Mafayilo a TIFF amathandizira kuzama kwa ma bit ambiri komanso kupsinjika kosataya, komwe ndi koyenera kujambula zithunzi ndi kusindikiza mwaukadaulo.
Ntchito Zofala
Kujambula zithunzi ndi kusanthula kwaukadaulo
Mafayilo azithunzi okonzedwa kusindikizidwa
Kusunga zithunzi zapamwamba kwambiri
TIFF Mafunso Ofunsidwa Kawirikawiri Okhudza Kusintha kwa Anthu
Kodi ndi chiyani TIFF fayilo?

TIFF ndi lossless raster chithunzi mtundu kuti amasunga aliyense pixel popanda compressing artifacts. TIFF ndi bwino ku screenshots, line art, zolemba ndi zosalimba mapiko ndi aliyense chithunzi kuti adzasinthidwa m'tsogolo.
Sizimasunga deta ya pixel. TIFF imasunga chithunzicho mwatsatanetsatane kuposa momwe imapangira, kotero kusintha pakati pa mitundu iwiri yopanda kuwonongeka kumatha kusinthidwa ndikutha kuchitidwanso mosatha popanda kuwononga. Zomwe zingathe kuwonongedwa ndi zonse zomwe zili m'ma pixels - ma profiles amtundu, kuwala, animation, metadata yophatikizidwa - chifukwa chithandizo cha iwo chimasiyana kwambiri pakati pa mitundu kuposa momwe kusungira ma pixels kumachitira. TIFF ndi chonyamula zambiri kuposa codec: likhoza kunyamula uncompressed, LZW, ZIP kapena ngakhale JPEG deta, pa mpaka 32 mabit pa channel, ndi masamba ambiri mu fayilo imodzi.
N'chifukwa chiyani ma scanners ndi ma archives amapanga TIFF?
+
Chifukwa chake imasunga chithunzi chothamanga popanda kuzindikira chilichonse kwa inu - palibe kutsitsa kwa lossy komwe kumapangidwa pakupanga, komanso malo a metadata omwe akufuna ntchito ya deta. Izi zimapangitsa kuti ikhale mtundu woyenera panthawi yojambula ndi yovuta yogawa, chifukwa chake ma archives amasunga mtundu woyamba ndikupatsanso zidutswa zosinthidwa. TIFF imagwira ntchito ndi CMYK, 16-bit deepness, embedded ICC profiles ndi multi-page documents, zomwe ndi zomwe zimafunikira kusindikiza ndi kusungira ntchito.
Kodi TIFF imasunga kumbuyo kowoneka bwino?
+
Yes — format amasunga weniweni alpha channel, kotero cut-out logos, zinthu shots ndi overlays kusamalira khalidwe lawo lowala mosafika pa woyera rectangle. Kusintha kwa mtundu popanda alpha ndi pamene izo zimakhala zoipa: zowonekera zooneka bwino nyanja ndi kulowa ndi woyera, nthawi zambiri woyera kapena wakuda, ndi palibe njira yopita kumbuyo pang'ono kuteteza mfundonso.
Kodi TIFF imatha kusamalira CMYK yosindikiza?
+
Ikhoza, amene ndi chifukwa chake fayilo kuchokera kusindikiza workflows nthawi zina kuwoneka zosadziwika pazenera: zobiriwira ndi zowunikira za ink peresenti kwa kusindikiza kuposa kuwala kwa monitor. ambiri web-facing mtundu ndi RGB okha, kotero kusintha ayenera kutanthauzira, ndi kutanthauzira ndi zosakira - saturated cyan ndi orange shift kwambiri. Kwa chilichonse kuyendera kwa wosindikiza, kusamalira oyambirira mbali iliyonse inu kusintha.
Kodi ndi chinthu chofunika kuti TIFF ali ndi zaka zoposa makumi atatu?
+
Age yekha si vuto - angapo mtundu kuchokera kuti nthawi ndibe bwino, makamaka chifukwa chilichonse chili ndi zaka kuti akwaniritse iwo. Zimene zikukhudza ndi zimene nthawi anaganiza: mavidiyo ang'onoang'ono, mofulumira processors, palibe netiweki, ndi zizindikiro aliyense anafunikabe. Pamene zimene anaganizabebe, mtundu ndi bwino. Pamene iwo sachita, kuti ndi chifukwa chosintha. TIFF ndi Tagged Image File Format kuchokera 1986, ndipo ndi mtundu wa skanning, kufalitsa ndi archiving makampani standardized pa.
Kodi kamera ndi malo a metadata amasungidwa pamene ndimasintha TIFF?
+
Zimachitika pamene mtundu woyenera umathandizira - kamera ya kamera, kuwala, nthawi yotenga, ndi GPS coordinates ngati chipangizocho chidalemba. Kuti chachiwiri chimayenera kuganiziridwa pambuyo pa kufalitsa: chithunzi chochokera pafoni chimatha kubweretsa malo oyenera omwe adatengedwa. Kuchotsa metadata nthawi yosintha pamene chithunzi chikuyenda komweko kwa anthu.
Kodi ndimafunikira mapulogalamu a Adobe kuti nditsegule TIFF?
+
Kuti muwerenge, palibe - mtunduwu ndi wolemba ndi wodziwika bwino, ndipo pali zida zambiri zotsegulira. Kuti mudziwe zonse zomwe zimapezeka, pulogalamu yoyamba ndi yolemba, ndipo mafayilo omwe amatengera mfundo zake zitha kusiyana. Kusintha kwapafupi sikungofuna chilolezo cha Adobe, komanso sichiyenera kukhazikitsidwa pamalo.
