Indlela yokufaka izihluzi ku JPEG

1 Layisha phezulu i JPEG images ofuna ukuyiphatha.

2 Khetha iziphumo zakho - i-greyscale, sepia, i-invert, i-blur, i-sharpen, i-brightness, i-contrast ne-saturation - kwaye umisele amandla nganye.

3 Sebenzisa zonke ezi zinto kwindlela enye edlulayo kunokuba uqhube isixhobo ngokuphindaphindayo, oku kukwenza ukulimala okubonakalayo.

4 Layisha ezantsi ifayili ecociweyo JPEG, kwaye ugcine eyakho eyamva nje: le yindawo ekuphela kwayo yokubuyisela oyenzayo.

JPEG Iicebo lokucoca ulwelo Imibuzo ebuzwa rhoqo

Ziziphi iziphumo ezifumanekayo?

Isikali esingwevu, i-sepia, ukujika, ukuqaqamba, ukuqaqamba, ukukhanya, u kontrast kunye nokulungiswa kokulungiswa. Ziyakwazi ukudityaniswa, kwaye ukudityaniswa kwabo kwindlela enye kungcono kunenkqubo yesixhobo ephindaphindwayo.

Ingaba ifomati yombhalo itshintsha indlela icebo lokucoca ulwelo elibonakala ngayo?

Iyakwazi. 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. Ubunzulu bombala kunye nemodeli yengqokelela yezixhobo ngokukodwa igqiba ukuba i-gradient okanye ukucaca kungabonakaliswa njani ngokulula.

Ndinokuyibuyisela icebo lokucoca emva kokukhuphela?

Hayi - isiphumo sibhakiwe kwimveliso ye pixels, eyiyo incopho yokusebenzisa. Gcina ifayile yokuqala; leyo yiyo uyenza kwakhona. Isikali esingwevu nokungaboni ngaphaya ngokukodwa ushiye ulwazi olungenakubuyiselwa.

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

Oku kuxhomekeke kwisixhobo. Ukucofa kunqakraza i-EXIF kunye neprofayili yombala ofakwe ngaphakathi ukulondoloza isithuba, ngelixa uhlela njengenguqulo yobungakanani okanye ujikeleziso ungagcina. Akukho mmiselo kule phepha oza kukhetha, ngoko khangela ifayile ngombonisi we-metadata phambi kokukhutshwa ukuba indawo ye-data ibalulekile.

Ingaba i JPEG Iicebo lokucoca ulwelo ibiza nantoni na?

JPEG Iicebo lokucoca ulwelo ikhululekile ngaphandle kwe akhawunti kwaye idibanisa akukho phawu lwamanzi. Ulayisho phezulu neziphumo zicinywa ngokuzenzekelayo malunga neyure ezi 24 emva komsebenzi, oshiya ixesha lokulayisha ezantsi iziphumo.

Yintoni endinokuyilayisha kwi JPEG Iicebo lokucoca ulwelo?

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.

Kutheni i PDF inxuwa liququzelela JPEG Iicebo lokucoca ulwelo?

PDF.to ikhona kuba iPDF yindawo apho amaxwebhu ahamba khona ukuba anikezelwe khona kwaye indawo ebuhlungu yokugcina xa sele besebenza kuyo, ngoko ke uninzi lomsebenzi apha luthetha ngento esuka okanye esuka kulo lizwe ngokuzithemba. Uxwebhu luyafika rhoqo kwimeko ekufuneka lishiye kuyo: lukhulu kakhulu, luya kulandela ngendlela engafanelekanga, lutshixiwe, okanye uvavanyo olungambhalo kulo. JPEG Iicebo lokucoca ulwelo luhlala kwi upload efanayo ne akhawunti efanayo njengeeguqulelo kuba loo misebenzi ivela ndawonye.

Ndiza kwenza ntoni ngeziphumo xa i JPEG Iicebo lokucoca ulwelo igqityiwe?

Umguquli kule ndawo uhambisa amaxwebhu phakathi kwe PDF, Igama, imifanekiso, umbhalo ocacileyo kunye neeBook iifomati kumnye umgca, ngoko nantoni na ephuma kwisixhobo apha inendawo yokuya phambili ngaphandle kokukhuphela kwesibini. Ukusebenza emva JPEG Iicebo lokucoca ulwelo kunokuba phambi igcina ubeko lwephepha olukhuselekileyo ngenyathelo elinokuthi liyifane.

Ingaba JPEG Iicebo lokucoca ulwelo apha isixhobo esifanayo esisebenza kumasayithi afana nalowo?

Iinjini zinikezelwa - uxwebhu olufanayo lwesixhobo sendlela, abasebenzi abafanayo, amaqondo afanayo. Oku PDF site idibanisa kukubona xa ifayile kufuneka ihlale uxwebhu kwaye xa ifuna ukuba yinto enye, eyona nto igqiba izixhobo ezininzi ngokulula ukwenza kuwe. Iqala kwakhona kwi nto enye malunga nefomati le site ibizwa emva: i-PDF yi-object graph, hayi umfanekiso wephepha, ngoko umbhalo uhlala ukhethwa kwaye i-vectors ihlala iqaqambileyo nokuba kwenzeka ntoni kwi-raster equlethe ngaphakathi.

Ndifuna i-akhawunti, kwaye ngaba kukho into egcinwa?

Akukho akhawunti ifunekayo. Ulayisho phezulu kunye neziphumo zigcinwa malunga neyure ezili-24, eshiya ixesha lokulayisha ezantsi iziphumo, kwaye ke zicinywe ngokuzenzekelayo; akukho mntu ufunda, uluhlu okanye ubonisa izikhombisi. Iifayile ezininzi kwimisebenzi enye zifuna inkqubo ehlawulweyo.
