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, mafano ndi zosalimba mapiko ndi aliyense chithunzi kuti adzasinthidwa m'tsogolo.
TIFF imasunga chithunzicho moyenera kuposa kuika kwa pixel, kotero kusintha pakati pa mitundu iwiri yopanda kusowa ndi yosinthika ndipo imatha kuchitidwa mobwerezabwereza popanda kuwononga. Zomwe zingathe kuwonongeka ndi zonse zomwe zili m'ma pixels - ma profiles amtundu, kuwala, animation, metadata yophatikizidwa - chifukwa chithandizo cha iwo chimasiyana kwambiri pakati pa ma formats kuposa momwe kusungira ma pixels kumakhalira. TIFF ndi chonyamula zambiri kuposa codec: likhoza kunyamula uncompressed, LZW, ZIP kapena ngakhale JPEG deta, pa mpaka 32 bits pa channel, ndi masamba ambiri mu fayilo imodzi.
N'chifukwa chiyani ma scanners ndi 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 zosindikiza ndi zosunga zobwezeretsera.
Kodi TIFF imasunga kumbuyo kowonekera?
+
Yes — format amasunga weniweni alpha channel, kotero cut-out logos, zinthu shots ndi overlays kuteteza khalidwe lawo lowala mosafika pa woyera rectangle. Kusintha kwa mtundu popanda alpha ndi pamene izo zimakhala zoipa: zowonekera zowala nyanja ndi kulowa ndi wolimba mtundu, nthawi zambiri woyera kapena wakuda, ndi palibe njira yopita kumbuyo pang'ono kuteteza mfundoyonso.
Kodi TIFF imatha kusamalira CMYK yosindikiza?
+
Ikhoza, amene ndi chifukwa chake fayilo kuchokera kusindikiza workflows nthawi zina kuwoneka zosadziwika pazenera: zobiriwira ndi zoperekedwa mu inki peresenti kwa kusindikiza kuposa kuwala kwa monitor. ambiri web-facing mtundu ndi RGB okha, kotero kusintha ayenera kutanthauzira, ndi kutanthauzira ndi zosawerengeka - saturated cyan ndi orange shift kwambiri. Kwa chilichonse kuyendera kwa wosindikiza, kusamalira oyambirira mbali iliyonse inu kusintha.
Kodi ndi vuto kuti TIFF ili 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 amasungidwira pamene ndimasintha TIFF?
