1Ulengeza JPEG images yomwe mukufuna kulemba, kale pa kukula kwake komaliza - kujambula kwamadzi kumachitika pambuyo posintha, osati pambuyo pake.
2Kutsitsa logo yowoneka bwino ya PNG kapena kulemba mawu anu, kenako kusankha font, mtundu ndi kuwala.
3Sankhani malo, kapena kusintha kuti tiles kubwereza pamene m'mphepete mwa mzere wokha chiwonetsero chazithunzi ndi bwino kwambiri kuchotsa.
4Pangani fayilo ya watermarked JPEG; palibe china chomwe chimawonjezerapo.
Wolemba wamadzi JPEG Mafunso Ofala
Kodi mtundu wa fayilo umakhudza mmene watermark imawonekera?
+
Ndikofunika. JPEG ndi codec yofanana ndi JPG pansi pa chida chowonjezera - DCT yofanana, tambala yofanana yowerengera, palibe chomwe chimasintha ndi dzina la fayilo. Izi zimayendetsa momwe chiwonetsero cha semi-transparent chimayenera kuphatikizidwa ndi zomwe zili pansi pazolemba.
Pali china chilichonse chokhudzana ndi JPEG chomwe chimafunikira kudziwa?
+
Yes — the.jpeg ndi.jpg zowonjezera ndi chimodzimodzi bitstream, choncho palibe apa amachita mosiyana ndi.jpg — zosintha zokha za dzina la fayilo. Zimakhudza pamene mu workflow yanu mfundo iyenera kuchitidwa.
Kodi watermark imateteza ntchito yanga?
+
Kuchotsa mfundo za m'mbali kumaletsa kugwiritsa ntchitonso kwa nthawi yaitali ndipo kumakupatsa mwayi; sikuti ndi chitetezo. Mzere wa m'mbali ungagwiritsidwe ntchito ndipo mzere wowala ungagwiritsidwe ntchito. Ngati kuteteza ndi chinthu chofunika, mzere waukulu wowala kwambiri m'mbali ndi wovuta kwambiri kuchotsa kuposa mzere wowala kwambiri m'mbali.
Kodi ndiyenera kulemba madzi a watermark pazithunzi zakale kapena zatsopano?
+
Watermark the final deliverable at its final size, so the mark stays readable and proportional. Watermarking a master you will process again means the mark gets resampled and compressed along with everything else.
Kodi chimachitika ndi EXIF ndi mtundu wa profile deta?
+
EXIF ya kamera (ISO, shutter, lens, GPS) ndi ICC profile yophatikizidwa imapita ku default, chifukwa kuchotsa profile ndi komwe kumachititsa kuti mabala azisintha pa kulowanso.
Kodi Wolemba wamadzi JPEG imawononga chilichonse?
+
No. Wolemba wamadzi JPEG ndi ufulu popanda akaunti, palibe watermark pazotulutsa ndi palibe khoma lolembetsa m'mbuyo mwa kutsitsa. Kutsitsa kumatha kuchotsanso nthawi yochepa pambuyo pomaliza ntchito.
Kodi pali malire a kukula kwa fayilo pa Wolemba wamadzi JPEG?
+
Yai: maakaunti aulere amapanga zithunzi mpaka ku 5 MB, zomwe zimakhudza kwambiri kamera iliyonse JPG ndi foni; ntchitoyi imachitika ndi libjpeg-turbo ndi libwebp, mabuku omwewo omwe wolemba deta amagwirizana nawo. Mafayilo akuluakulu ndi chinthu chimodzi chomwe chimalepheretsa chida chosalipira, ndipo chida chokha chili ndi fayilo imodzi kuposa fayilo imodzi.
Nchifukwa chiyani malo a PNG amalandira Wolemba wamadzi JPEG?
+
PNG.to imapangidwa m'njira yomwe mumagwiritsa ntchito pamene simungathe kuwononga pixel: osatha, alpha-oyenera, ndi yankho loyenera kwa zithunzi zazithunzi, ma logo, line art ndi chilichonse chomwe chili ndi maziko olimba. Ntchito ya chithunzi siyimangokhala ndi gawo limodzi: anthu amafika kuti asinthire mtundu ndi kuchoka kufunikira chithunzi cha mtundu wina, kulemera kosiyana kapena mtundu wina. Kuyendetsa Wolemba wamadzi JPEG pamodzi ndi kutsitsa, ma caps amtundu umodzi ndi akaunti imodzi ndichifukwa chake ndi apa ndipo si pa tabu yachiwiri.
Kodi ndingachite chiyani ndi zotsatirazi pamene Wolemba wamadzi JPEG yatha?
+
Wosintha patsamba lino amasintha zithunzi ku PNG, JPG, WebP, GIF ndi SVG - zomwe ndi njira yomwe lamulo la kuwala kwa chilengedwe limapangidwa. Izi ndi njira yomwe anthu ambiri adapita, ndipo amachita izi pambuyo pa Wolemba wamadzi JPEG kuposa kale, kumatanthauza kuti kusintha kwa ntchito kumachokera ku fayilo yomwe mwamaliza kukhazikitsa.
Kodi Wolemba wamadzi JPEG pano ndi chinthu chomwecho chomwe masamba a sibling amayendetsa?
+
Magalimoto amagawana - mabuku omwewo, ogwira ntchito omwewo, ma limits omwewo. Zosiyana ndi malangizo, ndipo malangizowa amayamba kuchokera ku chinthu chimodzi chokhudza mtundu womwe umagwiritsidwa ntchito patsamba lino: palibe slider yabwino yosayenera - PNG imayenda m'mphepete mwa maulendo a bit-exactly, choncho chinthu chokhacho chomwe chimasintha mtengo wanu ndi kukula kwa fayilo. A PNG sitepe amaganiza za komwe PNG ndi malo abwino komanso komwe si, ndipo lamuloli limatanthauza zambiri kuposa batani.
Kodi ndiyenera kukhala ndi akaunti, ndipo kodi zinthu zina zimasunga?
+
Sichingakhale akaunti, ndipo palibe chomwe chimasunga: zotsitsa zimachotsa ntchito za ogwira ntchito pambuyo pomaliza ntchito, ndipo palibe chomwe mumapanga chimasinthidwa, kupezeka kapena kugwiritsidwa ntchito kwa chilichonse. Maakaunti aulere alipo kwa mbiri ndi kukula kwa batani, osati kulowa.
