I-ICO eyodwa igcina iziboniso eziningi zesithonjana esifanayo eziyizinkulungwane ezahlukene — 16x16 kuya ku-256x256 — ngakho-ke OS ingakhetha enye ecacile. I-PNG isebenzisa ukucindezelwa kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele.

Ingabe kukhona okulahlekile ekushintsheni phakathi kwe ICO ne PNG?

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 engalahlekile.

Ingabe ICO kuya ku PNG ukuguqulwa kugcina ukubukeka okucacile?

Ukubukeka okucacile kuqhubeka uma PNG i-PNG, WebP, TIFF, GIF, noma SVG. Ukushintsha ku-JPG kwenza i-alpha channel ibe mhlophe.

Yebo — cindezela amafayela ahlukahlukene ICO endaweni yokulayisha bese siwafaka emgodini ngokufanayo. Abasebenzisi abamahhala bathola i-100 MB ngefayela ngalinye; iPremium ayinaso isikhala ngasinye sefayela futhi isebenza nabasebenza ngokufanayo, ngakho-ke isithombe esingu-200 siqediwe ngezansi kwemizuzu emibini.

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

Ukuguqulwa kwefomethi eqondile sisebenzisa i-libpng / libjpeg-turbo / libwebp / ImageMagick pipes efana ne-desktop editor, ngekhwalithi yokuphuma efana. Ushintsho luyi-batch parallel handling — desktop applications open one file at a time; we accept a batch.

Yini isixazululo esizobe sikhona kuhele PNG?

Okuzenzakalelayo yi-1:1 — PNG yakho igcina ama-pixels alinganayo we-ICO. Uma ufuna ukuguqula ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva kokuguqulwa, noma uyibeke nge /image-resize/ utility.

Ingabe i PNG ingancane uma ingabonakali i-artifacts?

I-JPG / WebP, umgangatho 75-85 uvame ukuthola i-PNG 60-80% encane kune-ICO ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. I-lossless PNG (PNG, TIFF), cabanga ukulondoloza okuncane - ngokuvamile 5-30% nge-deflate / LZW yokucindezela. I-PNG iyisinqumo esifanele sezithombe-skrini, amalogo, umdwebi we-line kanye nanoma yini eneziphetho eziqinile noma ezicacile — akukho ukusakaza, akukho umbala obandayo.

PNG

Amafayela e-PNG asekela ukucaca futhi asebenzisa ukucindezela okungenakulahlekelwa, okwenza afaneleke kakhulu kuma-graphics, ama-logo, kanye nezithombe-skrini.
