ICO ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-ICO ibe yi-PNG ngaphandle kokulahlekelwa umgangatho womfanekiso?

Layisha phezulu ifayili yakho ye ICO kwaye umguquli usebenzise ukuphuculwa komgangatho owaziyo ifomati ye PNG. Kwifomati engalahlikiyo PNG (PNG, TIFF, BMP) yonke i-pixel igcinwa; kwifomati elahlayo PNG (JPG, WebP) ungalungisa umgangatho phambi kokukhuphela. I-ICO enye igcina iziboniso ezininzi ze icon efanayo kubungakanani obuhlukileyo - 16x16 ukuya kwi-256x256 - ukuze i-OS ikhethe enye eqaqambileyo. I-PNG isebenzisa uxinzelelo lwe-DEFLATE ngaphezulu kwamagqabantshintshi okuskena acociweyo, ngoko ke i-pixel nganye ihlala ngokuchanekileyo, kunye ne-8-bit epheleleyo ye-alpha channel.

Ingaba kukho into elahlekile ekuguquleni phakathi kwe ICO ne PNG?

Akukho data yepixel, hayi. Zonke iifomati zigcina umfanekiso ngaphandle koxinzelelo olulahlekileyo, ngoko ke umfanekiso ophumayo ufana nowo waya ngaphakathi kwaye uguqulelo luyaphinda uphinde luphinde. Okutshintshayo kubungakanani befayili, kwaye oku kusebenza ukuhamba - ubunzulu bombala, iiprofayili ezifakelweyo, amanqanaba noopopayi bonke baxhaswa ngokungalinganiyo phakathi kwefomati ezingalahlekileyo.

Ingaba uguqulelo ICO ukuya ku PNG lugcina ukubonakala ngaphaya?

Ukubonakala ngaphaya kuqhubeka xa PNG 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 PNG endaweni ye-PNG=JPG. I-PNG yaphuhliswa ngowe-1996 njengento engekhoyo kwipateni ye-GIF, kwaye yayiyifomati yomfanekiso ongekhoyo kwi-web.

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

Iiprofayili zombala we-ICC ezifakiwe zifundwa ukusuka kwi-ICO kwaye zidityaniswe kwakhona kwi-PNG 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 ICO ukuya ku PNG?

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

Ndingaguqula iifayili ezininzi ICO zibe PNG ngaxeshanye?

Ewe — tsala iifayile ezininzi ICO 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-ICO ukuya kwi-PNG 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.

I-PNG ifayile yam izakuba nesisombululo esingakanani?

Okumiselweyo yi-1:1 — i-PNG yakho igcina ubungakanani be-pixels yombhalo ovela ku-ICO. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa i-/resize-image/ emva kokuguqula, okanye uyibeke kwi-/image-resize/ utility.

Ingaba i PNG incinane kangakanani na ukuba ayinazo izinto ezibonakalayo ezibonakalayo?

Kwi-JPG / WebP, umgangatho we-75-85 ufumana i-PNG 60-80% encinci kune-ICO ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-PNG engalahliyo (PNG, TIFF), lindele ukonga okuncinci — ngokuqhelekileyo 5-30% nge-deflate / LZW yokucinezela engcono. I-PNG yinketho efanelekileyo yokuthatha imifanekiso yekhusi, ilogos, umzobo womgca nantoni na enemiphetho eqinileyo okanye ebonisa ngaphaya — akukho cingo, akukho mbala obandayo.

Ingaba iifayile zam ICO zifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu ICO ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asizukufunda, sigcine ixesha elide, okanye sisebenzise i-pixel data. Ifestile yokugcina epheleleyo ibhalwe kwi /privacy/.

Ingaba i-ICO ukuya kwi-PNG iguqula imifanekiso enkulu kakhulu (50MP+)?

Ewe, simahla ukuya kwi-100 MB. I-Premium iphatha izingeniso ezinkulu (300 MB+) kunye nobunzulu obukhethekileyo kwi-pixel nganye (16-bit PNG, 32-bit float TIFF). I-pipeline iqhuba imiqolo ukuze ukusetyenziswa kwememori kulinganiswe ngobalo lomqolo, hayi ubalo lwe-pixels jikelele.

Kutheni i-PNG yam eguqulweyo incinci okanye ikhulu kuneleyo ndiyifumeneyo?

A ICO nge-compression enamandla ekhoyo (i-lossy JPG) ihlala ikhula xa i-encoded kwakhona kwi-lossless PNG (PNG, TIFF). I-lossless ICO ihlala ikhula ngokugqithisileyo xa ihamba kwi-JPG / WebP. Uthelekiso luxhomekeke kwizinto eziqulethe umfanekiso — iifoto zicofa ngokuhlukileyo kunemizobo yelayini. I-ICO ayiyiyo ifomati yomfanekiso oqhelekileyo: ikwisakhelo, incinane, kwaye akukho mhleli wefoto oyiphatha njengefayili yomsebenzi wohlobo lokuqala. I-PNG yifomati yomfanekiso ophantsi: umfanekiso ogciniweyo njenge-PNG uhlala ukhulu ngeeyure ezisixhenxe ukuya kwezilishumi kunemifanekiso efanayo njenge-JPG okanye i-WebP.

ICO

ICO ipakisha ubungakanani bemifanekiso engumqondiso emininzi kwifayile enye ukuze iiWindows kunye namacebo okucoca ulwelo akwazi ukukhetha ugqibo oluchanekileyo lwemifanekiso engumqondiso yefavicon kunye neendlela ezimfutshane.

PNG

Iifayili ze-PNG zihambelana nobunzulu obubonakalayo kwaye zisebenzisa ukucinezela okungalahleki, zenza ukuba zilungele amagrafiki, ilogos, kunye nemifanekiso yekhusi.
