GIF kuya TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho GIF futhi umguquli wethu ufaka ukulungisa umgangatho okwaziyo ifomethi ye-TIFF. 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-GIF ayilahleki kodwa iphele kumbala we-256-palette ngefremu ngayinye, usebenzisa ukucindezeleka kwe-LZW nombala owodwa ocacile. I-TIFF iyindawo yokuqoqa engaphezu kwe-codec: ingagcina idatha engacindezelwanga, i-LZW, i-ZIP noma i-JPEG, kuze kube yi-32 bits ngasinye, ngekhasi eliningi kwifayela elilodwa.

I GIF yami iphila — yini ekwenzeke kwezinye ifreyimu?

Ifreyimu yokuqala kuphela ehlala, ngoba TIFF iyifomethi ehlala khona engenandawo yokugcina okushiwo. Uma udwebo lubalulekile, bheka ifomethi edlalayo, noma uguqule ibe yividiyo equkethe isithombe futhi ugcine ukunyakaza. Ukulungelelaniswa kwe-TIFF kuyinkinga yayo - ama-TIFF amabili angakhiwa ngendlela ehlukile yokuthi isofthiwe efunda enye iphutha kwezinye - futhi amafayela akhulu.

Ingabe kukhona okulahlekile ekushintsheni phakathi kwe GIF ne TIFF?

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 TIFF kugcina ukubukeka okucacile?

Ukubukeka okucacile kuhlala lapho TIFF 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-TIFF. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwezinto eziphilayo ezijwayelekile.

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

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundwa kusuka kumthombo GIF futhi axhunywe kabusha ku-TIFF 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 GIF usuka ku-TIFF?

Ikhamera EXIF (ISO, ishutter, ilensi, GPS) igcinwa ngokuzenzakalela ngesikhathi GIF -> TIFF 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 GIF amafayela ku TIFF ngasikhathi sinye?

Yebo — cindezela amafayela amaningi GIF 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 GIF kuya ku TIFF 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 TIFF?

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

Ingabe ihele TIFF lincane uma kungabonakali izinto ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuletha i-TIFF 60-80% encane kune-GIF ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless TIFF (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono kune-source esenayo. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC ifaka amaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingekayo ukuphrinta nokugcinwa kwemisebenzi.

Ingabe amafayela ami GIF afihlakele ngesikhathi sokuguqulwa?

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

Ingabe i-GIF kuya ku-TIFF 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.

GIF

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

TIFF

Amafayela e-TIFF asekela ukujula kwe-bit ephezulu kanye nokucindezelwa okungenakulahlekelwa, okulungele ukuthwebula izithombe zobungcweti kanye nokuphrinta.
