TIFF Amathuluzi

Guqula TIFF kuya futhi kusuka kumafomethi ahlukahlukene

TIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele le-TIFF?

I-TIFF iyifomethi yesithombe se-raster engalahlekelwanga egcina wonke ama-pixel ngaphandle kokucindezeleka. I-TIFF ilungele kakhulu ukuthwebula izithombe, umdwebo we-line, ukudweba ngemiphetho eqinile kanye nanoma iyiphi isithombe esizoguqulwa.

Ingabe kukhona okulahlekile uma i-TIFF iguqulwa ibe yifomethi engekho emthethweni?

Akukho data ye-pixel. TIFF igcina isithombe ngokugcwele ngaphandle kokuyifinyelela, ngakho ukuguqulwa phakathi kwefomethi ezimbili ezingalahleki kuphindeka futhi kungaphinda kuphindeka ngaphandle kokulahlekelwa. Okungakwazi ukulahleka yizinto zonke ezingaphansi kwe-pixels — amaprofayili wemibala, ukubukeka okucacile, ukubukeka, i-metadata efakwe — ngoba usizo lwalezi luhluka kakhulu phakathi kwefomethi kune-pixel storage. 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.

Kungani iziskaneri nezigobo zefayela zikhiqiza TIFF?

Ngenxa yokuthi igcina isithombe esithathwe ngaphandle kokucabanga nganoma yini kuwe - akukho ukucindezeleka okulahlekile okuthosiwe ekuthatheni, futhi indawo yedatha yemeta edinga ukuphuma kwedokhumende. Lokhu kwenza kube yifomethi efanele engxenyeni yokuthwebula futhi inzima ukusakaza, ngakho amafayela agcina okubhaliwe futhi adlulise amakhophi aguqulwe. I-TIFF iphatha i-CMYK, 16-bit ububanzi, i-ICC ifaka amaprofayili namadokhumende amakhasi amaningi, okuwukuthi okuthile okudingekayo ukuphrinta nokugcinwa kwemisebenzi.

Ingabe i-TIFF igcina isizinda esicacile?

Yebo - ifomu ligcina i-alpha channel engokoqobo, ngakho-ke ukucisha izithonjana, izithako ezibomvu kanye nezibopho zigcina ukubukeka kwazo ngaphandle kokufika ku-rectangle ebomvu. Ukushintsha kufomethi ngaphandle kwe-alpha kuyilapho kudlula khona okungalungile: izindawo ezibonakalayo zigcwele umbala oqinile, ngokuvamile omnyama noma omnyama, futhi akukho indlela yokubuyela emuva encane yokufihla isithako futhi.

Ingabe TIFF igcina umbala we-CMYK wokuphrinta?

Kungenza, ngakho amafayela ephrinta asuka emithonjeni yomsebenzi avame ukubukeka ahlukile kusikrini: amamibala acaciswa ngezinga le-ink elisetshenziswe ephrinteni kunesikhashana se-monitor. Amafomethi amaningi wewebhu abhekene nawo yi-RGB kuphela, ngakho ukuguqulwa kufanele kuguqulwe, futhi ukuguqulwa kulinganiselwa — u-cyan ogcwele no-orange ushintsho kakhulu. Kunoma yini ehamba kuphrinta, gcina okuyinhloko kubhekene nanoma yini oguqula.

Ingabe kubaluleke ukuthi TIFF ingaphezu kweminyaka engu-30?

Ubudala bukhona akuyona inkinga - amafomethi amaningi onyaka akhona alungile, ngokucacile ngoba konke kudlule iminyaka eminingi ukuwafaka. Okubalulekile ukuthi unyaka uthathe isinqumo: amafayela amancane, amaprosesa aphansi, akukho nethiwekhi, futhi amakhono angeke afune umuntu. lapho amanani ahlala khona, ifomu lilungile. lapho ayikho, lena yisizathu sokushintsha. I-TIFF iyifomethi yefayela lesithombe ephawulwe kusukela ngo-1986, futhi iyifomethi yokuskena, ukushicilela kanye nokugcinwa kwezinto eziphilayo ezijwayelekile.

Ingabe ikhamera nendawo yedatha yemeta igcinwa uma ngiguqula i TIFF?

Ithwala lapho ifomethi efuna ukufinyelela isekela khona - imodeli yekhamera, ukuboniswa, isikhathi sokuqoqa, kanye ne-GPS coordinates uma isisetshenziswa sizorekhoda. Le yamuva ifanele ukucabanga ngaphambi kokuthunyelwe: isithombe esihamba phambili esisuka kufoni singathwala indawo efanele ethathwe. Nciphisa i-metadata ngesikhathi sokushintshana uma isithombe sihamba endaweni esemthethweni.

Ingabe ngidinga isofthiwe ye-Adobe ukuvula i-TIFF?

Ukufunda, cha — ifomu libhalwe futhi lisetshenziswa ngokubanzi, futhi kunezithuluzi eziningi ezivula. Ukusebenza okuphelele, isicelo esiqalayo sihlala siyisibonelo sokusetshenziswa, futhi amafayela abhekene nezici zayo ezikhethekile angahluka kwezinye izindawo. Ukuguquka lapha akudingi ilayisense ye-Adobe futhi akukho kufaka okungaphakathi.

Ngabe kufanele ngiguqule i-TIFF ibe yifomethi ehlukile?

Guqula i-TIFF ibe yi-JPG noma i-WebP uma isizinda esizosetshenziswa siwu-webu ovulekile noma i-imeyili, lapho ubukhulu befayela elincane libalulekile kune-pixel-per-faithfulness. Ukulungelelaniswa kwe-TIFF kuyinkinga yayo - ama-TIFF amabili angakhiwa ngendlela ehlukile yokuthi isofthiwe efunda enye iphutha kwezinye - futhi amafayela akhulu.

Ingabe ukushintsha i-TIFF kuzonciphisa ukhwalithi yesithombe?

Uma uguqula i-TIFF ibe yifomethi engekho emthethweni, ama-pixels agcinwa ngokugcwele. Uma uguqula i-TIFF ibe yifomethi engekho emthethweni njenge-JPG, umbhalo-mbhalo ungenza ubukhulu-no-umgangatho-ubukhulu-ubukhulu-ukulawula ngokusetshenzisiwe kwekhwalithi ye-output.
