Indlela yokufaka i-watermark JPEG

1 Layisha phezulu i JPEG images ofuna ukuyiphawula, sele kubungakanani babo bexesha elizayo - uphawulo lwamanzi luya emva kokuguqula ubungakanani, hayi phambi kwayo.

2 Layisha phezulu ilogo ye-PNG ebonisa ngaphaya okanye ubhale umbhalo wakho, emva koko ukhethe ifonti, umbala nokungaboni ngaphaya.

3 Misela indawo, okanye utshintshe ukuphinda-phinda okuthe tyaba xa umqondiso wekona enye ulula kakhulu ukutywina.

4 Layisha ezantsi ifayili ephawulwe ngamanzi JPEG; akukho nto ingaphezulu ifakwe kuyo.

Uphawu lwamanzi JPEG Imibuzo ebuzwa rhoqo

Ndimele ndibeke uphawu lwamanzi phambi okanye emva kokuguqula ubungakanani?

Emva. Yenza uphawu lwamanzi olugqibeleleyo olunikezelwayo kubungakanani bayo olungagqibekanga, ukuze uphawu luhlale lufundeka kwaye lulinganiswe. Ukwenza uphawu lwamanzi lomphathi oza kuqhubekekisa kwakhona kuthetha ukuba uphawu luya kuphinda lusampuliwe kwaye lucinezelwe kunye nezinye zonke izinto.

Ndingasebenzisa ilogo yam, okanye umbhalo kuphela?

Ukongeza, ulayishe ilogo ye-PNG ecacileyo, okanye ubhale umbhalo uze ukhethe ifonti, umbala nokungabonakali ngaphaya. Ukuphinda-phinda okuthe tyaba kufumaneka xa umqondiso wekona enye ulula kakhulu ukutywina.

Ingaba ifomati yefayile inegalelo ekubeni umqondiso wamanzi uphuma njani?

Iyenza. 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. Eli lilawula ukuba uphawu oluthe tyaba luya kudityaniswa njani kwizinto ezingaphakathi.

Nantoni na ekhethekileyo kwi JPEG ekufuneka uyazi?

Ewe — i.jpeg ne.jpg izilungiso ziyi-bitstream efanayo, ngoko akukho nto apha esebenza ngokuhlukileyo kune-.jpg — kuphela igama lefayili litshintsha. Isebenza xa kumsebenzi wakho uqhubekeko-msebenzi iphawu kufuneka lisetyenziswe.

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?

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 Uphawu lwamanzi JPEG ibiza nantoni na?

Uphawu lwamanzi JPEG 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.

Kutheni i WebM inxuwa liququzelela Uphawu lwamanzi JPEG?

WEBM.to ibekwe phantsi kwebhokisi ye-web evulekileyo ekhethiweyo — VP9 okanye AV1 nge-Opus audio, ikhowudiwe ngokusemthethweni ngazo zonke iziphequluli zexesha elidlulileyo kwaye ayifuni iplugin, ilayisensi okanye umdlali. Ividiyo yimeko apho izithuthi ezijikelezayo ezingaphezulu zibuhlungu kakhulu - iifayile zikhulu kwaye zonke ukukhuphela zibiza iiyure ezilungileyo. Ukusebenza Uphawu lwamanzi JPEG kwindlela yokuhambisa i-pipeline efanayo njengeeguqulelo kuthetha ukuba ukukhuphela omnye ugubungela umsebenzi wonke endaweni yokukhuphela omnye kwisixhobo ngasinye.

Ndiza kwenza ntoni ngeziphumo xa i Uphawu lwamanzi JPEG igqityiwe?

Umguquli kule ndawo uhambisa ividiyo phakathi kweWebM, MP4, MKV, MOV kunye nezinye, okanye utsala umculo ophumayo ngokupheleleyo, ngaphandle kokukhuphela enye. Ukulandelela okunjalo kubaluleke kakhulu kwividiyo kunezinye iindawo: ukuphinda- ukhowudi nganye kuhlobo olunye, ngoko ke, xa kuncinci kwabo phakathi kombhalo kunye nefayile opapashayo, ibonakale ingcono.

Ingaba Uphawu lwamanzi JPEG apha isixhobo esifanayo esisebenza kumasayithi afana nalowo?

Iinjini zinikezelwa - i-ffmpeg enye yokwakha nge x264, x265 ne libvpx, abasebenzi abafanayo, amaqondo afanayo. Oku WebM inxuwa lidibanisa kukubona kwiinqanawa ne codecs: ezi zidibanisa zidlala naphi na, ezifuna ukuphinda zikhowudi kwaye ezi zingakopela ngokulula. Oku kuqala kwinyani enye malunga nefomati le nxuwa libizwa emva: I-WebM yi-VP9 okanye i-AV1 ene-Opus yesandi, esiza kuyenza ikhowudi ikwi-browser kodwa esiya kuyenza ikhowudi kwi-desktop editors xa irhweba ngaphakathi.
