JPG ukuba SVG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-JPG ibe yi-SVG ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayili yakho ye JPG kwaye umguquli usebenzise ukuphuculwa komgangatho owaziyo ifomati ye SVG. Kwifomati engalahlikiyo SVG (PNG, TIFF, BMP) yonke i-pixel igcinwa; kwifomati elahlayo SVG (JPG, WebP) ungalungisa umgangatho phambi kokukhuphela. I-JPG ilahlekile: umfanekiso uguqulwa nge-DCT, i-quantized, kunye ne-entropiya-ekhowudiweyo, ngeqhosha lomgangatho elilawula ukuba kuphi okuninzi okulahlekileyo. I-SVG igcina iimpawu njengendlela ye-matematics nombhalo njengombhalo, hayi njenge-pixels, ngoko ke luxwebhu kunokuba luyi-raster grid.

Ingaba i JPG imifanekiso iya kuguqulwa ibe yi SVG ecocekileyo?

Kuphela ukuya kwincopho, kwaye kufanelekile ukumisela okulindelekileyo kuqala. Ukubopha kujika imimandla ye-pixel ibe ziindlela, ezisebenza kakuhle kwilogos, umzobo womgca kunye nomfanekiso ongwevu-ombala ocacileyo onemida. Umfanekiso awunamida, ngoko ubopha luvelisa okanye uthelekiso olunobungozi okanye SVG ngeezigidi zeendlela ezikhulu kwaye ezicothayo ukuzoba kunezo zakuqala. I-SVG ayikwazi ukubonakalisa umfanekiso - ukulandelela omnye kwenza ukuba kubekho ukuthelekiswa okunobunzima okanye ifayili enkulu kune-raster ephambili.

Ndingafumana ukubonakala okucacileyo xa umfanekiso u SVG?

Ifomati SVG ixhasa oku, kodwa uguqulelo alukwazi ukulivelisa. A JPG ayinasiqhagamshelanisi se-alpha, ngoko ke yonke i-pixel equka indawo yangasemva ifika icacile ngokupheleleyo. Phumeza /susa indawo yangasemva/ emva koko ukucima isiqalo — ngoko i-alpha isiqhagamshelanisi SVG ibonelela ngento yokugcinwa. I-SVG ibonisa kakuhle nakweyiphi na ubungakanani, ihlala ihlela, ikhangela kwaye iguqula njengombhalo ocacileyo, kwaye ihlala ilingana ne-PNG.

Ingaba ukutshintsha JPG ukuya ku SVG kubuyisela ubunjani obulahlekileyo?

Hayi. Ii-artefacts zokucinezela eziphekwe kwi JPG zii-pixels zedata eziqhelekileyo ngoku, kwaye SVG igcina kakuhle kunokuba isuse. Ifayile ihlala ikhula, ngamanye amaxesha ikhula amaxesha amaninzi. Kubalulekile ukwenza phambi kohlela, kuba utshintsho oluthe kratya aluyi kunyusa udidi lwesibini lolahleko phezulu. I-JPG ayinakubonakaliswa ngokucacileyo, ikhupha ngaphezulu xa igcinwa kwakhona, kwaye ivelisa ukutshixa okubonakalayo kumbala othambileyo nombhalo oqaqambileyo.

Ingaba umbala wam we-CMYK uya kuqhubeka nokuguqulwa kwi SVG?

Iguqulwe kwi sRGB, kuba SVG ayinayo i CMYK indlela. Ukusetyenziswa kwesikrini oku kulungile. Ushicilelo lweshishini akusebenzi - utshintsho lwegama lokutshintsha indlela imibala ethambileyo ephindayo kwiqhosha, ngoko thumela umshicileli okuqala JPG endaweni ye SVG.

Ingaba i SVG igcina i-EXIF data evela kum JPG?

