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 ufaka ukulungisa umgangatho okwaziyo ifomethi ye TIFF. U TIFF ongalahleki (PNG, TIFF, BMP) wonke ama-pixel agcinwa; u TIFF 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-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 ku-JPG kuhlanganiswa isixhumi se-alpha esibhekene nesizinda esimhlophe. Uma ufuna ukubukeka okucacile esinqumweni, bheka ukubonakala okucacile okuqaphelayo TIFF endaweni ye TIFF=JPG. 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 ku-GIF futhi axhunywe kabusha ku-TIFF 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-TIFF?

Ikhamera EXIF (ISO, i-shutter, i-lens, i-GPS coords) igcinwa ngokuzenzakalela ngesikhathi GIF → TIFF 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-TIFF 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 TIFF 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 TIFF?

Iphutha ngu 1:1 — TIFF 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 TIFF ingaba ncane ngaphandle kwezinto ezibonakalayo ezibonakalayo?

Nge-JPG / WebP, umgangatho 75-85 uvame ukuthola i-TIFF 60-80% encane kuna-GIF ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. Nge-lossless TIFF (PNG, TIFF), cabanga ukulondoloza okuncane — ngokuvamile 5-30% nge-deflate / LZW yokucindezela okungcono. 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 isikhathi eside, 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 (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.

TIFF

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