Image deta ndi JPEG woyera; JFIF amatiuza kutalika ndi thumbnail nyanja m'madera a m'madera, kotero.jfif ndi.jpg ndi zithunzi chimodzimodzi. Bitstream ndi yofanana ndi.jpg: DCT-ochokera lossy kusamvana, nthawi zambiri ndi 4:2:0 chroma subsampling, wopangidwa mu JFIF kapena Exif header.

Choyambirira ndi 1:1 — JPEG yanu imasunga kukula kwa pixels ya chiyambi JFIF. Ngati mukufuna kusintha kukula kwa chithunzi ngati gawo la kusintha, kugwiritsa ntchito /resize-image/ pambuyo posintha, kapena kugwirizana ndi /image-resize/ ntchito.

Kodi JPEG ingakhale yotani yotsika mtengo popanda zosaoneka?

Kwa JPEG yopanda malire (PNG, TIFF), mutha kuyembekezera kupulumutsa pang'ono - nthawi zambiri 5-30% pogwiritsa ntchito kutsitsa bwino / LZW. JPEG ndi kuwonjezeka ambiri kamera, scanners ndi Unix-origin mapulogalamu amakonda, ndipo ndi wodziwika padziko lonse.

Kodi JFIF fayilo yanga ndi yapadera nthawi yosintha?

Ndikoyenera - mafayilo a JFIF omwe amatulutsidwa amachitidwa m'mawu osiyana ndi omwe amagwira ntchito ndipo amasungidwa m'maola ochepa. Sitingawerenge, sitisunga nthawi yayitali kapena sitigawana deta ya pixel.

Kodi wosintha JFIF kupita ku JPEG amagwira ntchito kwa zithunzi zochuluka kwambiri (50MP +)?

Yesani kwaulere mpaka 100 MB. Premium imatha kusamalira ma inputs akuluakulu (300 MB+) ndi kuwala kwa pixels (16-bit PNG, 32-bit float TIFF). Pipeline imayenda m'maudindo kuti kukumbukira kukumbukira kusinthidwa ndi kuchuluka kwa maudindo, osati kuchuluka kwa ma pixels.

N'chifukwa chiyani JPEG yanga yosinthidwa ndi yayikulu kapena yaying'ono kuposa momwe ndimayembekezera?