Ngokungagqibekanga ewe, apho naphi na apho injongo ifuna ukubekwa khona - imodeli yekhamera, izicwangciso zokubonisa, iinwele kunye neGPS ikhowudi zihamba zonke. I-GPS yindawo efanele ucinga ngayo: ukuba umfanekiso uzakupapashwa, sebenzisa ukhetho lwe-strip-metadata ukuze ungasazibonisi apho umfanekiso uthathwe khona. I-JPG yi-JPEG eqhelekileyo ukusukela ngo-1992, kwaye emva kweminyaka emithathu ihlala i-format esetyenziswa ziikhamera ezininzi kunye ne-web sites ezininzi zomfanekiso.

Ukuziphatha kombhalo ngaphakathi kwe-SVG kunjani?

Kwi-SVG, umbhalo ngumbhalo obonakalayo - okhethwayo, okhangelayo nophinda-uhlobo, kwaye ufuna ifonti ukuba ikhona okanye ifakwe ukuze ibonise njengoko kumiselwe. Ukutshintsha ukusuka kwi-SVG kuguqula umbhalo ube yi-pixels okanye ube ngumbhalo woxwebhu ngokuxhomekeke kwinjongo; ukuguqula ukuya kwi-SVG kuguqula kuphela umbhalo obonakalayo ukuba umbhali wayene-mantle wombhalo wokuqalisa.

Ingaba uguqulelo JPG ukuya ku SVG lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa SVG yi-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha ukuba yi-JPG kwenza ukuba isiqhagamshelanisi se-alpha sifane nesiqalo esimhlophe. Ukuba ufuna ukubonakala ngaphaya kwiziphumo, cwangcisa ukubonakala ngaphaya okuziyo SVG endaweni ye-SVG=JPG. I-SVG yifomati ye-W3C ye-XML-based vector, icebiso ukusukela ngo-2001 kwaye ngoku ivela kumkhangeli zincwadi wonke.

Ingaba i-inkangeleko yam yombala (sRGB / Adobe RGB / CMYK) iya kuhlala i JPG ukuya ku SVG?

Iiprofayili zombala we-ICC ezifakiwe zifundwa ukusuka kwi-JPG kwaye zidityaniswe kwakhona kwi-SVG apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ngaphandle koxhaso lweprofayili zibuyela kwi-sRGB, egcina imibala ihambelana nakwimboniselo ezininzi zexesha elidlulileyo.

Yintoni malunga ne-EXIF metadata xa uguqula JPG ukuya ku SVG?

I-EXIF yekhamera (ISO, i-shutter, i-lens, i-GPS coords) igcinwa ngokumiselweyo ngexesha JPG → SVG xa zombini iifayili zixhasa i-metadata. Sebenzisa ukhetho lobumfihlo ukususa i-metadata phambi kokukhuphela ukuba ufuna ukuthumela imifanekiso ngaphandle kwendawo yomhlaba.

Ndingaguqula iifayili ezininzi JPG zibe SVG ngaxeshanye?

Ewe — tsala iifayile ezininzi JPG kwindawo yokulayisha kwaye sizibeke kwifolokhwe ngokuthe tye. Abasebenzisi abakhululekileyo bafumana i-100 MB ngefayili nganye; i-Premium ayinasiphelo sefayili nganye kwaye iqhuba abasebenzi abathe tye abaninzi, ngoko ke iqela lemifanekiso engama-200 ligqiba ngaphantsi kwemizuzu emibini.

I-JPG ukuya kwi-SVG ithelekiswa njani ne-Photoshop / i-GIMP kumsebenzi ofanayo?

Uguqulelo lwefomati ethe ngqo siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imibhobho efanayo umhleli we desktop ayisebenzisayo, ngemveliso elinganayo. Utshintsho luyinkqubo ethe tye ethe tye - iinkqubo ze desktop zivula ifayile enye ngexesha; siyayamkela iqela.

JPG

Iifayili ze-JPG zisebenzisa ukucinezela okulahlekileyo okulungelelanisiweyo kwiimifanekiso, kunike ubungakanani befayili encinci ngelixa kugcinwa isisombululo esibonakalayo.
