Indlela yokuguqula GIF kuya PNG

Isinyathelo 1: Layisha eyakho GIF amafayela usebenzisa inkinobho engenhla noma ngokuhudula bese uphonsa.

Isinyathelo 2: Chofoza inkinobho ethi 'Guqula' ukuze uqale ukuguqulwa.

GIF kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyiguqula kanjani i-GIF ibe yi-PNG ngaphandle kokulahlekelwa ubuhle besithombe?

Layisha phezulu ihele lakho GIF futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomu le PNG. Ukungabi nalutho PNG (PNG, TIFF, BMP) wonke ama-pixel agcinwa; ukungabi nalutho PNG (JPG, WebP) ungalungisa umphumela womgangatho ngaphambi kokulayisha. I-GIF ayilahleki kodwa iphoqeleke kumbala we-256-palette ngefremu ngayinye, usebenzisa ukucindezeleka kwe-LZW nokucacile kwe-binary ngombala owodwa. I-PNG isebenzisa ukucindezelwa kwe-DEFLATE phezu kwemigqa yokuskena ehlolwe, ngakho wonke ama-pixel ahlala ngokugcwele, kanye ne-8-bit alfa channel ephelele.

I GIF yami iphila — yini ekwenzeke kwezinye ifreyimu?

Ifreyimu yokuqala kuphela ehlala, ngoba PNG iyifomethi ehlala khona engenandawo yokugcina okushiwo. Uma udwebo lubalulekile, bheka ifomethi edlalayo, noma uguqule ibe yividiyo equkethe isithombe futhi ugcine ukunyakaza. I-PNG iyifomethi yesithombe esibi: isithombe esigcinwe njenge-PNG sivame ukuba likhulu izikhathi eziyisithupha kuya kweziyishumi kunesithombe esifanayo njenge-JPG noma i-WebP.

Ingabe kukhona okulahlekile ekushintsheni phakathi kwe GIF 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 GIF 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. Uma ufuna ukubukeka okucacile esinqumweni, bheka ukubonakala okucacile okuqaphelayo PNG endaweni ye-PNG=JPG. I-PNG yakhiwa ngo-1996 njengento eshintshayo engekho emthethweni ye-GIF, futhi yashintsha ibe yifomethi yesithombe esingasebenzisi iphutha ye-web.

Ingabe iprofayili yami yombala (sRGB / Adobe RGB / CMYK) izohlala GIF kuya PNG?

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundeka kusuka ku-GIF futhi axhunywe kabusha ku-PNG lapho ifomu lixhasa khona (JPG, PNG, TIFF, WebP). Amafomu enza iphrofayli ayixhasi ubuyela emuva ku-sRGB, okugcina amamibala ahambisana nemboniso yamanje.

Yini mayelana ne-EXIF metadata uma uguqula GIF kuya ku PNG?

Ikhamera EXIF (ISO, i-shutter, i-lens, GPS coords) igcinwa ngokuzenzakalela ngesikhathi GIF → PNG lapho amafomethi amabili exhasa i-metadata. Sebenzisa ukhetho lokufihla ukususa i-metadata ngaphambi kokulayisha uma ufuna ukuhlanganisa izithombe ngaphandle kokubeka indawo.

Ingabe ngingakwazi ukushintsha amafayela amaningi GIF abe PNG ngasikhathi sinye?

Yebo — cindezela amafayela ahlukahlukene GIF 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 GIF 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-GIF. 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-GIF 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.

Ingabe amafayela ami GIF afihlakele ngesikhathi sokuguqulwa?

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

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

Yebo, mahhala kuze kube yi-100 MB. I-Premium iphatha izingeniso ezinkulu (300 MB+) kanye ne-exotic pixel-per-depth (16-bit PNG, 32-bit float TIFF). Ipayipi lisakaza imigomo ukuze umlando usebenzise izilinganiso ngenani lemigomo, hhayi inani le-pixel.

GIF

Amafayela e-GIF asekela izithombe ezinyakazayo kanye nemibala elinganiselwe, afaneleka kakhulu izithombe ezilula, ama-meme, kanye nezithonjana.

PNG

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