomethi yefayela JPEG (okuyilona elisebenzayo futhi wabonisa esebenzisa okunye ukwehliswa kwezintela --JPG) izikhala ezivamile-Inthanethi avame. Khumbula, ngisho izithombe zakho ithathwe ku- ikhamera noma iselula kuyinto .jpeg isandiso.

Le fomethi kabanzi indlela esetshenziswa ngoba isithombe kokucindezelwa, okuyinto ngezinye izikhathi kuthinta iqophelo izithombe. He is zithandwa, naphezu kweqiniso lokuthi ilayisensi liyadingeka ukusetshenziswa kwaso. Ukujula umbala 24 izingcezu.

I-GIF - eyenzelwe isitoreji images hhayi kuphela

Ngakho, kokubukeza nawe ifomethi ye-JPEG, kufanele nazo ziyakhuluma yesibili ethandwa kakhulu - i-GIF. Yena - omunye endala kakhulu emhlabeni ihluzo raster. Iphinde isetshenziselwe ngokwabelana izithombe nge-Internet, ikakhulukazi - e-mail. Kokucindezela kwenzeka ngaphandle kokulahleka izinga, bese umbala 8 izingcezu ukujula. Isekela hhayi kuphela obala, kodwa futhi izithombe.

Kuwufanele wazi ukuthi uma ukuguqulela umphumela wokugqwayiza kulahleka Yiqiniso, uma ukhetha ifomethi yefayela ayisekeli ke.

-PNG-GIF njengoba Analogue entsha

Saxoxa nawe JPEG ne-GIF format, kodwa manje ake sixoxe PNG. abasebenzisi zakhe eziningi Inthanethi ngokuthi inguqulo ethuthukisiwe ye-GIF. Isizathu salokhu ukuthi kusekelwe izindlela ezifanayo wesitoreji, njengoba amafayela ne .gif isandiso. Ngokushesha ukhumbule ukuthi, ngokungafani esasisandulele, akudingi ilayisensi, okuyinto ebalulekile.

Lapho ukugxisha ulwazi, ikhwalithi yesithombe akusho, ngoba ngefomethi odlule. Kulokhu, umehluko oyinhloko ukuthi ikuvumela ukuthi usebenzise inombolo engenamkhawulo imibala. Kufanele kuqashelwe ukuthi ukujula umbala lingafika ku-48 izingcezu. Ngenxa yokuthi ifomethi kuyinto empeleni esasisesisha, uye Awukatholi ukuthandwa umhlaba, kodwa manje ingatholakala kuyi-Internet.

Indlela ukuguqula umdwebo? Uhlelo ukushintsha isandiso

Ngakho, thina adiliza-JPEG, GIF ne-PNG - izandiso ezivamile ekhombisa bitmap ihluzo. Manje ake sixoxe indlela ifomethi isithombe.

Ngezinye izikhathi kufanele ukubhekana nenkinga enjalo, isiphequluli, hlelo, idivayisi ayisekeli ifayela extension ethile, ikakhulukazi uma idivayisi ubudala, futhi ifomethi kungenazo entsha. Ezimweni ezinjalo kukhona isidingo ukukubika isithombe. Indlela ukuxazulula le nkinga ngokushesha ngangokunokwenzeka?

Ukuze ushintshe ifomethi, ungasebenzisa ejwayelekile uhlelo Paint. Ngokwesibonelo, siyowuqonda indlela ukuguqula JPEG yimuphi umfanekiso. Ukuze wenze lokhu, vele uvule isithombe abayifisayo besebenzisa lezo uhlelo Paint, noma ngokuchofoza isithombe oyifunayo, chofoza ngakwesokudla, ukhethe "Shintsha." Ngemva kokuvula isithombe, khetha imenyu "Ifayela" (e izinguqulo ezintsha kuwindo lolu hlelo sika), khetha u- "Londoloza njengohlu" bese ukhetha ibhokisi ngefomethi okudingayo, kuleli cala - JPEG noma i-JPG.

Ngenxa yalezi zinjongo okwaziyo futhi eyaziwa kahle kubo bonke CorrelDRAW, Photoshop, futhi fotokonvertery ekhethekile: PicJet Converter, FastStone PhotoResizer nabanye abaningi. Ezinye zazo ezikuvumela ukuba ukwenze batch ukucutshungulwa izithombe, okuyinto iyehlisa isikhathi ukusebenza nabo.

yi

Sonke kwaqondwa ngokuthi format ingcaca ezinjalo, waveza umehluko oyinhloko phakathi ezinkulu amafomethi image ethandwa, umgamu wawo, wanikeza incazelo emfushane ngamunye wabo. Futhi wathola ukuthi ifomethi JPEG iyathandwa kakhulu okwamanje.

Siphindze safundza kanjani ngokushesha ushintshe usayizi wesithombe ukusebenzisa isofthiwe ye-standard ifakiwe kukhompyutha yakho noma ikhompyutha ephathekayo. Futhi sathi ukuxoxaxoxa mayelana lokuthi kukhona converters ekhethekile, lapho ufuna ngokushesha futhi kalula ushintshe ngefomethi yesithombe.
