Indlela yokujika JPEG

1 Layisha phezulu i JPEG images yakho uze ulinde ukujonga phambi koshicilelo ukuba kuvele.

2 Rhuqa ngaphandle ummandla ofuna ukuwugcina, okanye utshixe ukhetho kwi 1:1, 4:3 okanye 16:9 kwaye urhoxise ngokukhululekileyo ngaphakathi kolu hlobo loqhagamshelwano.

3 Qinisekisa ukutywina - i-rectangle efanayo isetyenziswe kwifayile nganye olayishe kuyo, oko kukuthi indlela emiselweyo ephelela ngokuhambelana ngokuqinisekileyo.

4 Layisha ezantsi ifayili ecutiweyo JPEG, ngazo zonke izinto ezingaphandle kwesakhelo ezilahlekileyo.

Ukusika JPEG Imibuzo ebuzwa rhoqo

Ingaba ifomati yam yombhalo itshintsha indlela eziphatha ngayo i-crop?

It can. I-JPEG yi-codec efanayo ne-JPG phantsi koluhlu olude — i-DCT efana ne-pipeline, i-quantization table efana ne-quantization table, akukho nto malunga nee-pixels ezitshintsha ngegama lefayili. That decides whether the crop is a pure pixel operation or whether the file has to be rebuilt around it.

Nantoni na ekhethekileyo kwi JPEG ekufuneka ikwazi phambi kokuba ndityhale?

Ewe — i.jpeg ne.jpg izilungiso ziyi-bitstream efanayo, ngoko akukho nto apha esebenza ngokuhlukileyo kune-.jpg — kuphela igama lefayili litshintsha. Loluhlobo lweenkcukacha ezibonisa kuphela emva kokuba ubhale ngaphezulu okubhaliweyo okubhaliweyo.

Yintoni impazamo eqhelekileyo xa uqhagamshela JPEG images?

Ukutywina phambi kokwenza ubungakanani kwakhona. Utywina kuqala ukusuka kwi-resolution epheleleyo ebonakalayo, emva koko uguqule ubungakanani besabelo - ukwenza oku kujikeleza kuthetha ukuba ummandla ogcinayo sele ulahlekile inkcukacha ayifuni ukulahleka.

I-Ukusika JPEG ikhetha kwaye icima indawo njani?

Ngokucacileyo, i-crop isetyenziswe kumfanekiso oguqulwe kwikhowudi kwaye i-result iphinde ikhowudiwe, ngoko ibiza udidi olunye; apho i-crop iqala khona ukuwela kuma-8-pixel MCU ama-boundaries i-encoder ingagcina i-original blocks kwaye ixabiso liphela. Urhoxisa ummandla ofuna ukuwubona ngokuthe ngqo kwimboniselo yangaphambili, okanye ubhale ngokuchanekileyo i-pixel ehambelanayo ukuba sele uyazi.

Ndingaqhuba i Ukusika 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.

Ithini into ebangela ukuba i-EXIF ne-data yeprofayili yombala isebenze?

Ikhamera EXIF (ISO, i-shutter, i-lens, i-GPS) kunye ne-ICC efakwe kwiprofayili idluliselwa ngokumiselweyo, kuba ukulahla iprofayili kwenza umbala utshintshe xa uphinda urhweba ngaphakathi. Sebenzisa ukhetho lokhuseleko lokucoca i-metadata phambi kokukhuphela ukuba ujongene nokupapasha ifayili.

Ingaba kukho umda wobungakanani befayili kwi Ukusika JPEG?

Ewe: i-akhawunti ekhululekileyo iqhubekeka imifanekiso ukuya kwi-5 MB nganye, equka ngokucacileyo yonke ikhamera ye-JPG kunye nomfanekiso wefowuni; 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 Ukusika 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.

Kutheni i Word inxuwa liququzelela Ukusika JPEG?

WORD.to ibekwe ngaphaya kweso siphelo esihleliweyo sobomi boxwebhu - i DOCX eyaqhubeka nokubhala, eyaqhubeka nohlobo kunye neyaqhubeka nokungabaza, phambi kokuba umntu ayile iphepha lokuthunyelwa. Iifayili ze-office ziibhokisi ezigcweleyo zosasazo lwabanye abantu - imifanekiso, umsindo ofakwe ngaphakathi, ifonti - ngoko umsebenzi abantu abafuna kuwo uhlala usebenza kumsebenzi abafunayo kuwo onke amaxwebhu. Ukusika JPEG inikezela ukulayisha, icaps ne-akhawunti ngokuguqulwa ngenxa yoko.

Ndiza kwenza ntoni ngeziphumo xa i Ukusika JPEG igqityiwe?

Umguquli kule ndawo uthatha amaxwebhu ngaphandle kwi PDF yokuthumela, kumfanekiso wokufaka nokubhala okucacileyo nantoni na efuna ukufunda ngokudwelisa, kwaye ibuyela umva kwindlela enye. Ukwenza oko emva koko kugcina i-original eguqulelweyo ejikeleze, eyiyo inxalenye ongayi kufumana kwakhona xa iphelelwe lixesha.

Ingaba Ukusika JPEG apha isixhobo esifanayo esisebenza kumasayithi afana nalowo?

Iinjini zinikezelwa - uxwebhu olufanayo lwesixhobo sendlela, abasebenzi abafanayo, amaqondo afanayo. Oku Word site idibanisa kukubona okuqhubekayo ukuphuma kwifomati ye-Office kunye nokuba yintoni engayenzanga, eyiyo umbuzo ngamnye wale misebenzi ijikeleza ngoku. Iqala kwakhona kwinyani enye malunga nefomati le site ibizwa emva: uxwebhu luyi-zip ye-XML, ngoko utshintsho lombhalo luyabiza kwaye ubunzima buhlala bufana nomfanekiso ofakwe ngaphakathi.

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.
