ICO ukuba PNG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayile yakho ICO kwaye umguquli usebenzise umgangatho owaziyo wefomati efanelekileyo ye PNG. Ukungabikho kolahleko PNG (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko PNG (JPG, WebP) ungalungisa umgangatho womsebenzi 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 PNG lugcina ukubonakala?

Ukubonakala ngaphaya kuqhubeka xa PNG i-PNG, WebP, TIFF, GIF, okanye SVG. Ukutshintsha kwi-JPG kugubungela isiqhagamshelanisi se-alpha phantsi kokungasemva omhlophe. 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 iprofayili yam yombala (sRGB / Adobe RGB / CMYK) izakuhlala i ICO ukuya ku PNG?

Iiprofayili zombala we-ICC ezifakwe ngaphakathi zifundwa ukusuka kwi ICO kwaye zidityaniswe kwakhona kwi-PNG apho ifomati ixhasa khona (JPG, PNG, TIFF, WebP). Iifomati ezingaxhaswanga zibuyela kwi-sRGB, egcina imibala ihambelana nakwimboniselo eninzi yexesha elidlulileyo.

Yintoni malunga ne-EXIF metadata xa uguqula ICO ukuya 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 kolwazi lwendawo.

Ndingaguqula iifayili ezininzi ICO zibe PNG ngaxeshanye?

Ewe - tsala iifayile ezininzi ICO kummandla wokulayisha kwaye sizibeke kwifolokhwe ngokuthe ngqo. Abasebenzisi abakhululekileyo bafumana i-100 MB kwifayili nganye; iPremium ayinalo icebo kwifayili nganye kwaye iqhuba abasebenzi abathe ngqo, ngoko ke umfanekiso we-200-iqela ligqiba ngaphantsi kwemizuzu emibini.

I-ICO ithelekiswa njani ne-PNG kwi-Photoshop / i-GIMP kumsebenzi ofanayo?

Uguqulelo lwefomati ethe ngqo siqhuba i libpng / libjpeg- turbo / libwebp / ImageMagick imijelo yomhleli we desktop osebenzisa, ngemveliso efanayo yobunjani. Utshintsho luhamba ngaphaya kolawulo lweqela - iinkqubo ze desktop zivula ifayile enye ngexesha; siyamkela iqela.

Uphi ubungakanani obuzakubakho kwifayili yam PNG?

Okumiselweyo ku 1:1 — PNG wakho ugcina ubungakanani be-pixels yomthombo ICO. Ukuba ufuna ukuguqula ubungakanani njengenxalenye yokuguqula, sebenzisa /resize-image/ emva kokuguqula, okanye uyibeke kwi- /image-resize/ utility.

Ingaba i PNG incinane kangakanani na ukuba ingabonakali i-artifacts?

Kwi-JPG / WebP, umgangatho we-75-85 ufumana PNG 60-80% omncinane kune-ICO ngaphandle kotshintsho olubonakalayo kumgama wokujonga oqhelekileyo. Kwi-lossless PNG (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono. 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 — iifayili ezilayishwe phezulu ICO ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe ngaphakathi kwemizuzu. Asiyi kufunda, sigcine ixesha elide, okanye sinikezele i-pixel data. Ifestile yokugcina epheleleyo ibhalwe kwi /privacy/.

Ingaba i-ICO ukuya kwi-PNG iguqulela isebenza kwimifanekiso emikhulu kakhulu (50MP+)?

Ewe, simahla ukuya kwi-100 MB. I-Premium iphatha izingeniso ezinkulu (300 MB+) kunye nobunzulu obungenakulinganiswa kwi-pixel nganye (16-bit PNG, 32-bit float TIFF). I-pipeline ijikelezisa imiqolo ukuze ukusetyenziswa kovimba weefayili kulinganiswe ngobalo lomqolo, hayi ubalo lwee-pixels ezipheleleyo.

ICO

ICO ipakisha ubungakanani bemifanekiso engumqondiso emininzi kwifayile enye ukuze iiWindows kunye namacebo okucoca ulwelo akwazi ukukhetha isisombululo esifanelekileyo semifanekiso engumqondiso yefavicon kunye neendlela ezimfutshane.
