PNG kuya ICO Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-PNG ibe yi-ICO ngaphandle kokulahlekelwa ubuhle besithombe?

Layisha phezulu ihele lakho PNG futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomethi ye-ICO. Kuzo zonke izimo ezingenalutho (PNG, TIFF, BMP) wonke ama-pixel agcinwa nge-bit-by-bit; kuzo zonke izimo ezingenalutho (JPG, WebP) ungalungisa i-quality factor (iphutha 90) ngaphambi kokufaka ngezansi. I-PNG isebenzisa ukucindezeleka kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele. I-ICO eyodwa igcina iziboniso eziningi zesithonjana esifanayo eziyizinkulungwane ezahlukene — 16x16 kuya ku-256x256 — ngakho-ke OS ingakhetha enye ecacile.

Ingabe i ICO iqukethe izilinganiso?

Kuhlanganise 16x16, 32x32, 48x48 ne 256x256 futhi udlulise yonke imibandela yeWindows neziphequluli ezicela. ICO eyodwa igcina zonke, ngakho-ke uhlelo lokusebenzela lukhetha okufanayo okuncane endaweni yokusatshalaliswa kwesayizi eyodwa ngezansi nokwenza kube nzima. Qala kusuka ku square PNG — noma yini eminye ithola ibhokisi leposi noma itholwe.

Ingabe kukhona okulahlekile ekushintsheni phakathi kwe PNG ne ICO?

Akukho data ye-pixel, cha. Ifomethi zombili zigcina isithombe ngaphandle kokucindezeleka okulahlekile, ngakho isithombe esiphumayo sifana nesinye esingene ngaphakathi futhi ukuguqulwa kungaphinda kwenziwe ngaphandle kweso. Okunye okushintshayo yisayizi yefayela, futhi okunye okuphawulekayo ukushayela — ububanzi bombala, amaprofayili afakwe, ama-layers kanye nobuciko bonke baxhaswa ngokuhlukile phakathi kwefomethi engalahleki.

Ingabe ukuguqulwa PNG kuya ku ICO kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho ICO i-PNG, WebP, TIFF, GIF, noma i-SVG. Ukushintsha ibe yi-JPG kuzoba ne-alpha channel efana nendawo yangasemva ebomvu — uma ufuna ukubukeka okucacile, khetha okuzokwazi ukubukeka okucacile endaweni ye-ICO. I-ICO iyifomethi yesithombe-skrini seWindows, futhi iyifomethi yesithombe kuphela esivunyelwe yiziphequluli ku /favicon.ico.

Ingabe iprofayili yami yombala (sRGB / Adobe RGB / CMYK) izohlala i PNG kuya ku ICO?

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundwa kusuka kumthombo PNG futhi axhunywe kabusha ku-ICO lapho ifomethi ixhasa khona (JPG, PNG, TIFF, WebP). Amafomethi enza i-profayili ayixhasi ibuyela emuva ku-sRGB nge-soft-proof step.

Yini ekwenzeke ku-EXIF metadata uma uguqula PNG usuka ku-ICO?

Ikhamera EXIF (ISO, ishutter, ilensi, GPS) igcinwa ngokuzenzakalela ngesikhathi PNG -> ICO lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukushintsha ubumfihlo ukususa i-metadata ngaphambi kokulayisha ngezansi uma ufuna ukuhlanganisa izithombe ngaphandle kokutholakala kwendawo noma idivayisi-fingerprint.

Ingabe ngingenza ukuguqulwa kwekhulu le PNG amafayela ku ICO ngasikhathi sinye?

Yebo — cindezela amafayela amaningi PNG endaweni yokulayisha futhi babeke ifile ngokufanayo. Isigaba esimahhala sithatha ama-100 MB ngefayela ngalinye; iPremium ayinaso isiphetho sefayela ngalinye futhi isebenza ngemisebenzi eminingi efana, ngakho-ke isithombe esingu-200 siqedela ngezansi kwemizuzu emibini.

Ingabe PNG kuya ku ICO iqhathaniswa kanjani ne-Photoshop / GIMP ngemisebenzi efanayo?

Ukuguqulwa kwefomethi elula sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efana ne-desktop editor esebenzisa, ngekhwalithi efanayo. Ushintsho ukuthi amathuluzi wedesktop avula ifayela elinye ngasikhathi sinye; sivumela iqembu futhi sisebenzisana nabo kubasebenzi bekhasimende.

Yini isixazululo kanye nezici zehele ICO?

Ukuziphatha okuzenzakalelayo yi-1:1 — i-ICO yakho yesokudla inezici ze-pixel ezifanayo ne-PNG. Uma ufuna ukushintsha ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva, noma ubeke izinhlelo nge- /image-pipeline/ utility.

Ingabe ihele ICO lincane uma kungabonakali izinto ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuletha i-ICO 60-80% encane kune-PNG ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless ICO (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono kune-source esenayo. I-ICO ivumela ifayela elinye lisebenzele ibha yokusebenzela, uhlu lwefayela, isinqumli sedesktop kanye nethebhu yokubuka ikhasi ngaphandle kokubheka ukuthi yiziphi zazo eziphinde zathathwa.

Ingabe amafayela ami PNG afihlakele ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu PNG aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukufunda, ukugcina, noma ukuhlanganisa idatha ye-pixel. Ifasitela eligcwele lokugcinwa libhalwe ku /privacy/.

Ingabe i-PNG kuya ku-ICO isebenza ngezithombe ezinkulu kakhulu (50MP+)?

Yebo, mahhala kuze kube yi-100 MB. I-Premium iphatha izingeniso ezinkulu kakhulu (300 MB+) kanye ne-exotic per-pixel depths (16-bit PNG, 32-bit float TIFF, HEIF 10-bit). Ipayipi lisakaza imikhawulo ye-pixel ngakho-ke inkumbulo isebenzisa izilinganiso ngenani lemikhawulo, hhayi inani le-pixel jikelele.

PNG

Amafayela we-PNG asebenza ngokucacile futhi asebenzisa ukucindezeleka okungalahleki, okwenza kube ngcono kakhulu kuma-graphic, amalogo, nama-screenshots.
