Ukungabikho kolahleko JPG (PNG, TIFF, BMP) yonke ipixel igcinwa; ukungabikho kolahleko JPG (JPG, WebP) ungalungisa umgangatho womsebenzi phambi kokukhuphela. I-TIFF yindawo yokugcina engaphezulu kwe-codec: inokuphatha i-data engacinezelwanga, i-LZW, i-ZIP okanye nakwi-JPEG, ukuya kuthi ga kwi-32 bits kwisiqhagamshelanisi ngasinye, ngeephepha ezininzi kwifayili enye. I-JPG ilahlekile: umfanekiso uguqulwa nge-DCT, u-quantized, kunye ne-entropiy-coded, ngeqhosha lomgangatho elilawula ukuba kuphi okuninzi okulahlekileyo.

Ithini into eyenza amanqanaba efayili yam TIFF?

Ziqhotyoshelweyo, ngokusisigxina, kumfanekiso omnye odityanisiweyo.

Kwi-lossless JPG (PNG, TIFF), lindele ukonga okuncinci - ngokuqhelekileyo 5-30% nge-deflate / LZW uxinzelelo olungcono. I-JPG icinezela imifanekiso ebonakalayo ngokumangalisayo kwaye ifundeka ngazo zonke izixhobo, umkhangeli zincwadi nomshicileli okhoyo.
