Indlela yokuZicimeza JPEG

1 Nciphisa i JPEG images yakho kwibhokisi ephezulu, okanye ukhethe kwisixhobo sakho - akukho nto yokufakela kwaye akukho akhawunti yokuyenza.

2 Khetha ukuba kunzima kangakanani ukucofa: umgangatho okanye injongo ye bitrate, kwaye ngokuzenzekelayo ubungakanani obuncinane ukuba ubungakanani bubalulekile kuwe ngaphezulu kweenkcukacha.

3 Qala umsebenzi kwaye vumela abasebenzi ukuba baphinde bapakishe ifayile; okuqala wakho akatshintshwanga kwindawo.

4 Uthelekiso lobungakanani obutsha nokuqala, emva koko ulayishe ifayili ecinezelweyo JPEG.

Cima JPEG Imibuzo ebuzwa rhoqo

Ndifumana ntoni, kwaye ndingalawula njani utshintshiselwano?

Ifayile enye ecinezelweyo ngengeniso ngalinye, kumgangatho okanye kwinqanaba le-bitrate okhetha kuyo kunokuba kugqibeke okumiselweyo. Ukuba isiphumo asincinci ngokwaneleyo, utshintsho lomlinganiselo okanye ixesha lokuphila luzakwenza ngaphezulu kokutsala umqhubi womgangatho ezantsi.

I-Cima JPEG iyenza njani ifayili ibe ncinane?

Ngokucacileyo, ikhowudi iphinde iqhube i DCT quantumiser kwimeko yomgangatho okhethayo, ngoko ulondolozo luvela kwimeko yomgangatho ophezulu kunokuba kwimeko ye pixels ezincinci - ubungakanani bomfanekiso abutshintshi, kwaye umgangatho 80 yindawo eqhelekileyo emnandi. Akukho nto malunga nayo ixhomekeke ekufakeni kwakho isoftware: umsebenzi uqhuba iserver-side kwaye ubuyisela ifayile egqityiweyo.

Yintoni endinokuyilayisha kwi Cima JPEG?

Nantoni na ekufumaneni usapho lwe-raster - JPG, JPEG, JFIF ne-WebP - kunye neefomati ezingalunganga (PNG, BMP, TIFF) ukuba ufuna ukuzidibanisa kwiqela elinye. Ifomati ifundwa kwisihloko sefayili, hayi kwisiphelo, ngoko ke umfanekiso ogciniweyo nge-suffix engafanelekanga uhlala udlula.

Ingaba kukho umda wobungakanani befayili kwi Cima JPEG?

Ewe: i-akhawunti ekhululekileyo iqhubekeka imifanekiso ukuya kwi-5 MB nganye, equka ngokucacileyo yonke ikhamera ye-JPG kunye nefowuni yomfanekiso; umsebenzi ukwenziwa yi-libjpeg-turbo ne-libwebp, iilayibrari ezifanayo umhleli we-desktop uqhagamshelana nazo. Iifayili ezinkulu zizinto ezi-1 ezimfutshane ezikhululekileyo eziza kukuthintela, kwaye umda yifayili nganye kunokuba yiqela ngalinye.

Ingaba i Cima JPEG iya kunyusa ubunjani be JPEG images yam?

Umthombo olahlwayo sele uyimpumelelo yendlela enye yokugqitha, kwaye nayiphi na imisebenzi efuna ukubuyisela ikhowudi idibanisa enye. Xa umsebenzi ungakwenziwa ngaphandle kokucofa i-pixel data siyenza endaweni, kwaye apho ayikwazi khona ukhetha umgangatho wezinto eziluncedo ngokwakho kunokuba ufumana okumiselweyo okumiselweyo.

Ndingaqhuba i Cima JPEG kwi JPEG images ezininzi ngaxeshanye?

Ewe. Nciphisa iqela lonke kwindawo yolayisho phezulu kwaye ziphole ngokuthe ngqo ngemimiselo efana nayo - le yisizathu esiphambili sokwenza oku kumkhangeli zincwadi kunokuba yifayile enye ngexesha kumhleli. Iiakhawunti ezikhululekileyo ziqhuba ifayile enye kwiqela; i pass iphakamisa loo nto.

Kutheni i EPUB inxuwa liququzelela Cima JPEG?

EPUB.to ibekwe phantsi kwefomati evulekileyo yencwadi ye-e-XHTML kwi zip, ephinda ijikeleze ngoyilo, kwaye ifundeka kwizixhobo zekhompyutha akukho mntu ucinga malunga nobeko. Incwadi yizip egcweleyo yemarkup, imifanekiso kunye nefonti, ngoko ke phantse yonke imisebenzi abantu bezisa kwiwebhusayithi ye-eBook isebenza kwelinye lawona zinto.

Ndifuna i-akhawunti, kwaye ngaba kukho into egcinwa?

Akukho akhawunti, kwaye akukho nto igcinwayo: ulayisho lususwa kubasebenzi emva kokuba umsebenzi ugqibile, akukho nto ifundwayo kwaye akukho nto iqulathe isiqulathi seefayili. Iiakhawunti ezikhululekileyo zikhona kwimbali kunye nobungakanani beqela, hayi kwi access.
