TIFF kuya GIF Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele lakho TIFF futhi umguquli ufaka ukulungisa umgangatho okwaziyo ifomu le GIF. Ukungabi nalutho GIF (PNG, TIFF, BMP) wonke ama-pixel agcinwa; ukungabi nalutho GIF (JPG, WebP) ungalungisa umphumela womgangatho ngaphambi kokulayisha. 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 ayilahleki kodwa iphoqeleke kumbala we-256-palette ngefremu ngayinye, usebenzisa ukucindezeleka kwe-LZW nokucacile kwe-binary ngombala owodwa.

Yini ezoba nezinga le-layers kuhele lwami TIFF?

Zihlanganiswa, ngokuqhubekayo, kusithombe esifanayo esihlobene. Amamodali wokuxuba, ama-masks, ama-layers wokuhlela kanye nombhalo ohlelayo wonke axazululwa kumapixels aphesheya ngoba GIF ayikho isakhiwo esigcinayo. Gcina i TIFF njenge-master esebenza kahle futhi uthathe i GIF ngokuqinile njenge-export. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC efakwe ngaphakathi namaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingayo ukuphrinta nokugcinwa kwemisebenzi. I-GIF's 256-color ceiling ibulala ama-gradients namavidiyo ahlala, futhi i-file sizes yayo ye-animations i-order of magnitude ebi kunayo i-WebP noma i-MP4.

Ingabe umbala wami we-CMYK uzoqhubeka nokuguqulwa ku GIF?

Kuguqulwa ku sRGB, ngoba GIF ayikho indlela ye CMYK. Ukusetshenziswa kweskrini lokho kulungile. Uphrinta okuhweba akuyona - i-gamut shift ishintsha indlela imibala egcwele ikhiqizwa ngayo kuphrinta, ngakho-ke thumela umphrinta okuqala TIFF endaweni ye-GIF.

Ingabe i-GIF igcina i-EXIF data kusuka ku-TIFF yami?

Ngokungajwayelekile yebo, lapho injongo ikhona khona ukuze ibekwe khona - imodeli yekhamera, izilungiselelo zokuveza, ilensi kanye ne-GPS coordinates zonke zihamba phambili. I-GPS iyindawo efanele ukucabanga ngayo: uma isithombe sizoshicilelwa, sebenzisa i-strip-metadata option ukuze ungasakazi lapho isithombe sithathwe khona. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwefayela ezimbonini ezijwayelekile.

Ingabe kukhona okulahlekile ekushintsheni phakathi kwe TIFF ne GIF?

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 TIFF kuya ku GIF ukuguqulwa kugcina ukubukeka okucacile?

Ukubukeka okucacile kuqhubeka uma GIF 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 GIF endaweni ye-GIF=JPG. I-GIF iyifomethi ye-CompuServe ye-1987, futhi isizathu esingenalutho sokuthi ikhulele ukuthi isebenza ngokuzijabulisa.

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

Amaprofayili wemibala we-ICC afakwe ngaphakathi afundeka kusuka ku-TIFF futhi axhunywe kabusha ku-GIF 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 TIFF kuya ku GIF?

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

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

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

Ingabe i GIF ingancane uma ingabonakali i-artifacts?

I-JPG / WebP, umgangatho 75-85 uvame ukuthola i-GIF 60-80% encane kune-TIFF ngaphandle koshintsho olubonakalayo emgwaqweni wokubuka ojwayelekile. I-lossless GIF (PNG, TIFF), cabanga ukulondoloza okuncane - ngokuvamile 5-30% nge-deflate / LZW yokucindezela. Umbukiso we-GIF udlala kuwo wonke amasayithi — amaklayenti we-imeyili, ama-forum, ama-apps wokuxoxa nama-browser wonke awenza ngaphandle kokuxoxa nge-codec.

TIFF

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