Sinthani TIFF ku SVG

Kusaka kumasintha malo a pixel kukhala maulendo, omwe amagwira ntchito bwino kwa malogo, mapangidwe a m'mizere ndi zithunzi zamtundu wa flat-colour ndi mipaka yosaoneka bwino. Fotogalamu siyimakhala ndi mipaka imeneyi, chifukwa chake kusaka kumabweretsa kapena kulinganiza kovuta kapena SVG ndi maulendo ambirimbiri omwe ndi akulu kwambiri komanso othamanga kwambiri kujambula kuposa oyamba. SVG sangakhale chithunzithunzi cha zithunzi - kujambula zithunzi kumabweretsa kuyerekezera kopanda nzeru kapena fayilo yochulukirapo kuposa raster yoyamba.

Amapepuka, nthawi zonse, kukhala chithunzi chimodzi chophatikizidwa. Momwe zimaphatikizidwa, masks, ma layers osinthika ndi mawu osasinthika onse amatulutsidwa ku pixels omaliza chifukwa SVG sichimakhala ndi chilengedwe chokhala nawo. Tengani TIFF ngati wogwira ntchito wamkulu ndipo gwiritsani ntchito SVG mwakhama ngati kutumiza kunja. TIFF imagwira ntchito ndi CMYK, 16-bit deepness, embedded ICC profiles ndi multi-page documents, zomwe ndi zomwe zimafunikira zosindikiza ndi zosunga zobwezeretsera.

Imakhala yosinthidwa kukhala sRGB, chifukwa SVG siyimakhala ndi njira ya CMYK. Pogwiritsa ntchito chophimba, izi ndi zomwe mukufuna. Pogwiritsa ntchito chophimba cha malonda, sichingakhale choncho — kusintha kwa gamut kumasintha momwe mabala osatumizirana amawonekera pa chophimba, choncho itumiza chophimba cha TIFF choyambirira kuposa SVG.

Popanda malire, yeah, komweko TIFF ndi Tagged Image File Format kuchokera 1986, ndipo ndi mtundu wa skanning, kufalitsa ndi archiving makampani standardized pa.

Mu SVG, malemba ndi malemba anzeru — kusankhidwa, kufufuzidwa ndi re-styleable, ndipo amafuna font kuti azikhalapo kapena embedded kuti aonedwe monga analonjeza. Kusintha kuchokera SVG amasintha kuti malemba mu pixels kapena mu malemba a dokumento kutengera cholinga; kusintha ku SVG amapereka okha malemba anzeru ngati chiyambi anali ndi malemba latsopano.

Palibe pixel deta, palibe. Both formats kusungira chithunzi popanda lossy kusamvana, kotero chithunzi chimene chimatuluka ndi yofanana ndi imodzi yomwe inapita mu ndi kusintha angagwiritsidwe ntchito mobwerezabwereza. zimene kusintha ndi kukula kwa fayilo, ndi zimene ntchito kuyenda - kuwala m'lifupi, embedded profiles, ma layers ndi animation onse anathandiza mosiyana pakati lossless mtundu. 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. SVG amasunga mawonekedwe monga maulendo a matekinoloje ndi malemba monga malemba, osati monga ma pixels, kotero ndi buku lazolemba kuposa raster grid.

Kuwala kumatha kupezeka pamene mukuyenda ku PNG, WebP, TIFF, GIF, kapena SVG. Kusintha kwa JPG kumadula chingwe cha alpha pambuyo pa khungu loyera - ngati mukufuna kuwala, gwiritsani ntchito mtundu wowala womwe umadziwa kuwala kuposa SVG.

Ma profiles a ICC a ICC amawerengedwa kuchokera ku chiyambi TIFF ndipo amaphatikizidwanso ku SVG komwe mtundu umathandizira (JPG, PNG, TIFF, WebP). Ma formats osagwirizana ndi ma profiles amabwerera ku sRGB.

EXIF ya kamera (ISO, shutter, lens, GPS) imasungidwa mwanjira yosasinthika panthawi ya TIFF → SVG yosinthira pamene mitundu iwiri imathandizira metadata. Pezani njira yopezera ufulu kuti muchepetse metadata pambuyo potsitsa ngati mukufuna kugawana zithunzi popanda geolocation.

Yai - titha kutsitsa mafayilo ambiri a TIFF ku gawo lotsitsa ndipo timawaika m'gulu limodzi. Ogwiritsa ntchito aulere amalandira 100MB pa fayilo; Premium siyimakhala ndi fayilo ya fayilo ndipo imagwira ntchito zambiri, chifukwa chake 200-image batch imakhala yomaliza m'maola awiri.

Kuti tisinthe mtundu wokha, tigwiritsa ntchito libwebp / ImageMagick yomweyo yomwe wolemba desiki agwiritsa ntchito, ndi mtundu wofanana. Kusiyana ndi kuti zida za desiki zimatsegula fayilo imodzi nthawi imodzi; timavomereza masamba ndi kuwayendetsa mofanana.
