GIF kuya PNG Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho GIF futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomethi ye PNG. U PNG ongalahleki (PNG, TIFF, BMP) wonke ama-pixel agcinwa; u PNG ongelahleki (JPG, WebP) ungahlela umphumela womgangatho ngaphambi kokufaka ngezansi. I-GIF ayilahleki kodwa iphele kumbala we-256-palette ngefremu ngayinye, usebenzisa ukucindezeleka kwe-LZW nombala owodwa ocacile. I-PNG isebenzisa ukucindezeleka 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 engalahleki.

Ingabe ukuguqulwa GIF kuya ku PNG kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho PNG i-PNG, WebP, TIFF, GIF, noma i-SVG. Ukushintsha ku-JPG kuhlanganiswa isixhumi se-alpha esibhekene nesizinda esimhlophe. 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 esingenalutho esizenzakalelayo se-web.

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

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundwa kusuka ku-GIF futhi axhunywe kabusha ku-PNG lapho ifomethi ixhasa khona (JPG, PNG, TIFF, WebP). Amafomethi ngaphandle kwe-inkxaso yeprofayili abuyela emuva ku-sRGB, ogcina amamibala ahambisanayo phakathi kweziboniso eziningi ezimanje.

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

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

Ingabe ngingenza ukuguqulwa kwe-batch kwe-GIF amafayela amaningi ku-PNG ngasikhathi sinye?

Yebo — cindezela amafayela amaningi GIF endaweni yokulayisha futhi sizowabeka emqoka ngokufanayo. Abasebenzisi abamahhala bathola i-100 MB ngefayela ngalinye; iPremium ayinaso isiphetho sefayela ngalinye futhi isebenza nabasebenza ngokufanayo, ngakho-ke isithombe esingu-200 siqediwe ngaphantsi 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 efanayo umhleli wedesktop asebenzisayo, ngekhwalithi yokuphuma efanayo. Ushintsho luyi-batch management ehambisanayo — ama-desktop apps avula ifayela elinye ngasikhathi sinye; sivuma i-batch.

Yini isixazululo sehele lami PNG?

Iphutha ngu 1:1 — PNG yakho igcina ama-pixels ama-dimensions we-GIF. Uma ufuna ukushintsha ubukhulu njengengxenye yokuguqulwa, sebenzisa /resize-image/ ngemuva kokuguqulwa, noma uyibeke nge /image-resize/ utility.

Ingabe i PNG ingaba ncane ngaphandle kwezinto ezibonakalayo ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuthola i-PNG 60-80% encane kuna-GIF ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless PNG (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono. 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 phambili emisebenzini ehlukanisiwe futhi acishwe 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 per-pixel depths (16-bit PNG, 32-bit float TIFF). Ipayipi lisakaza imibhalo ukuze umsebenzisi wememori alinganise ngokubalwa kwemibhalo, hhayi inani eliphelele le-pixel.

GIF

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

PNG

Amafayela we-PNG ahambisana nokubukeka okucacile futhi asebenzisa ukucindezeleka okungalahleki, okwenza kube ngcono kakhulu kuma-graphic, amalogo, nama-screenshots.
