2Sankhani kukula kwatsopano: kwa chithunzi, kutalika ndi kukula kwa pixels ndi kukana kwa mtundu wa mawonekedwe; kwa kanema, imodzi mwamapangidwe osankhidwa kuchokera ku 1920x1080 kupita ku 640x360.

Kusintha kwa TIFF Mafunso Ofala
Kodi Kusintha kwa TIFF imasintha bwanji ma dimensions?
+
M'malo mwake, pixels ndi resampled ndi Lanczos wochotsa ndi kulemba m'mbuyo losslessly, choncho chokha inu kuwononga ndi deta kuti mwamsanga sangakhale m'malo m'ma pixels pang'ono; palibe kuwonjezera ndi encoder pa pamwamba. Kwa chithunzi inu mumapereka kutalika ndi kulemera mu pixels; kwa kanema inu kusankha imodzi mwa kukula preset. It works from the original rather than from a previously resized copy.
Kodi ndingatani kuti ndizisunga kusiyana kwa mavidiyo, kapena kuletsa kukula kwa zithunzi?
+
Kuphatikiza apo, kuwonjezera pa kuwonjezera maonekedwe a mfundo, inu mukhoza kuwonjezera maonekedwe a mfundo. Both. Lock ratio ndi mfundo imodzi imachokera ku ena, amene ndi zimene mukufuna pafupifupi nthawi zonse. Unlock izo ndi inu mupeza moyenera mfundo inu analemba, pa mtengo wa stretching — zothandiza kwa chigawo chokhazikika, zoipa kwa chithunzi.
Kodi mtundu woyamba umakhudza zotsatira za kusintha kwa kukula?
+
Izi sizotheka. TIFF ndi archiving wonyamula: lossless LZW kapena DEFLATE, 16-bit-pa-channel m'mphepete, CMYK, ndi masamba ambiri mu fayilo imodzi. Izi ndi zimene amaganiza ngati kuchepetsa wapamwamba ndi kokha nkhani ya pixels kapenanso nkhani ya re-encoding.
Kodi pali chinachake chokhacho cha TIFF chomwe ndingawone?
Kodi ndi chiyani cholakwika chofala kwambiri pamene mukusintha kukula kwa TIFF images?
+
Upscaling. Kukula sikungayambitse mfundo zosadziwika zomwe sizikuwonetsedwa, choncho zotsatira zake ndi mtundu wolimba wa mtundu woyamba ndi kukula kwakukulu. Kawirikawiri, sinthani kukula kwa chithunzicho kuchokera pazomwe muli nazo, ndipo sinthani kukula kwake kamodzi kokha, osati m'madera.
Kodi ndiyenera kulenga maudindo ati?
+
Match the slot it will live in. A full-width web hero rarely needs more than 1920 pixels wide, a content image 1200, a thumbnail 400, and doubling those numbers covers high-DPI screens. Anything beyond that is bytes nobody sees.
Kodi ndingapeze chiyani pa Kusintha kwa TIFF?
+
PNG, BMP ndi TIFF ndi mafomu a raster osatha omwe amagwira ntchito moyenera, ndipo mabungwe othamanga (JPG, WebP, GIF) amagwira ntchitonso ngati mukufuna kuwagwiritsa ntchito pamodzi. TIFFs osiyanasiyana amapezeka ndikuyang'aniridwa patsamba ndi tsamba.
Kodi pali malire a kukula kwa fayilo pa Kusintha kwa TIFF?
+
Yesani: maakaunti aulere amapanga zithunzi mpaka 5 MB; mabungwe osatha kuwononga amawononga malirewo mofulumira kuposa zithunzi, chifukwa palibe chomwe chimatulutsidwabe. Ngati muli pamwamba pa izi, kusinthidwa kwa PNG kumayamba nthawi zambiri kumatha kukwanira - BMP ndi nthawi yambiri ya zaka makumi asanu ndi awiri ndi kukula kwa chithunzi chofanana ndi PNG.
Kodi Kusintha kwa TIFF idzachepetsa mtundu wa TIFF images wanga?
+
Sichoncho. A lossless kuchokera round-trips bit-exactly, kotero ngati inu mosabisa akufuna kwa lossy kutulutsa mtundu pixels amene anabwerera ndi pixels amene anapita mu. Izi ndi chifukwa chakuti zonse kutsatira ntchito mu izi banja pamene inu mwakhala kusinthira.
Kodi ndingagwiritse ntchito Kusintha kwa TIFF pa TIFF images angapo nthawi imodzi?
+
Yes — kutsitsa set ndi iwo kusonkhana mofanana pansi pa imodzi set of settings. Lossless owona ndi zikuluzikulu, kotero lalikulu gulu ndi kugwirizana ndi kutsitsa wanu galimoto kuposa ndi kusonkhana yekha.
Kodi alpha channel kupulumuka?
+
Ndiko. PNG ndi TIFF zimagwiritsa ntchito ma channels a 8-bit alpha ndipo zimasungana mpaka pamapeto. Zimakonzedwa ngati mwasankha mtundu womwe sumakhala ndi ma channels alpha, ndipo m'njira imeneyi ma pixels owoneka bwino amaphatikizidwa pa mthunzi wobiriwira.
Kodi Kusintha kwa TIFF imawononga chilichonse?
+
No. Kusintha kwa TIFF ndi ufulu popanda akaunti ndi awonjezera palibe watermark. Upload ndi zotsatira zimathetsedwa mwamsanga za 24 maola pambuyo ntchito, zomwe zimasiya nthawi yotsitsa zotsatira.
